Oathkeeper's Gauntlets

When you use Divine Smite, you may reroll one damage die and must take the new roll. Additionally, once per long rest, you may cast Compelled Duel (DC 14) without expending a spell slot.

“Forged in the forges of an ancient order, these gauntlets bear the weight of every sacred vow sworn by their wielder. They tighten in the presence of dishonor, demanding justice.”
