How about some more acid for your games!
Casting Time: 1 action
Range: 150 feet
Components: V, S, M (a bit of bull bile)
A concentrated burst of acid flares to life covering everything in a 20-foor radius of a point in range. Each creature in the area must make a Dexterity saving throw. A target takes 10d4 acid damage on a failed save, or half as much damage on a successful one. In addition, the acid eats through armor of creatures in range. Creatures not wearing magic armor that filed their save have their AC reduced by 2 until the damage is repaired. Those that saved only have their AC reduced by 1. Creatures wearing magic armor that fail the save have their AC reduced by 1, while those that save do not have their AC reduced at all.
The acid also causes damage to all objects in the area of effect, possibly destroying them.
At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d4 for each slot level above 3rd.
