Fecal Sodia

Summary
Fecal Sodia is a spell that manipulates the targets memories for the exclusive purpose of driving them insane. The memories altered cannot be controlled by the caster, but will automatically become whatever would drive the target the most insane. Its duration is determined by the caster, but will require more power to make it last longer. At the end of the duration, the normal memories are returned, but the time spent insane is also remembered.

Uses
Merlin commonly uses this spell to drive leaders of countries insane to bring down empires, or as a way of weakening his smarter enemies. The strongest known use of it was Merlin attempting to use it against Rex Malibu, but accidentally hitting Steven Waves. This caused Steven to become permanently insane.
