Storm of Force
The psyker has developed his powers to the furthest reaches. He can generate a rain of force bolts that can smash his enemies in a savage storm of psychic fury. The psyker can pick out a number of targets equal to his psy-rating for each round that he maintains this power. The psyker must make a ballistic skill test to hit each of the targets, and deals 2d10 impact damage with a bonus of +2 damage per psy-rating. No target may be hit more than once a round.
