Your unarmed strikes pack quite the punch. You gain the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• Your unarmed strikes can deal bludgeoning damage equal to 1d6 + your Strength modifier on a hit. If you aren’t wielding any weapons or a shield when you make the attack roll, the d6 becomes a d8.
• When you use the Attack action to make a melee attack on your turn, you can make one unarmed strike as a bonus action. The unarmed strike's damage die for this attack is a d4.
