Acid Stream

A stream of acid starts at the choosen point in range and emanates as a line 30 feet long, 15 feet heigth and 5 feet wide in a direction you choose. 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 3d6 acid damage at start of each of its turns. Creatures made by metal have disadvantage at saving throw.
