Astral blast

The psyker hurls a conjured orb of aetheric energy that erupts upon impact, blasting those nearby with a lethal psychic shock wave.
If manifested, the closest enemy unit within 9" of
and visible to this psyker suffers D3 mortal
wounds, and each other unit within 3" of that
unit suffers 1 mortal wound. The Brotherhood of
Sorcerers ability only increases the first range of
this psychic power.
