Unarmed Fighting

Your unarmed strikes do bludgeoning damage equal to 1d6 + your strength modifier. If you strike with two free hands the d6 becomes a d8. When you successfully start a grapple, you can deal 1d4 bludgeoning damage to the grappled creature. Until the grapple ends, you can also deal this damage to the creature whenever you hit it with a melee attack
