Choose one creature or nonmagical object that you can see within range. You transform the creature into a different creature, the creature into a nonmagical object, or the object into a creature. The transformation lasts for the duration, or until the target drops to 0 HP or dies. If you concentrate on this spell for the full duration, the transformation lasts until it is dispelled.
