Spherical Angels and the Gods They Serve

Angels are an enemy that my players have fought quite a few times over the years.

These angels are nakedly technological - basically Modrons with a slice of Evangelion - and they're sent down by the ASE-inspired orbital gods which orbit the planet.

Here are some facts about Angels.
- They are spherical with a single central eye, and roll around in ball form when they're not in combat mode. 
- They sing to each other in Angelic Binary so fighting them sounds like fighting a choir. 
- If you kill a higher-ranked angel, one of the lesser angels upgrades to replace them.

- A full choir of them numbers exactly 21, since they are arranged with a leader Ophanim who commands four Tacticians each of whom commands four Baseline angels.
- They are part of an ancient failsafe designed to prevent the end of the world, a task they only partially succeeded at back during the Apocalypse.
- The angels are ultimately controlled by whichever God is overhead that week, and each God has their own agenda and grants the angels a different special ability.

In gameplay terms they've got a fair few gimmicks, all ultimately predictable because Law is predictable.

Mostly they scare my players because they've got good armour, magic immunity, the ranged ones have armour piercing beam cannons, and killing the leader first is a bad idea because their minions just upgrade to take their place.
That plus they usually go for Chaotic characters first, so wizards feel very victimised.

Might as well start with the stats!

I have other drawings saved somewhere but can't find them so enjoy this quick scrawl!

Stats

Angels in General

Abilities
- Immunities: Immune to Chaotic magic and stasis weaponry.
- Patrol Mode: Roll around in spherical form, mostly used when on patrol or on standby.
- Flight Mode: Can transform into a ball with wings and fly around. Can't attack in this form.
- Scan: Detect Alignment at will.

Angel - Baseline

Baseline angels are the rank and file. Four Baselines are commanded by a single Tactician.
Baselines obey orders blindly, and have no executive function of their own.
They have little skinny legs and little skinny arms and little skinny wings and basically look just like a Modron.

Stats:

HD2. AC Chain. Morale 12.
Unarmed attack: 1d6.

Abilities:

- Weapon Swap: When commanded by their Tactician, they immediately generate any kind of melee weapon. (See "Weapon Types" in the house rules)
- Upgrade: When their commanding Tactician is destroyed or upgraded, one of its subsidiary Baseline angels transforms into a Tactician. It gains +2 HD immediately.

Angel - Tactician

Tactician Angels are a real-time calculating node in the angel network. Four Tacticians are commanded by a single Ophanim. 
They have some tactical reasoning but these are strictly limited to the present moment, they have no ability for long term strategy. Mostly this is calculating stuff like "enemies are in heavy armour, use hammers" and telling their Baselines to swap to hammers.

Stats:

HD 4. AC Chain. Morale 12.
Unarmed ram attack: 1d6
or 2 armour-piercing stasis beam cannons: 1d6 each

Abilities:
- Switch Up: As an action, can order their Baseline minions to swap weapons.
- Upgrade: When their commanding Ophanim is destroyed or upgraded, one of its subsidiary Tactician angels transforms into an Ophanim. It gains +4 HD immediately.

Angel - Ophanim

Ophanim angels are the commanders of their group. One Ophanim commands 4 Tacticians that each command 4 Baselines, for a total of 21 angels per Choir.
They have the capacity for longer term strategy and are hubs for the wider angel network.
They are ultimately overseen by the Seraphim dropship that hovers at the edge of the Stratosphere.
This plus they're a whirling array of metal and high-powered beam weapons that can encase a large area within an impenetrable stasis barrier.

Stats:

HD 8. AC Plate. Morale 12.

Whirling shard attack: Attack all in 10' for 1d6 damage.
or 2 armour-piercing stasis beam cannons: 1d12 each.

Abilities:
- Reactive Movement: If hit by an attack, may take a free move without triggering Opportunity Attacks.
- Stasis Shell: As an action, create a 50' diameter shell of frozen time impenetrable to almost all non-angels. Takes a round to spin up and lasts until the Ophanim stops maintaining it. Things can still move inside the barrier, but they can't cross out and any projectiles crossing the barrier get stuck. The Ophanim itself can't act while maintaining the field, so needs to rely on its minions to destroy anything that's in there with it.

One of my players rendered one of them!

Tactics

First off, Angels hate Chaos.
They'll always attack Chaotic entities first, and will abandon their other goals until they've chased down and destroyed Chaotic targets.
They attack Neutral entities if they get too close or get in the way of their goals, but won't chase too far.
Lawful entities are ignored unless they physically attack an Angel.

Secondly, Angels upgrade.
Each Ophanim controls 4 Tacticians.
Each Tactician controls 4 Baselines.
If an angel higher in the hierarchy dies, one of their underlings upgrades at the end of the round to take their place.

Thirdly, Angels don't care about firing into combat.
All angels are immune to Stasis Beam attacks, so they'll try to get the Baselines in to tie up foes, then blast the melee with beam-fire.

Fourthly, Ophanim can use their stasis bubble for offence and defense.
If it calculates that its Choir is unlikely to survive, it can put up its Stasis Shell to prevent further action. Angels can roll through Stasis zones unhindered, so they can roll back into the field until danger has passed.
On the other hand, if it can trap a lone foe inside the field and have the rest of the angels come murder it, so much the better! This is a potentially dangerous tactic since the Ophanim can't defend itself with the field up, but mobbing one poor fool with a bunch of angels is usually a winning technique.

Gods Above

A fun extra thing about Angels is that they have different abilities depending on which God is above that week.
I track this because I have a game calendar (so cool, I know) and each week the God closest to the zenith in the skies above influences the Angels below.

You could always roll a 1d9 if you don't care about calendars.

Name	Angel Mood	Angel Special
Dispater of the Subtle Knife	Elusive	All Angels gain a free move when hit. Baselines equip reach weapons.
Oberon of the Green Branch	Wary	Baselines can use 1d6 ranged bow
Minerva of the Burnished Shield	Defensive	Baselines equip shields
The Scorned of the Rusted Blade	Resolute	Tacticians can command a weapon swap as a free action
The Dead God of the Brittle Bone	Murderous	Mob individuals. 4 in 6 Backstab.
Alaunus of the Mailed Fist	Efficient	Target lowest HP first.
The Lady of the Silver Coin	Fickle	Immune to opportunity attacks, retarget foes every round.
The Allfather of the Filled Cup	Hard-hitting	Baselines deal +1 die size for damage.
Eris of the Spinning Wheel	Hateful	Reverse priorities - kill Lawful first.

God Lore

There are, or were, Nine High Gods orbiting the Earth.
Massive mechanical minds born from aeons-ancient ingenuity, long sent into space to allow them to grow beyond all earthly proportion.
Immortal, impossible space golems, each orbit another turn of the prayer wheel.

If the Gods need to affect the world they send forth their angels.
The Seraphim, huge brass spheres, descend from above and blossom forth, the lower hemisphere opening up into six huge wing-petals covered with eyes.
Each eye is an angel, deployed from the wings according to the unknowable yet fairly obvious tactics of the Gods.

One of the Nine, Eris, was shot down in an earlier age. This has the unfortunate effect of putting angels into their failsafe "scorched earth" mode when they detect no gods overhead.

Some Faiths claim that she lies below Dwimmermount even now. Some call her Queen Satan, others believe her a fallen God unjustly wrenched from the heavens, others still say she never entered heaven at all...

Gambits! Risky Combat Manoeuvres... Now With Extra Spice!

Boy, it's been a while hasn't it? Let's get into it!

Gambits have been a mainstay of my game from the second they were introduced. Any exciting combat stuff that's not straight "roll hit, roll damage" is covered by either Gambits (roll twice, if both hit you do what you want) or a Wrestle (roll off against enemy, on success do a wrestling move).

My traditional Gambit rule, based on the Last Gasp, was essentially "declare a stunt, roll to hit twice, on double success it happens, on double fail it happens to you, otherwise we talk" situation.

The gameplay downside was that it was AC that defined whether you would successfully gambit.
A regular 1HD dude in 18AC Plate resists gambits better than a 1000000HD monster with unarmoured 12AC, that sort of thing.
It also meant that stacking to-hit bonuses would make any gambit a practical certainty, which isn't so good when Gambits can be straight up "I kill all the baddies in one move"!

The best thing about Gambits from my DM perspective is that they're always player-incited chaos, and they're always player-incited cool shit. If someone wants to Gambit they're intending to do something real cool and inviting real consequences.

So from a practical mechanical perspective, the key change is that the new formulation is based on HD instead of AC.
Weaker monsters are easier to stunt on, stronger monsters at the very least need to be taken down a peg before you break their legs.
More excitingly, as the result of a weeb fever dream, there's some extra spicy stuff to add even more chaos into the already chaotic Gambit.

The Rule

Gambit:
If you want to do something extra fancy, it's a Gambit!

Declare your Gambit, like "I want to trip them over" or "I want to chop off their head".
Roll twice against the enemy's Gambit AC. You add your Base Attack Bonus + an appropriate Stat Bonus.
Gambit AC is 10+HD. If the enemy is under half health, their Gambit AC is 10+half HD.

If both hit, your Gambit happens!
If both miss, it's an ironic reversal! The Gambit happens to you.

If it's one hit once miss, it's either a partial success or success at cost. The DM declares the options and you choose.

Example: if you said "I want to sweep their leg to trip them" against a normal 1HD mook, the DM might say that it sound like a Strength Gambit, so you roll 2d20 against Gambit AC 11, applying your BAB + Strength modifier.

You get one hit one miss. so the DM declares something like "choose: partial success means the enemy can't move next round, or success at cost means you and the foe are both knocked prone"

Gambit Specials

1 More:
If you roll a natural 20 on either die, it's a team-up attack!
Resolve the Gambit, then another character you choose can join the Gambit! This doesn't even use up their turn.
They declare a new Gambit involving the original target and roll with your original modifiers, plus their BAB plus an appropriate stat bonus.

Example: You declare "I want to sweep their leg to trip them" against a normal 1HD guard, and you succeed! One of the dice was a Nat 20, triggering 1 More!
You successfully trip the guard, and your friend says "I'm in! I want to steal her spear and chuck it at her boss".
The DM says that sounds like a Dexterity Gambit, so they roll and add their BAB + Dex mod to your original modifiers. Both hit!
You throw the guard to the floor as your friend catches her spear, and throws it like a javelin at the guard captain!

All Out Attack:
If you roll two Nat 20s on a Gambit, it's an All-Out Attack!
Resolve the Gambit, then everybody in your party (in any order, including you) gets a free auto-hit attack on the enemy of their choice! They'll never see it coming!
Movement is allowed during an All-Out Attack so long as you can justify it with a suitably cool/grandiose/ludicrous team-up combo move in the fiction.

Reversal!
If you roll a natural 1 on either die, the enemy strikes back!
Before your Gambit resolves, the enemy gets to make their own Gambit.

This is the only way an enemy can use Gambits.

Specifically:
Your Gambit AC is 10+Level.
Enemies don't usually have stat modifiers, so they only get to add their BAB.

All-Out Revenge:
If you roll two Nat 1s on a Gambit, you're swarmed!
Resolve the Gambit, then any enemy that could conceivably target you gets a free auto-hit attack on you with whatever they've got to hand!
Movement is allowed during an All-Out Revenge, so long as the DM can justify it with a suitably cinematic/tragic/bathetic scene in the fiction.

Other Issues

DM Fairness
This is probably obvious, but if one of your players rolls a Reversal you should make sure the enemy's Gambit is on par with what your player tried to do.

So if they tried something fairly harmless like trying to trip the enemy, maybe the enemy tries for a disarm or throws the character at someone else to knock them both down.
If they went for something brutal like trying to decapitate the enemy, maybe the enemy tries to chop a leg off or permanently blind the character.

Remember that your monsters are much more replaceable than PCs, so cut them at least a little slack!

Multiple Targets:
If a player wants their Gambit to affect multiple foes, just add enemy HD together to find the target number.
Like three 1HD mooks would have Gambit AC 13.
Two 6HD bears would have Gambit AC 22.
Ignore the half health thing with multiple foes, too much effort!

If a Reversal (nat 1) is rolled during a multi-target Gambit, combine enemy attack bonuses together for their counterattack.

Example: You declare "I decapitate the bears!" against two 6HD grizzly bears, and you roll a natural 1 on one of the dice! The DM says "lol ok they're going to try to rip your arms off". 
They've got +6 to hit each, so their combined bonus in their Gambit is +12 vs your Gambit AC of 10+Level.

Absolute Chaos Shenanigans:
These rules are intentionally written so that Gambits can, dice-willing, devolve into absolute chaos with a Reversal conceivably triggering 1 More triggering another Reversal and so on.

That's why I was specific about when a Gambit Special resolves! Reversal triggers before 1 More, which is especially important in the rare case of rolling a Nat 1 and a Nat 20 simultaneously.
Everything always resolves, even if some ridiculous Reversal makes the original Gambit completely implausible, so have fun working it out in the fiction!

Maffs:
For the probability wonks, every Gambit roll has approximately 20% chance to trigger a Gambit Special.
This contrasted with the 10% chance of crit/fumble on a normal attack roll.

Since Gambits tend to be less common than regular attacks, I think that's a good amount of wild card potential!
