Acid Orb

You hurl a bubble of acid. Choose one or two creatures you can see within range. If you choose two, they must be within 5 feet of each other. A target must succeed on a Dexterity saving throw or take 1d8 + your spellcasting ability modifier acid damage. Regardless of the saving throw the blob explodes and splatters its surroundings with acid. The target or targets take 1d4 acid damage at the start of their next turn, unless they spend an action to wipe off the acid.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
