Wave of Ooze

You conjure a wave of slime from the paraclemental plane of ooze to crash into your foes. The wave is 15 ft. wide and 10 ft. high and travels for 40 ft. in a straight line in a direction you choose emanating from you. Creatures caught in the wave's path must make a Dexterity saving throw or take 5d6 acid damage, or half that much on a successful saving throw. The wave doesn't travel through
obstacles but can pass over them. Creatures behind total cover take no damage. Creatures that failed their saving throws become coated in acidic o0ze that deals 1d6 acid damage at the start of each of their turns until scraped or washed away using an action. The area that the wave passed through becomes difficult terrain and becomes coated in ooze. Creatures passing through the area for the first time during each of their turns take 1d6 acid damage from the ooze. The ooze shrivels up and disappears after 1 minute.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the initial damage increases by 2d6
