Blood Cauldron

You boil the blood in a creature you can see within range. The target must make a Constitution saving throw. On a failure the creature takes 4d10 acid damage, or half as much damage on a success. Afterwards, the target and all creatures within 10 feet of it must make a Dexterity saving throw. On a failure each creature takes 3d8 acid damage, or half as much damage on a success. If the target would take no damage on a successful save, they must take 1d6 acid damage.
