Pugilist

You're practiced at fighting rough-and-tumble with nothing but your fists. You gain the following benefits:

• Your unarmed strike uses a d4 for damage.
• When you take the Attack action with an unarmed strike, you can make one unarmed strike as a bonus action.
• While you aren’t wearing armor and not wielding a shield, your AC equals 13 + your Dexterity modifier.
