You've mastered the art of harnessing the heft of your weapon, using its mass to make your strikes even more potent. You gain the following benefits when using a weapon you are proficient with that has the two-handed or versatile property:

• When you roll a 1 or 2 on a damage die for an attack you make with a two-handed or versatile weapon, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2.
• 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.
• Your powerful build allows you to move an opponent. If you hit a creature with an opportunity attack when wielding a two-handed or versatile weapon, you can choose to push the target up to 10 feet away from you in a straight line.
• Increase the damage die size of your two-handed or versatile weapon by one step (for example, a d10 becomes a d12).

This feat emphasizes the powerful impact great weapons can have, offering more control over damage output and battlefield positioning.
