Lesser Weapon Master

You've learned to put the weight of a weapon to your advantage, letting its momentum empower your strikes. You gain the following benefits:

• On your turn, when you score a critical hit with a melee weapon you can make one melee weapon attack as a bonus action.
• Before you make a melee attack you are proficient with, you can choose to take a -3 penalty to the attack roll, you may do so once per round. If the attack hits, you add +2d6 to the attack's damage.
• Immediately after hitting a target, you may forgo all additional attacks, if you forgo at least 1 attack from the multi-attack action you may make one weapon strike as a bonus action. This attack is granted advantage.
