You’ve learned to use the weight of a weapon to your advantage, letting its momentum empower your strikes. As a result, you gain the following benefits:

• Increase your Strength score by 1 to a maximum of 20.
• Immediately after you score a Critical Hit with a Melee Weapon or reduce a creature to 0 Hit Points with one, you can make one attack with the same weapon as a Bonus Action.
• When you hit a creature with a Heavy Weapon as part of the Attack Action on your turn, you can cause the weapon to deal extra damage to the target. The additional damage equals your Proficiency Bonus, and you can deal with it only once per turn.
• Heavy Weapon Expert: When you score a critical hit on a melee Attack roll (Two Handed Only), you can stun the target until the start of your next turn instead of doubling the damage.
