Power Glove

The Power Glove is a Hardmode accessory that doubles melee knockback and adds 12% increased melee speed. It simply combines the effects of Feral Claws and Titan Glove with no benefits lost.

Additionally, the Power Glove enables autoswing on all melee weapons and whips and increases the size of all melee weapons by 10%.
