Acid Rain

You create a cloud of acidic vapor roughly 15 feet above a space that you can see within range. Until the spell ends, the cloud rains down acid in a 5-foot cylinder. Any creature in the cylinder when you cast the spell must succeed on a Dexterity saving throw or take 1d8 acid damage. A creature must also make the saving throw when it moves into the cylinder for the first time on a turn or ends its turn there.

The acidic rain can melt through up to 1 inch of nonmagical stone if the spell lasts for its full duration.

The spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
