A stream of acid emanates from you in a line 30ft long and 5ft wide in a direction you coose. Each creature in the line must succeed on a Dexterity saving throw or be covered in acid for the spell's duration or until a creature uses its action to scrape or wash the acid off itself or another creature. A creature covered in the acid takes 3d4 acid damage at the start of each of its turns.
When you cast this spell using a spell slot of 2nd level or higher,the damage increases by 1d4 for each slot level above 1st
