Ring of Petty Affliction

Ring, common (requires attunement)

This plain silver ring is set with a small, round onyx. While wearing it, you can use your action to cause a creature you can see within 60 feet of you to experience a painful and distracting cramp. The target must succeed on a DC 13 Constitution saving throw or have disadvantage on the next weapon attack roll it makes before the end of its next turn.
