Grabbing Master

Combat

You can grapple two foes as easily as one.

Prerequisite: Grabbing Drag†, Grabbing Style†, Improved Grapple; base attack bonus +12, brawler† level 8th, or monk level 8th.

Benefit: When you are grabbing two opponents while using Grabbing Style, you can use your grapple to move or damage both opponents you are grappling, instead of just one.
