Unarmed Fighting

You are an expert in unarmed fighting. Your fists, elbows, knees or otherwise are just as effective as most weapons, you gain the following benefits:

• Your unarmed strike uses a d6 for damage.
• When you make an unarmed strike with two free hands, the die increases by 1 step (d6 becomes a d8, etc).
• When you successfully grapple a creature, you can deal 1d4 bludgeoning damage to it. Until the grapple ends, you can also deal this damage to the creature whenever you hit it with a melee attack.
