This spell creates a phantasmal image of the most fearsome
creature matching to targets fears. If the target fails to
recognize the image as unreal, the killer will attack the
target. Sometimes the worst has happened and the target has
simply died of fear when he had seen this horrible image in
his head. The unleashed creature can sometimes even attack
the caster but this is quite rare.
If you are in a party, you need to be in the first row because
this spell requires that you touch the victims head and find out
what is the most fearsome thing that the target
fears.
