Warhammer/Tactics/6th Edition/Chaos

Why play Chaos

To crush your enemies; to see them driven before you; to hear the lamentations of their women.

The forces of Chaos - divided into two army books, Hordes of Chaos and Beasts of Chaos, but written to work as a pair - are savage, brutal, unforgiving barbarians, plus twisted-up gnarly mutants and eldritch monsters from another dimension. It is an army raised for a single purpose: to destroy the world of men (and elves, and dwarfs, and even goblins and especially lizards, although rodents of unusual size may be all right).

In battle, the Chaos army is a relentless melee death machine, forsaking any ranged attack that isn't "throw a melee weapon at someone" or "bind an eldritch horror into a cannon the size of a house and fire it when you want to move castles out of the way". Some Chaos armies opt for weight of numbers, drowning the foe in a sea of low-cost light infantry; others go for the small force of elite hard-cases wrapped in nigh-impenetrable armour. Chaos has access to powerful, aggressive magic to ease their passage across the field, and a wide variety of fast-moving "chaff" units to distract and harry the enemy, but make no mistake: sooner or later, this army is about bringing axe to face and making damn sure it stays there.

Army Special Rules

Daemons, Mortals and Beasts

Most Chaos units are classified as either Daemons, Mortals or Beasts. If your General is a Mortal, Mortal units are your Core units, while Daemons and Beasts are Special. If your General is a Beast, Beast units are your Core units, while Mortals and Daemons are Special. If your General is a Daemon... you get the idea. Just to complicate things further, some units (mostly Rare, but one or two Specials like Chaos Trolls and Chaos Ogres) always stay in the same category no matter who's in charge.

Marks of Chaos

Many Chaos units and characters have Marks of Chaos. The default is the Mark of Chaos Undivided: all units which can have a Mark start off with this one, and it's free. You can choose to dedicate your units to a particular Chaos God and gain upgrades, for a few (or more than a few) extra points. The Marks do different things depending on the model they're applied to, and we'll get into the specifics of those later. The important thing for the army is that if your General has a particular God's Mark, all your troops who can have a Mark must have the same one, or stick with Chaos Undivided. If your General has the Mark of Chaos Undivided, you can go hog wild with the rest of your units and characters.

Daemonic

Some Chaos units are not of this world. Daemon units all cause fear, and the big 'uns cause terror as well; they are immune to psychology; they have a 5+ Ward save which applies to everything except magical attacks; they count as having magical attacks themselves; and they have Instability.

Instability is a fiddly rule that comes into play if your Daemon unit loses a round of combat. Once you know they've lost, take a Leadership test on their unmodified Leadership stat: if they fail this, they disappear, vanish into the Realm of Chaos in a huff. THEN take the same roll and compare it to their Leadership stat as modified by combat resolution, and inflict that many unsaveable wounds on the unit.

Oh, and Daemon characters can't join non-Daemon units, or vice versa.

Ambush

If your General is a Beast with the Ambush rule, Beast units with the Ambush rule can move on from a table edge instead of deploying normally. You can Ambush in any battle where you're allowed to use Scouts. Up to half the eligible units in your army (rounding down) can Ambush, and your General has to start the game on the board. Units in Ambush aren't in play and don't generate Power or Dispel dice, so keep your wizards on the table.

Starting from the second turn, in the Remaining Moves phase, you can bring your Ambushing units on. They have to come on all at once. For each unit, one by one, pick a point on any table edge: that's where they should be. Then take a Leadership test for the unit. If you pass, they move on from that point as if they've returned from pursuing an enemy off the board. If you fail, roll a Scatter die in the middle of the board and follow the arrow to the edge: that's where they turn up instead. (Don't forget that there's a little arrow on the HIT faces for exactly this kind of situation.)

Marks of Chaos

Who Gets 'Em?

• Daemons - Daemon Princes and Exalted Daemons
• Mortals - Lords and Sorcerer Lords; Champion and Sorcerer Heroes, Warriors, Chariots and Knights
• Beasts - Beastlords, Great Shamans, Doombulls and Dragon Ogre Shaggoth Champions; Chieftains and Shamans; 1 and only 1 Bestigor unit; Minotaurs

Mark of Chaos Undivided

The default option, totally free, and not to be sneezed at, this Mark offers a reroll on all psychology tests (that's fear, terror, panic, controlling your frenzy, but NOT Break tests for losing combat). Chaos armies have pretty average Leadership on the whole, with Warrior units a bit better and Beast units generally worse. They also tend to take quite a few Panic tests as the first few turns are a slog across the battlefield getting shot at on your way into melee. While other Marks allow you to dominate whole phases of the game, they get expensive fast, and if you want a proper ravening horde, sticking to Chaos Undivided is a good option.

Chaos Spells

Wizards with the Mark of Chaos Undivided get access to Death and Shadow magic, plus Fire (Mortals and Daemons) or Beasts (Beasts). Shadow magic is probably the pick of the pack here, with Unseen Lurker and Steed of Shadows to accelerate your movement into combat. Fire does a fine job of compensating for your lack of conventional ranged firepower, and the Flaming Sword of Rhuin is a great spell to draw on your Daemon Prince or Exalted Daemon. Death is merely OK, and Beasts highly situational with a few too many spells that rely on your opponent having brought the right models to cast them on.

Lore of Tzeentch

Tzeentch spells are all about doing damage, or preventing damage - oddly enough, the real moustache-twirling nyahahahahajustasplanned stuff is more Slaanesh's remit. Notably, this lore has seven spells: any wizard can trade out a spell they don't want for Red Fire of Alteration, which you can't roll up at random because you can't roll a 0 on 1d6. (Note that because of the way 1d4chan's code handles numbered lists, it's at 7 on our summary, which of course breaks the rainbow theme GW were going for.)

1. Orange Fire of Protection - cast on a 6+, remains in play, reroll any of the Sorcerer's to hit, to wound or to save rolls that you don't like. (Just the Sorcerer: not anything they're riding.) Actually pretty good: an easy cast, and Tzeentch Lords or Heroes can throw down in combat with the best of them.
2. Yellow Fire of Transmutation - another 6+ cast that remains in play, this one granting a 5+ Ward save to the Sorcerer, their mount, and any unit they joined. Notably, this one replaces the Daemonic Ward, allowing Tzeentch Daemon characters to stop worrying about magic weapons.
3. Green Fire of Mutation - a 9+ cast on an enemy unit that's not immune to psychology, which makes it play "stop hitting itself" for a turn: the unit fights a round of close combat against itself and takes a Panic test if enough casualties are inflicted. Some armies hate this - Lizardmen spring to mind, as their best fighters have multiple attacks but rely on Cold Blooded rather than full on immunity to psychology. Others, like Vampire Counts and Tomb Kings, don't give two tugs.
4. Blue Fire of Metamorphosis - another 9+ cast for a dubiously reliable magic missile. 2d6 hits is good, Strength d6+1 is untrustworthy. Conventional Lores often give you an 8+ for a Strength you can rely on. Warp Lightning this ain't.
5. Indigo Fire of Change - on an 11+, every model in the target enemy unit takes a S2 hit, and any that die turn into Horrors, placed in contact with the front of the target unit and counting as having charged! This one's psychologically damaging to say the least: while Horrors aren't up to much in a scrap, they can take on anything that dies from a S2 hit. Big units of lightweight troops will tremble at the dubious prospect.
6. Violet Fire of Tzeentch - 12+ cast, 6" range, single target model takes a Leadership test or DIES. No saves, no regenerating, no nothing. Given how easy it is for Tzeentch casters to fly, the short range isn't the drawback it usually is. This one's a gamble, but considering that it can snipe characters regardless of line of sight, being a unit, monstrous mountage, ANYTHING, it's worth a cast. If you're going terror-bombing with a Lord of Change or a Sorcerer on a Dragon, lead in with this horrible thing - cast it on your enemy's General and potentially watch their army crumble next turn.
7. Red Fire of Alteration - I am fate, come round at last; I am also a mediocre magic missile, only a 5+ cast and with d6 hits at d6 Strength. All the usual problems of a d6 hits magic missile and you can't even count on the Strength. Swap it out for something a level 2 wizard simply can't cast, but don't expect it to do anything. Fire and Death have better equivalents and Shadow's Creeping Death knocks it into a cocked hat because NO ARMOUR SAVES.

Tzeentch wizards will often have access to a giant pool of dice from all their Marked units, especially in Mortal armies, but don't think you have to go big or go home. A pure Marked Tzeentch army may have a lot of Power dice to throw around, but it'll be light on numbers (as none of the cheap bodies can carry the Mark) and have no resilience against psychology, crumpling to a run of bad terror or panic tests (which you'll be taking a lot if you've loaded up on small Marked units to spam dice). Chariots are a really good way to sneak a few extra power dice into your army, make sure all your wizards have enough to cast at their full potential if they need to, and then fill out on solid Undivided bodies or Marauders to give your casters the meatshields they need to get the job done.

Tactics

AMBUSH!

The Beastman Ambush is a bit of a gimmick as, all else being equal, your Beast Herds will probably be doing the Ambushing and they only turn up where you want them slightly more than half the time. Nevertheless, it can work very well provided you stick to small Herds, with Warhounds on the table at the start, to fill up your Core slots, and then use your Specials for some more reliable troops (Chaos Warriors) to force engagements which the Beastmen then tip in your favour.
