Psychic Shriek*

Drawing a deep soul-breath, you unleash a scream that is silent in realspace but ripples through the underlying Warp with searing power, rending souls from bodies in an arc in front of you. Choose a Zone within Medium Range. Creatures (excluding you) in the target Zone and your Zone must make a Difficult (−10) Discipline (Psychic) Test Opposing your Manifest Test. If you win, the target suffers Damage equal to your Willpower Bonus plus the difference in SL, which ignores Armour. Daemons and Psykers suffer double Damage, but creatures without a Warp presence (such as Necrons) are immune to this power.
