A more powerful show of the potential of acidic magic spells then the spell
disruption, is the spell acid wind. While not using any actual acid, it causes
a sharp breeze  to swirl around the target. While the breeze isn't actually
acid, it is very acidic in nature. It can damage the target and also do damage
to his equipment. It is said that this is  one of the slowest and most painful
ways to kill a foe that cannot escape.
