A willing creature you touch shape-shifts, along with everything it's wearing and carrying, into a misty cloud for the duration. The spell ends on the target if it drops to 0 Hit Points or if it takes a Magic action to end the spell on itself.
The target can't talk or manipulate objects, and any objects it was carrying or holding can't be dropped, used, or otherwise interacted with. Finally, the target can't attack or cast spells.
