The Devil's Coin (5e Equipment)

Wondrous item, very rare

This enigmatic coin harbors a horned devil within. You can engage in conversation with it for advice, although beware, as it might be attempting to deceive you. While holding this coin, you can use an action to cast the pass without trace spell with it. The coin cannot be used this way again until the next dawn.
Additionally, while holding this coin, you can speak its command word as an action to summon the horned devil within it. The devil appears in an unoccupied space you choose within 30 feet of you. It remains for 1 hour or until it drops to 0 hit points. It then returns to the Nine Hells and the coin shatters.
While summoned, the devil is friendly to you and your companions. It obeys any commands you give it, no matter what language you use. If you fail to command it, the devil defends itself against attackers but takes no other actions.
