Cup's Great 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:

• Increase your Strength score by 1
• On your turn, when you score a critical hit with a melee weapon or reduce a creature to 0 hit points with one, you can make one melee weapon attack as a bonus action.
• When you hit a creature with a melee attack with a heavy weapon that you are proficient with, you can choose to add +10 to the attack's damage. You can do this a number of times equal to your proficiency bonus, and you regain all spent uses when you finish a Long Rest
