One of the most deadly spells known, is the feared spell, killing cloud. When this spell is cast, a heavy mist appears, that envelopes the target area. Any foes caught in the mist are instantly overcome by a mixture of hundreds of deadly poisons. Some victims fall dead instantly as the poisons overload the nervous system. Others simply melt away as poisons eat away at flesh and bone at a mind boggling rate. Those that survive a killing cloud, are instantly on the throes of hell.
