Asura's Hands

Six spectral, floating arms appear on the user's back. The hand lasts for the duration or until you dismiss it as an action. The arms vanishes if it is ever more than 15 feet away from you or if you cast this spell again.

You can use your action to attack with a volley of punches or control a pair of arms. You can use one pair of arms to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can use your action to unleash a volley of punches, defender must roll 3d4 for damage. You can move the hand up to 30 feet each time you use it.

The hand can't activate magic items, or carry more than 10 pounds.
