Oversized Weapon Mastery

You’ve gotten used to the weight of your heavy weaponry. You gain the following benefits:

• Smallfolk can now wield weapons with Heavy property normally.
• On your turn, when you score a critical hit with an attack using heavy melee weapon or reduce a creature to 0 hit points with one, the momentum of your strike will make you choose another creature within range to be hit by the same weapon with separate attack roll.
• Before you make a melee weapon attack with a heavy weapon that you are proficient with, you can choose to retain the disadvantage on the attack roll. If the attack hits, you add +5 to the attack’s damage.
