Brute's Stone Gauntlet

This large, rugged gauntlet is made from the hardened stone of the mountains. While wearing this gauntlet, your unarmed strikes deal an additional 1d4 bludgeoning damage. Additionally, once per long rest, you can use a bonus action to slam your fist against the ground, creating a tremor in a 10-foot radius. Each creature in that area must make a Dexterity saving throw (DC 13) or be knocked prone. On a successful save, they take half damage and are not knocked prone. You feel a rush of primal strength while wearing the gauntlet, enhancing your physical prowess.
