Breath is a Special Attack which can only be used once during the game. If a model has more than one Breath, it can only use one Breath in a single phase. It can be used either as a Shooting Attack with Range 6″ (may March and Shoot) or as a Melee Attack at the model’s Agility (declare the use at the start of its Agility Step).
Breath causes D6+3 hits at the Strength and AP as indicated in parentheses.
