POWER CRIT

You may threaten a critical hit if you succeed in hitting an opponent.
Prerequisite: Base attack bonus +10, proficiency with weapon.
Benefit: You may spend an action point before making an attack with a weapon with which you are proficient. If the attack hits, it automatically threatens a critical hit (regardless of whether the attack roll falls within the weapon's actual threat range). You must roll to confirm the critical hit, as normal. This is a supernatural ability.
Normal: You must roll in the threat range of a weapon, then confirm that threat to score a critical hit.
