Cauldron of Health

On your turn, you use one action to summon the Cauldron of Health, which floats above the caster's head. On your next turn, you can use an action to use the Cauldron to heal one living thing to full health. For each additional spell slot level this spell is cast at, one additional living thing can be restored to full health. Example: a second level spell slot can heal two living things, a third level spell slot can heal three living things, and so forth.
