You’ve spent time learning how to take a punch up close. It might have been a penny-ante karate school when you were a child or the mean streets when you were older, but either way you know how to not get knocked down and to get back up again! The character gains a +2 dice pool modifier to all melee defense rolls and a +2 dice pool modifier to all rolls to resist melee damage. You may also stand up as a free action.
