Martial Arts (tGz)

You gain the following benefits while you are unarmed or wielding only and you aren’t wearing armor or wielding a shield:

• You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes, shortswords and any simple melee weapons that don’t have the two-handed or heavy property. 
• You can roll a d4 in place of the normal damage of your unarmed strike or monk weapon. This die changes as you gain levels, it becomes a d6 at 5th level, d8 at 11th level, d10 at 17th level. 
• When you use the Attack action with an unarmed strike on your turn, you can make one unarmed strike as a bonus action.
