Power Blast

Gives your next ranged attack more damage, but at the cost of accuracy. On a critical hit, the target must make a fortitude save (DC of Level + 2x Dex mod) or be knocked back 5 feet (immune if larger than you). Damage goes up as it is improved. Penalty to attack will always be -3.

Level 1: Damage bonus = +3

Level 6: Damage bonus = +7

Level 8: Damage bonus = +12
