Santicorn 2019: Tide-Flooded Caverns

Santicorn baby! The second annual Santicore-alike we've organised on the OSR Discord channel!
Everyone requests a thing, we shuffle the requests around, and everyone fulfils one of them as a Christmas Santicorn gift! How wholesome!

I got this one from Wizzzargh:
"Dungeon room fills, be they tricks, traps, treasure, or monsters, for a dungeon regularly flooded by seawater at high tide. Bonus points for fills that require very different approaches at different water levels"

So here goes!


The Tide-Flooded Caverns

The smell of salt and smoke. Rumours of smugglers and sea-witches. Warnings of a rising tide that claims all who enter. Everyone in the village built on the bluffs above knows of the caves, and all are wise enough not to explore them.
At low tide the seawater slides around the cave mouths like a lover's tongue, sloshing over the slick sand and sucking mud and shifting stones of a treacherous beach.
The tide turns and waves of cold scummy seawater gush into the waiting mouths, pouring in through the twisting passages and wider caverns that honeycomb the headland.
Exploring the caves is dangerous, the rising tides changing the nature of the chambers inside, but there are stories of vast treasures and strange creatures within...

How to Use

There are 20 caverns detailed below, each with a description for Low, Mid and High Tide.
There are also 10 treasures to spice up a chamber, or maybe to find if they loot a room.
Finally, 6 random encounters because of course.
Do whatever you feel like with them!

You could roll randomly as PCs travel through the caves (maybe 1d20 for chamber and 1d20 for treasure, where treasure results 11-20 are "nothing extra"), or pre-build the cavern complex.

If you do the latter I suggest room 9 (Gillifier) be placed fairly deep in the caves, since it's a gimmick room that reverses whether you breathe air or water and it might be fun to recontextualise all the other chambers they've been in already.
Room 10 (Lamprey Witch) contains a powerful foe so could be used as a boss room if that's something you like doing.
Room 6 (Cork Golem) would make a good guard fairly close to the entrance, especially since the poor chap becomes a bit useless when the water level rises!

Either way the routes between the chambers are up to you. I envisage twisty slippery seaweedy passages that fill up at high tide.

Tracking the Tide

Time from Low to High tide is apparently 6 hours, which is a lot for your average delve, but whatever. Hopefully they get a bit trapped by the time Mid Tide rolls around and have to make some hard decisions.
I suggest having a row of six boxes like so:

☐ ☐ ☐ ☐ ☐ 
  Low 
|   Mid  |  High

Use an Overloaded Encounter Die and have result 3 say "Tide rises - Check off a tide box". That should mean you get about one box ticked off per hour.
Result 4 could even be something like "Freak Surge - treat as next Tide in cycle for next 10 minutes" to add some more watery unpredictability!

Drowning

You might have drowning rules already, but if you don't here's how I do it -

If you get a chance to take a deep breath before diving, you can hold your breath for 5 rounds +/- your Constitution modifier.
If you don't get to take a breath first, you have 1d6-1 rounds of air left, also +/- Con Mod
Once you run out of air you take 1d6 damage per round until you can breathe again.




The Chambers

1. Aqua-Pause Pillar

Any Tide:
A chamber with water seemingly frozen in time, forming a bowl-shape around a vibrating glass-and-stone pillar. The pillar is honeycombed with glass panels revealing the glowing bubbling blue liquid within. Smash the pillar and a ripple shudders through the water. Hit hard enough, the vibration stops all the water within a mile in place! It still feels like water, but it doesn't move or ripple or pour. The effect lasts for an hour, after which the water suddenly springs back to where it should have been.


2. Barnacle Spear

Any Tide:On a raised barnacle-encrusted dais in the middle of this frieze-carved chamber is a long tool with a rusty barnacle-scraping edge filed to a point on the end. Water rushes down the holes at the foot of the dais, keeping the water in this chamber knee-high.
The Barnacle Spear counts as an ordinary spear when nowhere near the sea. When it's near the sea it's a spear with powers based on the tide.
Low Tide: Ebb - on hit, get a free move and disengage backwards.
Mid Tide: Splash Zone - on hit, push everyone in front of you 20' away.
High Tide: Surge - On hit, pierce through and hit another target behind the first. This can combo indefinitely until you run out of targets. You can move up to 20' forwards between strikes.


3. Bastard Seagulls

Low Tide: Seagulls fly into this guano-covered chamber through the many small holes in the ceiling. They are fiercely territorial and massive bastards who will flock and kill in a barrage of savage pecks.

Mid Tide: Seagulls float happily on the surface of the chest-high water in this chamber, occasionally flying in and out of the many small holes in the ceiling. They are fiercely territorial and will swarm anyone who enters above the water, but won't attack anyone swimming below.

High Tide: A few seagulls bob on the surface of the neck-high water in this chamber. There's not much room though, so most of them have already flown out to the outside world through the small holes in the ceiling. Anybody with their head above the water will be attacked by the seagulls who paddle over to peck at their face - there's not enough room to swoop.

-

Bastard Seagulls
HD1 AC unarmoured ML9
Attacks: 1d2 Peck or 1d4 flyby swoop attack
Abilities: At will, a seagull can detect the distance and direction of hot potato chips within a half mile radius.
Attitude: Extremely bad-tempered. Swoop if there's room, peck if there isn't, squawk no matter what.



4. Bluebottles

Low Tide:
The slimy, lumpy floor of this chamber is covered with small pale blue pear-shaped balloons and tangles of bright royal blue tendrils. Touching a tendril brings hot red whip-like marks on the flesh and extreme agony. 

Mid Tide:
The waist-high water in this chamber has many small pale blue pear-shaped balloons bobbing about in it. Their bright blue tendrils drift about beneath the water. Wading or swimming through the water inevitably leads to these stinging tendrils drifting into you and bringing up incredibly painful whip-like welts on any body parts which went beneath the water - legs if wading, pretty much all of you if swimming.

High Tide:
Pretty blue strings drift about in the currents of this water-filled chamber, seemingly hanging from the ceiling above. If you swim through this room you are beset by the agonising stings of the tendrils and risk death by drowning.

-

Bluebottles (Hazard)
Effect:
Their tendrils bring great pain through a powerful venom. 
If touched by a tendril (even through cloth), Save vs Stun or keel over prone from the pain - you can Save again each round to recover. You take 1d4 damage each round you have clothing touching the affected body parts for the next 10 minutes. Additionally, for small areas (a hand, a foot), that body part becomes useless for the next hour. For larger areas (torso, multiple limbs), you count as having 1HP for the next hour until the pain fades away.
Main Danger:
Keeling over from the pain on land likely makes you fall onto more of them. Doing it in water risks stinging more and more of you as you stir up the water (and tendrils) in your agony, leading to your inevitable drowning.





5. Chasing Crab

Low Tide:
This crab is big and hungry and now it wants to eat YOU. It scuttles sideways at twice human speed across the wet floor of this chamber, claws bared, ready to PINCH! It will chase you until you either kill it, or get two chambers ahead of it at which point it gives up.

Mid Tide:
This crab is big and hungry and ANNOYING SLOW IN WATER! It scuttles sideways through the waist-high water at human unencumbered speed, claws bared, ready to CLAMP! It will chase you until you either kill it, or get two chambers ahead of it at which point it gives up.

High Tide:
This crab is big and hungry and AGONISINGLY SLOW SUBMERGED. It scuttles sideways under the water at a quarter human speed, claws bared, extremely FRUSTRATED! It will chase you until you either kill it, or get two chambers ahead of it at which point it gives up.

-

HD8 AC plate ML10
Attacks: 2 Pincer attacks for 1d10 each. If both hit, dents your armour giving you -1 AC until you get it repaired.
Abilities: Fast on land, slow in water. Max speed on land is twice human. Max speed submerged is quarter human.
Attitude: Chase down victims, but try to keep on land where it's fast!



6. Cork Golem

Low Tide: A huge golem made of cork stomps around this slippery chamber floored with black cave-kelp, guarding the way deeper into the complex.

Mid Tide:
A huge golem made of cork bobs around in the chest-high water in this chamber, flailing around because of how floaty it is. It's slow but powerful. Black cave-kelp waves on the floor.

High Tide:
A chamber filled completely with water, black cave-kelp waves in the water below. A huge golem made of cork is pinned to the ceiling by the water.

-

Abilities: Floats, immune to fire when wet (always in here), 1 damage per die from bashing attacks.
Attitude: Stomp around, punch people into other people, stomp on people while they're lying on the floor!


7. Dehydrated Ooze

Any Tide:
The passage slopes up to a small cave above the waterline. Inside is a crusty aquamarine bulge with gold coins glimmering under the hardened candy-like shell.
Pour a bunch of water on the lump and it rehydrates into a massive absorbent Aquamarine Goop! Run! Or kill it somehow to claim the treasure...

Attacks: 1d8 Dehydrating Slap - On hit, Save vs Doom or lose 1d4 Strength from sudden dehydration!
Abilities: If hit by a water or ice-based attack, gets an immediate free turn. If hit by a fire-based attack, stunned for a round as it loses moisture.
Attitude: Schlorp after the juiciest foe and steal all their juices!


8. Eel Pit

Low Tide: The way out of this chamber is on the other side of a 50' deep pit with a shallow pool of water at the bottom. Electric eels hide at the sandy bottom of the pit, but won't attack when the water is this shallow. How come this pit isn't just a permanent deep pool? - The water in the pit drains away slowly through narrow shafts beneath the sand.

Mid Tide: The way out of this chamber is on the other side of a deep pit with a 20' deep pool of water 30' down. Electric eels hide at the sandy bottom of the pit, and will swarm out at anyone who jumps into the water.

9. Gillifier

Low Tide:
This damp stone chamber smells of salt and earth and wet metal, small fish flop industriously around the room. The walls are lined with nooks that shimmer with layers of with valuable mother-of-pearl, and a squid peers curiously down from one of these nooks. This room reverses whether you breathe air or water for 24 hours. Anyone who spends a minute or so in this room finds it hard to breathe, and soon they discover that they have grown gills and can no longer breathe air! They begin to suffocate immediately.

Mid Tide: This stone chamber with knee-high water smells of salt and earth and wet metal. Small fish float about with their faces on the surface, gulping down air. The walls are lined with nooks that shimmer with layers of with valuable mother-of-pearl. This room reverses whether you breathe air or water for 24 hours. Anyone who spends a minute or so in this room finds it hard to breathe, and soon they discover that they have grown gills and can no longer breathe air! They must go on their hands and knees to dip their newfound gills into the low water, else begin to suffocate.

High Tide: This stone chamber with chest-high water smells of salt and earth and wet metal. Small fish float about with their faces on the surface, gulping down air. The walls are lined with nooks that shimmer with layers of with valuable mother-of-pearl. This room reverses whether you breathe air or water for 24 hours. Anyone who spends a minute or so in this room finds it hard to breathe, and soon they discover that they have grown gills and can no longer breathe air! They begin to suffocate unless they submerge themselves into the water.


10. Lamprey Witch

Low Tide: A smoky chamber with shallow pits filled with water and black oily shapes - lampreys. A smoky blue driftwood fire is in the centre of the chamber, surrounded by stones. Hiding in one of the pits during the low tide is the Lamprey Witch - an emaciated old woman with lampreys latched onto every piece of her. She always seeks more food for her children and will strike from the smoke!

Mid Tide:
A hazy chamber that smells of salt and woodsmoke. Oily black shapes writhe and twist through the knee-high water- lampreys! They wriggle through the water towards you, awful mouths wide! If you turn back you see a horrible writhing figure, a human form with lampreys latched onto every inch - the Lamprey Witch is behind you already!

High Tide: The water surges behind you, barrelling you from the tunnel into this chamber of neck-high water. When you manage to catch a breath the air smells like woodsmoke. Black oily shapes writhe towards you in the water - lampreys! They're all around you, and you hear a choking laugh as a mass of lampreys bursts from the water - a mass of lampreys in human shape - the Lamprey Witch!


Lamprey Witch
HD8 AC chain ML10
Attacks: Lamprey Toss - throw lampreys at a target, 50' range - 1d6 damage and the target gains attached lampreys equal to damage.

Abilities: Can breathe underwater, never takes damage from lampreys, breeds lampreys rapidly.
Attitude: Wants to find food for her babies! Main technique is to hang back and lob lampreys from afar, then use Lamprey Surge if she starts to get surrounded. Optimally foes will be so busy trying to get the lampreys off themselves that they can't concentrate on her!

Jumping Lamprey
HD0 (1HP) AC unarmoured ML5
Attack: Leaps up to 30' and latches on with its horrifying bloodsucking mouth! Each attached lamprey deals 1 point of damage per round. An attached lamprey can be pulled off as an Action (occupying your hand) or attacked with a weapon. If attacking, roll to hit vs AC 10. On hit, it's dead. On miss, it's dead and you deal weapon damage to the person it was latched onto.
Attitude: Swim or jump in, latch onto flesh, suck the blood!"


11. Octopus in a Hole

Mid Tide:
A fairly large cavern filled with sloshing knee-high water. The water gets blacker and murkier towards one side. A giant octopus lives here, flattening itself beneath the water. It will try to grab anybody who separates from the party and drag them to its lair, although its big body will be visible above the water as it does so!

High Tide: A fairly large cavern filled with rolling neck-deep water. The water is murky, but swimmable. A giant octopus lives here, and it will drag anyone it likes beneath the water and drag them to its lair. Anyone who seems hurt or vulnerable is a prime target!

High Tide: 
Cool water fills this flat, sandy chamber. Huge oysters lazily open and close under the water. Several of them have valuable pearls within! They snap shut if you touch them and their shells are hard as rocks, so it might take some doing to claim the pearls.


13. Reversible Merman

Low Tide: 
There is a horrifying creature in this damp chamber. Human legs from the waist down and a monstrous anglerfish head and body where the torso should be! It runs, warbling, seeking to rip gobbets of warm flesh from live prey.

Mid Tide: 
A handsome merman swims below the surface of the waist-high water in this chamber. He mimes a warning not to get too close. If you approach, he emerges from the water and shifts into a horrifying creature with human legs and an angelerfish top half which seeks to devour you!

High Tide: 
A handsome merman swims below the surface of the water that fills this chamber. He's quite pleasant if you can find a way to speak to him, but he has a horrible curse that turns him into a monster if he ever comes above water.

The crates contain valuable contraband.

Mid Tide:
A steep, high chamber with neck-high water that rises diagonally from the entrance below to another entrance above. Faint voices can be heard. There is a large wooden platform stacked with crates floating in the neck-high water, connected by a rope to an open trapdoor on the ceiling.

  6. 1d20 Jumping Lampreys

1. Smugglers
1HD AC unarmoured ML5
Attacks: Knives and long hooked poles
Attitude: Low or Mid Tide - Follow quietly until the party is in trouble, then extort or kill them. High Tide - they've been caught out in the todal surge and will work with anyone if they can escape!

Attitude: A chest-high conical shell containing an ambush predator mollusk. Waits in ambush then harpoons a victim in the ankle and engulfs them. Much more dangerous in water since its weaponised insulin cloud can prevent others fighting back. Not fast, but good at burrowing into sand and gravel.

5. Stoneshell Crab
HD2 AC plate ML5
Attacks: 1d6 pincer - On hit, grapples.

Making Magic: Redux


While my previous Wizard Downtime rules worked well enough, in the new post-apocalyptic paradigm I've been speeding up the ol' timeline so we'll get multiple years in-game per year of real time.
This is the exact opposite of a lot of games where you'll play for years and the characters only experience a few months of hooning around killing things.

Hence the very important rejigging of Downtime mechanics to taking place in units of weeks and months rather than days. Spend a month off and you'll get 4 weeks of downtime to be used at your leisure. More on that when I've rejigged the rest of the Downtime rules. For now, magic!




Chaotic Casters

I've spiced this up a bit with some new mechanics, and some juicier potion-making rules that focus on replicating found potions or generating random potions until you get one you like.

Basic Gimmick
You're rolling up to three dice, with the size of each die based on the following factors:

Care: Roll 1d6. Improve by taking more time. +1 die size per extra week taken.
Quality: Roll 1d6. Improve by paying for higher quality materials. +1 die size per 100 obols.
Knowledge: If you have access to a library, roll 1d6. Adjust die size by Intelligence Modifier.

ie. Joe Average the Wizard has access to a library and isn't bothering to spend extra time. He rolls 3d6.
Smarto Richpants the Mage is in a town with no library but pays 300 obols for premium materials, and he's got a +3 Int Mod. He rolls 1d6+1d12 since the Quality is higher but without a library he can't put his superior intellect to use.

Roll and look up the result on the relevant table.

MY POTIONS ARE TOO MUCH FOR A BEAST, LET ALONE A MAN!


Clerics

Over half the current party are Clerics, to my delight. They're very very powerful and have some fun gimmicks.
A potential issue with the well-received new Cleric rules is that Clerics lost a few of their more powerful high level spells - namely Cure Disease and Remove Curse - so these are Downtime things now. Honestly it fits better this way - Curing Disease with a snap of the fingers is a little boring.

Bless Holy Water
Gain 1 vial of Holy Water per level.
Holy Water burns unholy creatures like undead, demons and elves for 1d8 damage.
Holy Water can be stacked 5 to an encumbrance slot.

Hasten Recovery
Miraculously increase the recovery speed of a person suffering from a lingering injury.
Each Hasten Recovery ritual reduces their recovery time by one week.

Treat Disease
Alleviate the symptoms and halt the progression of all diseases afflicting a person.
At the end of the ritual they may make a Save vs Law against each disease afflicting them, curing that disease on success.

Transfer Curse
Remove a curse from a person and place it into another vessel. The vessel can be any object, living or inanimate, but it must be present for the entirety of the ritual.
If the vessel is a willing person the transfer is automatic. Else the afflicted must pass a Save vs Law to successfully transfer the curse.
If the cursed vessel is ever killed or broken, the curse moves to the one who destroyed it.

Sanctify Church
Consecrate a building or structure to become a Church of your faith.
Churches are consecrated ground and painful for wholly Chaotic beings like demons, elves and undead to enter. Such creatures cannot use their supernatural powers within the area, and corpses in the area cannot be animated.
The sanctification lasts as long as the structure is used as a place of worship, or until the Church is desecrated by destroying the altar.




Discussion

Wizards

Spells
Some mild changes here on top of the timings, most interestingly - the potential to create a sentient spell! Extremely rare if you've got access to a library, but out in the woods with the hedge witches I suppose these things must be more common...
The other downsides are to make it more in-line with the new Mana rules for wizards.

Potions
I don't have enough opportunities to give players random potions, so here's a way for players to brew their own!
Rather than something boring like "brew a single-target spell you know into a potion", this now creates a random potion, or lets you clone a potion you already have. Much improved!

Scrolls
Deciphering is a bit messy. Basically any class can use any scroll with an Arcana roll. To allow MUs to use MU scrolls and Necros to use Necro scrolls without risk, successfully identifying a scroll means you can cast it without risk if it's on-type for your magic.
Full text for identifying scrolls and wands -
Roll Arcana. On success, you identify the spell. 
You also Decipher it if your character class can cast it. You can use Deciphered Spellbooks normally, and cast from Deciphered scrolls as an Action.


Clerics

Holy Water
Clerics can create holy water for free now! Good for fighting demons and elves and undead, so on-brand for Clerics.

Hasten Recovery
With the new Cleric comes the loss of classic Cure spells in favour of a healing pool mechanic. This does mean that there's no Cure Critical Wounds to heal a broken arm or something, so we've got this activity instead.
A team of Clerics healing one person seems pretty Christ-like. Maybe the disciples were Clerics too?

Treat Disease
A classic Cleric job, but in downtime form. Not much more to say really.

Transfer Curse
I never liked that Clerics could just cure a curse. Curses are fun!
So now there's this, which means a curse must be transferred to some other vessel.
The classic Levitican trick of a Scapegoat will totally work though!

Sanctify Church
A fun one because my campaign is going to have a through-thread of spreading across the world and repopulating it, chiefly by settling new towns in the horrible poisoned wastes. New towns need new churches, and this is how to make them!

Post-Apoc Fantasy Hexcrawl Rules

The end of the world dragged my campaign kicking and screaming from a civilised network of roads and cities to a proper hexcrawl across the barren earth.

This is an awful, painful place to travel through. The air burns to breathe, the rain is acid, and the threat of a Gas Front rolling through and vapourising all organic life is ever-present.
It's harsh, it's slow, and it's draining, but looting the ruins of the old world is an extremely profitable line of work...

Intent

Harsh
Travel in the post-apocalypse is dangerous due to the harsh environment and the toxic weather.
Almost everything is dead out there, so the classic travel danger of creature encounters is replaced with more impersonal forces like horrible rain or choking mists.
These rules are meant to refocus my campaign so that travel itself is part of the meat of the game, something players have to think about and plan around, rather than just a time tax between destinations.

Slow
Travel in the post-apocalypse is slow. Roads are old and ruined, towns have fallen into decay, and travel is physically exhausting. Gone are the days when you could zip across the regional map in less than a week by road, we're in the Post-Apocalypse now.
I like the idea that my well-used map effectively changes scale without changing size. Quick trips taken by road or by air in the past will now take several days, and it will be a logistical challenge to carry all you need to survive without slowing yourself down.

Exploratory
A game set in a relatively civilised area of towns linked by roads is tacitly a pointcrawl. You travel between destinations by road and rarely trudge through the wilderness.
Not so in the post-apocalypse. Now we're in a proper hexcrawl, and that means exploring!
Nobody really knows what's out there any more, but there are old maps and memories of the old world (even for the players, who have "lived" in this world for years).
The players are now explorers, pioneers, and treasure hunters in a world they once knew. It's pretty cool!

Extent of player exploration to date

Base Units

Distance
Distance is measured in Miles.
The world is divided into 1 mile Hexes.

Time
Overland time is divided into Watches.
Each Watch is approximately 4 hours of activity.
6 Watches per 24 hour period.

Basic Procedure

Each Watch follows these steps -
  1. Group Up: If they wish, the party can form into separate groups.
  2. Choose Activity: Each group decides what they're doing this Watch
  3. Lost: If outfield, the DM secretly checks to see if each group is lost.
  4. Encounters: Roll and resolve encounters per group. 1d6 if outfield, 1d12 if encamped.
  5. Weather: Resolve weather effects.
  6. Activity: Resolve the activity itself per group.

Where would we be without laminated gimmick sheets?


Previous laminated gimmick sheet in action. This is Winter, so the day only lasts 2 Watches / 8 hours.


Travel

This is the main thing with hexcrawl rules so I'm putting it first!

Maximum Travel Distance
On foot, your speed is limited by your Encumbrance.
I'd probably double these for pre-Apocalypse travel.

EncumbranceMiles/Watch
Unencumbered4
Lightly3
Heavily2
Morbidly1
Over0

Exhaustion
This is one of the main limiting mechanics to travel.
Each point of Exhaustion gives you a -1 penalty to all ability score modifiers and counts as an Oversized item (ie. +1 Encumbrance), slowing you down.
If it's been over 4 Watches (16 hours) since your last Rest, you take 1 Exhaustion per Watch.
Weather also commonly builds up Exhaustion, eventually forcing you to stop and rest.

Trails
You can intentionally leave a Trail as you travel.
This gets added to the map, making it easier to backtrack and easier to take the same route at a later date.
There might be times when you don't want to leave a Trail (like if someone's tracking you), but most of the time you'll want to leave one.

Travel by Vehicle
See the rules for Vehicles at the bottom of the post.
In short - vehicles are great for carrying stuff and protecting occupants from the weather, but they're liable to crash off-road. Wagon trains encouraged.



Watch Activities

Some examples of things you can do in one Watch.
Encounters are rolled on an encounter grid (see Encounters section below).
Encounter chances are effectively halved when you're encamped.

Outfield Activities
Basically any activity where you're moving around in the open exposed to the elements.
Encounter severity is rolled on 1d6.

Suggestions include:
  • Travel: See Travel section above.
    Basically just move as far as you want up to your group's maximum travel distance.
  • Explore: Search a hex for things of interest.
    No need to roll, you just find anything in the hex by the end of the Watch.
  • Forage: Search for sustenance.
    See Foraging section below.
Encamped Activities
Basically anything you want to do that doesn't involve leaving an immediate area.
It probably goes without saying that anyone at the same campsite is in the same group for encounter purposes.
Encounter severity is rolled on 1d12, with results 7-12 as "nothing happens".

Suggestions include:
  • Set Camp: Set up tents and organise the camp site, ie. draw the map of the camp.
    Important if some sort of post-apocalypse beast comes sniffing around.
    Shielded Camps: Some hexes have protected campsites that are good enough to resist deadly Gas Fronts and other dangers. Resist all weather effects, and when Encounters are rolled you can replace the result with "nothing happens" if you wish.
  • Cook Food: As per the Dungeon Masterchef post.
    We've seen multiple cookoffs so far, which pleases me greatly!
  • Forecast: Check to see where the weather's heading.
    Roll Bushcraft. On success, you can tell what the next weather change will be.
    On failure, you at least know the possibilities.
  • Rest: See Getting Some Rest section below

Foraging

It might look like everything's dead out there... but if you know where to look you'll find some strange edible flora and fauna that's managed to adapt to the toxic atmosphere and frequent all-devouring Gas Fronts.

Forage
Roll a Bushcraft group check (ie. use highest Bushcraft score in the group).
On success, find 1d4 Ingredients +1 per additional forager.
The Ingredient you find is based on terrain. Roll 1d10 on the associated Forage table to see what you find!

***PLAYERS DON'T CLICK***
You can find my current (incomplete) Forage tables in this sheet. It's all weird stuff adapted to the post-apocalypse, so you'd want to change it to Nettles and Mushrooms and stuff for non-fucked settings.
***THANKS FOR BEING GOOD!***

Set Forage
The first time Forage is found in a hex it becomes easier to find that particular Ingredient there. Set Forage by adding the Ingredient to the hex description.
Any time that hex is successfully foraged in the future, the forager rolls the 1d10 and can choose between that and the Set Forage.
Really good if you know you need a certain foraged ingredient for a particular meal!

Weather Boost
Each type of Forage is more prevalent during certain weather (see Weather below).
During the right weather, boost the Ingredients roll twice - from 1d4 to 1d8.

Example for Hills areas. If you want Popjack, go out during a Haze!
Season
In Winter, find 1 Ingredient per forager in the group only.
I was considering having proper seasonal forage, but it's easier to just add some seasonal flavour to the description. Plus that'd be a lot of backend work to track forage per hex per season!



Getting Some Rest

Sleeping out in the wastes is hard when you're plagued by itches and your mate's coughing up a lung on the bedroll next to you. Luckily you're often so tired that you don't care.
Going more than 4 Watches without a rest gives you one point of Exhaustion per Watch.

Shelter
Scratch-built shelter won't do in the post-apocalypse. You need a proper Survival Tent!
Costs available here.

Rest
Resting for a single Watch heals 1 point of Exhaustion.

Long Rest
Resting for two Watches in a row cures all Exhaustion.
You get Overnight Healing rates as per the house rules.
In short:
- No Food and/or Shelter: If you're on 0HP, no healing. Else heal your Bushcraft score in HP.
- Food and Shelter: Heal up to the next step of Half HP, Full HP, or Full+1d6 HP.

Convalescence
Resting for a whole 24 hours (6 Watches in a row) with food and shelter heals ability scores.
Save vs Doom. On success, heal 1 point of stat damage in all affected ability scores.


Getting Lost

It's fairly easy to lose your way if you're not following a trail, especially with the terrible weather and the way the air stings your eyes. I cannot emphasise enough how much the post-apocalypse sucks.
The base chance of getting lost while outfield is 1 in 6, adjusted by the following modifiers:

Getting LostModifier
Following Road/River-3
To Visible Landmark-2
Following Trail-1
Following Map-1
Clear Weather-1
Hazy+1
Rainy+3
Foggy+5
Night (Bright Moon)+1
Night (Quarter Moon)+3
Night (Dark Moon)+5

If a group gets lost while travelling the DM secretly rolls on this chart to see which way they went. They leave their intended path at a random point in the journey.
If they get lost while exploring or foraging within a hex, they simply end up in a random hex nearby.
A lost group makes a Bushcraft group check (ie. use highest Bushcraft score).
On success, they know their bearing, how far off course they are, and the direction of their intended destination. On failure they've got no idea.
Groups that left a trail behind them could retrace their steps, those who don't might be in trouble.

Encounters

Overland encounters use an encounter grid as per that post.
Encounter severity roll depends on whether the group is Outfield or Encamped.
1d6 for Outfield.
1d12 for Encamped.

Encounters with actual creatures are rare, so they're on the low and high ends of the bell curve.
The special part is that there are common entries that change based on terrain, weather and hex.

***PLAYERS DO NOT CLICK***
You can check out the encounter grid I'm currently using here.
***PHEW THANK YOU THAT WAS CLOSE***

Base results are these, so I can explain the special non-creature ones.

    Probability fiends will note that there's only a 33% chance of an encounter involving a creature.

    The environmental "encounters" are these:
    • Weather Effect: Doubles down on weather effects, no matter the weather.
    • Terrain Special: Changes based on terrain, so Hills is different to Plains and so on. Sometimes cause something to be added to the map, like a new fissure appearing in a Hills area.
    • Hex Special: Involves the current hex they're in.
    • Weather Special: Changes based on weather, so Haze is different to Acid Rain and so on. Usually additional badness, but sometimes something nice happens like the rain lets up for a bit!
    • Rogue Weather: The weather changes! This is temporary and the weather has turned back by the end of the Watch. If the party splits up and multiple groups get different Rogue Weather I guess the results are strangely localised.
    The effects change with the severity roll. You can see the effects on the encounter grid linked above.



    Weather

    Since it's after the end of the world there is now a massive focus on environmental dangers, chiefly the weather. Plus complaining about the weather brings us together as Englishmen.
    The stinging Haze leads onto Acid Rain or thick Chokestorms, and deadly Gas Fronts are an ever-present threat. Thank goodness the Gas Fronts are usually preceded by the crackling electrical storms of the Warning so people know when to get to cover. And all that's just in Spring!

    ***PLAYERS DO NOT CLICK***
    Weather types as of right now can be found here.
    ***CHEERS!***

    Survival Gear
    It's awful out there. You need protective clothing and a breather mask to last long out in the wastes.
    Survival Gear replaces normal armour and follows the same rules (see house rules).
    Short version - Certain effects can Notch your armour, each Notch reducing its AC by 1. If this ever makes it worthless, it falls apart and is irreparable.
    Filter Masks replace Helmets. They can be destroyed by certain Death and Dismemberment effects.
    Six-Dimensional Weather
    Invented by Daniel Sell at What Would Conan Do, this hex-based Six-Dimensional Weather is the foundation of this weather system. You can see how it works at that link. It's very clever!



    Types of Weather
    There are six types of weather. Each season has a variation on the theme.
    • Haze: Common travelling weather. Fair visibility, but exhausting to walk in.
    • Acid Rain:
      Heavy rain that eats away at your gear. Bad visibility.
    • The Warning:
      Precedes Gas Fronts. Lightning storms that are safe to walk in unless you clash metal on metal.
    • Gas Front:
      Lethal fog of Omnipoison converts all organic life it touches into more Omnipoison. If you're lucky you die instantly.
    • Clear:
      A rare reprieve from the weather!
    • Storm:
      Seasonal variation, always terrible. Usually a worse version of the Haze with bad visibility.
    Weather Change
    Weather moves around the hex map every dawn and dusk.
    When the weather changes, roll the next change in advance so players can Forecast it.

    Weather Effects
    Each type of weather has an associated Effect.
    If you're not wearing survival gear and a breather helm, you also take the Exposure effect. Somehow despite wearing practically nothing, Barbarians always count as wearing survival gear and breather helm.
    If combat occurs, Encounter Conditions apply.
    For example these are the Weather possibilities for Spring. You'll notice pretty much everything sucks. That's the post-apocalypse for you!


    Forecasting
    An Encamped activity.
    Roll Bushcraft.
    On success, you know what the weather will be next time it changes.
    On failure, you at least know the potential options.

    Fast Forwarding
    If you ever need to fast forward the weather, like if players are resting up safely in town for a while, just roll a weather change twice per week.
    It's assumed that the random walk did a completely average return-to-origin loop for 6 days, then went somewhere else on the 7th day.
    If I had a computer program that could do it for me I'd use that though!


    Seasons

    Seasons change over the course of the campaign, especially since I'm intentionally pushing the timeline forward by limiting the PCs to one Expedition or Downtime activity per in-game month.

    Weather
    Each Season has a different spin on the basic weather types (see that section above) and a different feel.
    • Spring sets the standard. Variable levels of crap weather. Relatively rare Gas Fronts but potentially interminable Chokestorms might stop travel for days.
    • Summer has long stretches of clear days, but if it gets bad it tends to stick. Hot weather is exhausting for anyone in heavier gear.
    • Autumn is all wet and miserable. Rain tends to last, alternating between acid rainstorms and an interminable hissing rain that makes it easy to get lost.
    • Winter is brutally cold. Travelling requires you to have Cold Weather Gear - an Oversized item - lest you freeze to death. At least Gas Fronts freeze into the ground in winter.
    Day Length
    The day gets longer and shorter over the course of the year.
    Your chance of getting lost increases at night (see Getting Lost section above).
    Watches from dawn until dusk:
    • Summer: 4 Watches
    • Spring/Autumn: 3 Watches
    • Winter: 2 Watches



    Travel by Vehicle

    Finally, travel by Vehicle!
    This ties in better to the roads in the seasonal Rebuild Phase (to come) but the travel stuff is relevant.
    While vehicles have the potential to be slightly faster than a party on foot, they're mostly about carrying supplies and/or protecting occupants from the weather.

    I'm pretty pleased with the speedometer gimmick!
    Compartments
    Vehicles have 6 Compartments - numbered 1-6 in the image above.
    A compartment can fit one person and all their equipment, or 20 encumbrance slots-worth of items.
    If you got a good treasure haul you might have to walk because your wagon's full of stuff.


    Speed
    When you Travel with a vehicle, choose how fast you're going.
    Higher speeds increase your chance of crashing, as per the image above.
    You'll notice that this is slow, but that's because the roads are real bad. If you were driving down a maintained and paved road you'd go at double speed, but no roads are that good just yet!

    Crash Chance
    Base 1 in 6 with the following modifiers.

    Crash ChanceModifier
    On road-3
    On trail-1
    Off-road (flat)+2
    Off-road (rough)+4
    Clear Weather-1
    Hazy+1
    Rainy+3
    Fog+5
    Night (Bright)+1
    Night (Quarter)+3
    Night (Dark)+5

    If you crash, the driver will roll on the Vehicle Crash Table.
    They make a Piloting check.
    On success they roll a 1d6 on that table. On failure they roll 1d12.
