Aqua Regia

You cause a gout of highly corrosive acid to spray out around you, corroding even the toughest of metals.

Each creature in a 15 ft. cone must make a Dexterity saving throw. On a failure, a target takes 5d12 acid damage, and if they are wearing non-magical armor, it is instantly destroyed. On a successful save, the target takes half as much damage, and the armor is not destroyed.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d12 per level of spell slot above 6th.
