You gain momentum from a series of successful attacks, creating a veritable storm wind with your many strikes.
Prerequisites
Strength 13, Power Attack, Cleave, Great Cleave, base attack bonus +6.
Benefit
Each time you make a successful cleave attack, you gain a +2 bonus on weapon damage on all future cleave attacks you make as part of that action. This bonus is cumulative with itself, until you finally miss an attack, run out of attacks, or run out of enemies. Once your cleave attack ends, the bonuses is lost and does not apply to any other attacks you make that round.
