Acidic Infection

Conjured, corrosive acid condenses, before shooting at an enemy within 60 feet. The target must make a Dexterity saving throw or take 3d8 acid damage, half on a successful save. Additionally, if the target fails the save they are covered in corrosive bile and take 3d8 acid damage at the start of each of their turns, this effect lasts while you maintain concentration or until the target uses an action to scrap off the acid from their body, at which point concentration on the spell fades. 

At Higher Levels. When you cast this spell using a spell slot of 5rd level or higher, the initial damage increases by 1d8 for each slot level above 4th.
