The Wraithguard, once living Eldar soldiers, have escaped death through preservation in spirit stones. It is these spirit stones which guide their Wraithbone constructs, a powerful material which is used in the construction of the devastating yet swift Eldar tanks.
The Wraithguard will be a Tier 2 heavy armor infantry unit for the Eldar. While they look similar to the Wraithlord, they are much smaller in size, and wield a portable version of the D-cannon, known as the Wraithcannon, a powerful but short ranged weapon.
Upgrades and Abilities:WarlockAdd a Warlock to lead the squad. Warlocks have Wraithsight which boosts the speed of nearby Wraithguard.
WraithboneGrants the Wraithbone ability, allowing Wraithguard to regenerate health (while immobilizing the unit). Requires Tier 3.
The Wraithguard looks to be a formidable unit in the upcoming
Dawn of War II: Chaos Rising expansion.
