You are well-versed in how to wield large weapons in a versatile fighting style, using the massive weight of your weapon to throw around your opponents, deflect blows or mitigate damage. You gain the following benefits:

• When you take the Dodge action on your turn while wielding a weapon with the heavy property, you enter a defensive stance. Until the beginning of your next turn, you gain a +1 bonus to your AC.
• When a creature targets you with a melee weapon attack while you are wielding a weapon with the heavy property, you can use your reaction to reduce the damage you would have taken by 1d10 + your proficiency bonus (to a minimum of 0 damage).
• You may channel your body weight fully into your swing, using the momentum to fuel a devastating attack. As an action, you can make a single attack with a melee weapon that has the heavy property against a Large or smaller sized creature within reach. On a hit, the target suffers the weapon attack’s normal effects and must succeed a Strength saving throw against a DC equal to (8 + your proficiency bonus + your Strength Modifier), on a failed save the creature is either knocked prone or pushed 10 ft away from you.
