Heavy Weapon Specialist

The weight of a heavy weapon no longer inhibits your movements, and you have learned to turn its momentum into power. You gain the following benefits:

• Being a Small creature doesn't impose disadvantage on weapon attacks with heavy weapons.
• On your turn, when you score a critical hit with a heavy weapon, you can make one weapon attack as a bonus action.
• When you make a melee attack roll with a heavy weapon, you can add your proficiency modifier to the attack's damage.
