Spell: Disintegrating Puddle

You spit out a green glob of dangerous acid that increases in size as it flies at the target, splashing around them as it hits them. Make a ranged spell attack against the target. On a success, the target takes 2d12 acid damage, and acid splatters to the ground in the target's space and all spaces adjacent to the target. On a critical hit, the target takes double damage. The acid puddle lasts for 1 minute; a creature that enters or starts its turn in the acid puddle takes 0d4 acid damage.

Heightened (+2) The initial acid damage increases by 2d12, and the acid puddle damage increases by 1d4.
