All units in this Detachment must have the Dark Eldar Faction (or have no Faction).
During the entire first game turn, and during any turn in which the Night Fighting rules are in effect, all Troops units from this Detachment have a 5+ cover save, and all other units from this Detachment have a 6+ cover save.
If this Detachment is your Primary Detachment, you can re-roll the result when rolling on the Warlord Traits table in Codex: Dark Eldar.
