Infernal gateway

The psyker opens a portal to the warp, a tear in the
fabric of the mortal plane that sucks foes into certain oblivion.
If manifested, identify the nearest enemy model
that is within 12" of the psyker and visible to him
that model's unit, and every other unit (friend or
foe) within 3" of that model, suffers D3 mortal
wounds. The number of mortal wounds inflicted
is D6 instead if the power is manifested with a
Psychic test of 12+.
