Legiones Astartes (World Eaters)
Unit with this special rule may always attempt to regroup regardless of casualties.
Incarnate Violence: All units with the Legiones Astartes (World Eaters) special rule gain the Furious Charge special rule once they have destroyed a unit in close combat or caused a fall back after a victorious Assault Phase.
Bloodlust: after winning an assault, models with this special rule must always consolidate towards the nearest enemy unit they have the ability to harm. Should a unit with this special rule fail a Morale test after being defeated in combat, before roll to fall back, roll a D6. On a roll of 6 they do not flee ( and count as passing their Morale test instead), but now become subject to the Rage special rule for the rest of the battle.
Legion Specific Unit
In addition to these found in the Crusade army list, the World Eaters Legion has particular access to addtional unit types: Rampager squads and additional wargear; chainaxes and gladiatorial weapons of the Gladiator for their Rampagers squad.

Any character with the Legiones Astartes (World Eaters) special rule which has access to a chainsword can instead take a chainaxe for free as long as this is appropriately represented on the model.
