Necorp

The arcane spell Necorp is not exactly an attack spell, but nonetheless very effective against the foes.

After preparing it, usage of this spell by the mage seriously weakens an entire group of foes, sapping the life out of them with a vampiric touch that while not killing, leaves them behind seriously weakened and thus easy to defeat in battle afterwards. It therefore is extremely useful for softening up the more powerful foes, before finishing them off with an attack spell like Noxum.
