Invisible Stalker

Usage: cast invisible-stalker (victim)

This dark spell will pull a murderous spirit from its extraplanar home, and bind it to the caster's will. The evil spirit will track down the intended victim and use all powers at its command to slay them. Beware this spell does not give complete control of the creature to the caster. There is a chance the spirit will become angered and attack the one who summoned it.
