Slugger

You learned the art of crushing your enemies and putting your weight into your strikes, granting you the following benefits:

• Before you make a melee attack with an unarmed strike, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
• Once per turn, when you hit a creature with an attack that deals bludgeoning damage, you can move it 5 feet to an unoccupied space, provided the target is no more than one size larger than you.
• When you score a critical hit that deals bludgeoning damage to a creature, attack rolls against that creature are made with advantage until the start of your next turn.
