Boxer

Prerequisite: Str 12 and Dex 12

When both of your hands are free and an enemy attacks you in melee, you can attempt to deflect that blow as a reaction. The triggering attack roll is made with disadvantage when you decide to use this reaction. If the triggering attack misses, your next attack roll against that enemy is made with advantage so long as that attack is made before the end of your next turn. This reaction cannot be used on successive turns.
