Spell of Cosmic Banishment
This spell is extremely powerful. It sends the victim hurtling through endless dimensions to the ultimate reaches of time and space, where all worlds of the cosmos are left behind, into a black void of everlasting nothingness. The character is alive, but essentially out of the game for a long time (until some god or other powerful being intervenes). Doctor Strange exiled Baron Mordo in this manner.
This spell should not be confused with the Spell of Vanishment.
