The Elder Scrolls: Tamriel

You summon a ghostly apparition to assist you. The ghost appears in an unoccupied space within 30 feet and follows your verbal commands. The ghost remains for 1 hour, until it is destroyed, or until you dismiss it as a bonus action. The ghost has the stats of a basic ghost and is ethereal, allowing it to move through solid objects. It can perform basic attacks and is resistant to non-magical damage.
