Jabbing Style

Combat Style

A cluster of quick strikes deals more damage than a single roundhouse swing.

Prerequisite: Improved Unarmed Strike; base attack bonus +6, brawler’s flurry† class feature, or flurry of blows class feature.

Benefit: When you hit a target with an unarmed strike and you have hit that target with an unarmed strike previously that round, you deal an extra 1d6 points of damage to that target.
