Corrosive slime envelops your hand to melt the skin of a creature you try to touch. Make a melee spell attack against the target. On a hit, the target takes 2d12 acid damage. If the target is wearing armor, you can forgo the damage to do a permanent -1 to the AC the armor grants.

At Higher Levels. When you cast a spell using a spell slot of 2nd level or higher, the damage increases by 1d12 for each slot level above 1st.
