Structure

This page details military structure of Chaos Daemons forces including Detachments, Formations and Apocalypse Formations.

Detachments


Daemonic Incursion

A Daemonic Incursion allows you to represent the typical structure of a Chaos Daemons army on the Warhammer 40,000 battlefield. Whether you wish to represent a full-scale daemonic invasion or a more localised Warp breach, the choices below offer a great way to pick your army.

A Daemonic Incursion is a special type of Detachment that can be included in any Battle-forged army. Unlike the Detachments shown in Warhammer 40,000: The Rules, it has a Force Organisation Chart whose slots are a combination of specific Formations and Army List Entries instead of Battlefield Roles. However, it still has compulsory and optional elements, as well as Restrictions and Command Benefits, just like any other Detachment.

Although units cannot normally belong to more than one Detachment, units from a Formation that is part of a Daemonic Incursion are an exception. They count as part of both their Formation and the Detachment, and have all associated Command Benefits and special rules. If your Warlord is part of a Formation or an Army List Entry that makes up part of a Daemonic Incursion, that entire Daemonic Incursion is your Primary Detachment.

THE HUNTER OF KHORNE
 • 1 Karanak

RESTRICTIONS
This Detachment must include at least one Core choice and one Auxiliary choice. It may include up to four Command choices and any number of additional Core or Auxiliary choices, in any combination. Only the datasheets listed here can be included in this Detachment.

COMMAND BENEFITS
Daemonic Corruption: Any Objective Markers controlled by units from this Detachment at the end of your turn count as being under your control for the rest of the game, even if you have no units within 3" of them. A unit can only corrupt a single Objective Marker in this manner at the end of each of your turns. This effect lasts until an enemy scoring unit cleanses the objective by controlling it.

Patronage of the Dark Gods: Psykers from this Detachment can choose to generate all of their psychic powers from the Discipline of Change, Plague or Excess (as appropriate) if they wish. However, if they do so, then the rules for Chaos Psychic Focus (see Warhammer 40,000: The Rules) no longer apply to them; they follow the normal rules for Psychic Focus instead.

The Warp Unleashed: You can choose to re-roll any Daemonic Instability tests for units from this Detachment.

Unearthly Power: When rolling on the Warp Storm table, you can choose to add or subtract 1 from the result.

Formations


Burning Skyhost

FORMATION
 • 1 The Blue Scribes or Herald of Tzeentch
 • 9 units chosen in any combination from the following list:
  - Screamers of Tzeentch
  - Burning Chariot of Tzeentch
SPECIAL RULES
Harbinger of Tzeentch: If the Herald of Tzeentch from this Formation is a Lesser Locus of Transmogrification, Greater Locus of Change or an Exalted Locus of Conjuration, the special rules associated with that locus affect all units from this Formation that are within 12" of him. If such a unit is also affected by another locus, they will receive both benefits.

Trail of Transmuting Flame: If a Burning Chariot of Tzeentch from a Burning Skyhost moves Flat Out, pick an unengaged enemy unit it moved over. That unit suffers D6 Strength 5 AP4 hits with the Soul Blaze and Warpflame special rules. Use the final position of the Burning Chariot for the purposes of determining Wound allocation; vehicles are always hit on their side armour.

Furthermore, Screamers from a Burning Skyhost cause D3+1 Strength 4 AP`-` hits when making a Slashing Attack rather than D3 hits. These attacks also have the Soul Blaze and Warpflame special rules.

Warpflame: At the end of each phase, any unit that suffered one or more unsaved Wounds during the phase from an attack with this special rule (or from an attack made by a model with this special rule), must take a Toughness test. If the test is failed, the unit immediately suffers D3 Wounds with no armour or cover saves allowed. If the test is passed, all models in that unit gain the Feel No Pain (6+) special rule for the rest of the game. Any models in the unit that already have the Feel No Pain special rule instead gain +1 to all Feel No Pain rolls for the rest of the game. Chaos is fickle!

FORMATION

Harbinger of Slaanesh: If the Herald of Slaanesh from this Formation is a Lesser Locus of Grace, Greater Locus of Swiftness or an Exalted Locus of Beguilement, the special rules associated with that locus affect all units from this Formation that are within 12" of her. If such a unit is also affected by another locus, they will receive both benefits.

Gorethunder Battery

SPECIAL RULES
Harbinger of Khorne: If the Herald of Khorne from this Formation is a Lesser Locus of Abjuration, Greater Locus of Fury or an Exalted Locus of Wrath, the special rules associated with that locus affect all units from this Formation within 12" of him. If such a unit is also affected by another locus, they will receive both benefits.

Skullrain Salvo: All of the Skull Cannons in a Gorethunder Battery must be fielded as a single vehicle squadron. Whilst this Formation includes three Skull Cannons that can fire, the squadron can fire a single Skullrain Salvo instead of firing normally. To do so, nominate one model in the squadron as the firer and use the following profile:

If such a unit is also affected by another locus, they will receive both benefits.

If the test is passed, the directed unit can re-roll failed charge rolls and all models in the unit can make 3 additional Attacks until the end of the turn; if the test is failed, the directed unit must attempt to charge the nearest enemy unit in this Charge sub-phase, but is otherwise unaffected.
