Boot Leg Mage Hand

A spectral, floating hand appears at a point you choose within range... Or at least, that's what it would do if it worked. Instead, it causes your physical hand to pop off of your wrist, dealing a 1d4 of damage to yourself and allowing the hand to float freely. The hand lasts for the duration or until you dismiss it as an action. The hand cannot move more than 30 feet away from you.

You can use your action to control the hand. You can use the hand 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 move the hand up to 30 feet each time you use it.

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