Acid Bomb

A bubble-like concentration of pure acid will begin to form at the tip of the wand, which you can aim while it is charging, and hurl at a target area. The target must then make a Dexterity save with a DC of 17. On a hit, the target takes 1d10 damage, and the area (4 feet circle) becomes difficult terrain for 3 turns, then disappears. All objects that can be melted by acid in the area will begin to melt after the acid makes contact, and will effectively be melted after 3 turns. The target must also take an action to remove the acid, else be dealt 2 points of Acid DOT for 3 turns.

Spell Level Upgrade. The damage increases by 1d10 when you reach levels 5 (2d10), 11 (3d10), and 17 (4d10).
