Serpentiginous Gloves

Wondrous item, uncommon (requires attunement)

These supple snakeskin gloves are decorated in fang-like patterns of multicolored jade scales.

You gain immunity to poison damage and the poisoned condition that would affect your hands, such as poisoned needle traps in the lock of a door or chest or touching a toxic creature. You are not otherwise protected from poison. The gloves can be worn individually or as a set. One glove allows you to make a bonus action that causes an adjacent creature to have vulnerability to poison damage until the end of their next turn. The other requires you to make an Attack action against a creature, and if that creature is damaged, as a bonus action you can then give them the poisoned condition. The creature can make a Constitution saving throw with a DC of 8 + your Constitution modifier + your proficiency bonus, at the end of each of its turns to try to end the poisoned condition. Once you use these abilities, you cannot use them any longer without first taking a long rest.

Epic Attunement. As an action, you can make a melee weapon attack against a creature. If you hit, you deal 1d12 poison damage. Additionally, unless the creature can make a Constitution saving throw with a DC of 8 + your Constitution modifier + your proficiency bonus, the creature is poisoned. The creature can make an additional saving throw at the end of each of its turns to end the poisoned effect.
