Mage Hand is a conjuration cantrip available to bards, sorcerers, warlocks, and wizards.
You use your action to create a spectral, floating hand at a point you choose. Once made, you can use your action to control the hand. It can move up to 30 feet at a time, but can't be more than 30 feet away from you or it will vanish. The hand is able to manipulate objects, open an unlocked door or container, put away or get an item out of an open container, or pour out a vial's contents. It can't attack, activate magic items, or carry more than 10 pounds. You use an action to dismiss the hand before the end of the duration.
