Power Attack

POWER ATTACK [General]
Prerequisite: Base attack bonus +1.

Benefit: You may accept a penalty to all your attack rolls up to a maximum equal to your base attack bonus and in exchange add the same number as a bonus to your damage rolls. This modifier remains in effect until the start of your next turn.

Comments
The original Power Attack feat doesn't function outside of melee and doubles its benefits for two-handed weapons. There's no reason for this and characters trained in martial combat should be able to use this ability regardless whether they're damage is strength-based or tactically based.
