Reborn Warhost

The combined forces of the Aeldari take to the battlefield as a Reborn Warhost. These warriors have heard Yvraine’s words or the call of Ynnead, and fight free from the fear of soul death. This collection of the Aeldari’s most skilled warriors is more than equal to the burden that destiny has placed upon them.

The Reborn Warhost 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 Battlefield Roles and Formations from multiple Factions. 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 Reborn Warhost 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 Reborn Warhost, that entire Reborn Warhost is your Primary Detachment.

The Reborn Warhost Army List divides the units available into several categories, according to their Battlefield Role. With the exception of the Ynnari and Black Guardians units, you must use the profiles, points costs, equipment, options, special rules and any Dedicated Transports available to each unit as described on their codex datasheet. Each entry will include an abbreviated reference to the codex where their appropriate datasheet can be found, denoted as follows:

Leader of the Reborn: If this Detachment is chosen as your Primary Detachment, you can choose to re-roll the result on the Ynnari Warlord Traits table.

Our Souls We Entrust: Units from this Detachment have the Stubborn special rule. In addition, if a unit from this Detachment is within 7" of another unit from this Detachment, it does not have to take a Morale check when it loses 25% or more of its current models during a single phase (measure the distance at the end of the phase).

Warhost of Ynnead: If this Detachment includes 7 or more units, you can select one additional unit to make a Soulburst action each time a unit is destroyed.


Aeldari Bladehost

 • 2 units of Wyches
 • 2 units of Storm Guardians or Black Guardians
 • 2 Troupes
United in Death: Before choosing a unit from this Formation to make a Soulburst action, you can declare that the whole Formation is United in Death. If you do so, the Soulburst action you choose applies to all units from the Formation. You may only use this ability once per turn, and only if no unit from this Formation has made a Soulburst action this turn.

United in Life: If, at the start of Fight sub-phase, two units from this Formation are locked in combat with the same enemy unit, they gain the Hatred special rule until the end of the phase. If three or more units from this Formation are locked in combat with the same enemy unit at the start of the Fight sub-phase, they also gain the Preferred Enemy special rule until the end of the phase.

Soulbound Vanguard

 • 2 units of Dire Avengers
 • 1 unit of Incubi
 • 1 unit of Wyches
Chosen Warriors: While a unit from this Formation is joined by the Visarch and/or Yvraine, add 1 to the Weapon Skill and Ballistic Skill characteristics of the models in that unit. This bonus does not increase the characteristics of the Visarch or Yvraine.

First of the Reborn: Units from this Formation can make a Soulburst action if they are within 14" of a unit that is destroyed, rather than 7".

The Vigour of Old: While a unit from this Formation is within 7" of another unit from this Formation, it has the Furious Charge special rule.

Triumvirate of Ynnead

 • Yvraine
 • The Visarch
 • The Yncarne
Heralds of Rebirth: Friendly non-vehicle units from an Ynnari Formation or Detachment that are within 12" of two models from the Triumvirate of Ynnead have the Fearless special rule. Whilst all three models from this Formation are on the battlefield, all friendly units with the Ynnari Faction on the battlefield have the Fearless special rule.

Ynnead’s Chosen: If all three models from this Formation are on the battlefield, you can add 1 to any rolls made for the Avatar of Ynnead, Champion of Ynnead and Herald of Ynnead special rules.

Whispering Ghost Hall

 • 1 Farseer
 • 1 Shadowseer
 • 1 Spiritseer
 • 2 Wraithlords
 • Any 3 units chosen from the following:

Ynnead’s Net

 • 1 Warlock Conclave
 • 1 unit of Wind Riders
 • 1 unit of Reavers
 • 1 unit of Skyweavers
The Warlocks of the Warlock Conclave must all be upgraded to Warlock Skyrunners.
Acolytes of Ynnead: Whenever a unit from this Formation destroys an enemy unit, or is itself destroyed, put a dice to one side until your next Psychic phase. In your next Psychic phase, the Warlock Conclave generates an additional Warp Charge point for each dice set aside in this way.

The Net is Cast: All units in this Formation must be set up in Reserve. Make a single Reserve roll for the Formation in each of your turns from the second, which you can choose to re-roll. When this Formation arrives from Reserve, each unit moves onto the table as described for Reserves, except that each unit must move on from a different table edge (including your opponent’s).
