Blacktorne's Melter

A glob of corrosive acid emanates from you landing on a space you choose. Each creature on the space must make a Dexterity saving throw. A creature takes 3d8 acid damage on a failed save, or half as much damage on a successful one.

On a failed saving throw the creature takes 1d8 per their turn until they spend 1 action to wipe away the acid.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the number of globs increases by each 1 for each slot level above 2nd, only one glob may occupy a space.
