Acid Orb

You create a fist-sized, green ball of acid and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 5d4 acid damage. Hit or miss, the ball then explodes. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d4 acid damage.

A creature that fails its saving throw is also melting for 1d4 rounds. A melting creature takes 2d4 acid damage at the start of each of its turns.

At Higher Levels. When you cast this spell using a spell slot of 3rd-level or higher, the target damage and the acid damage of the explosion increases by 1d4 for each slot level above 2nd.
