Curse an Enemy Spell

"Gather the dirt from a footprint of your enemy. Put it in a bottle along with some Hot Foot Powder and bury it under your target's front porch or in their front yard. The only way this spell can be broken is by digging up the bottle and throwing it in a fire. If this is done and the bottle bursts, the spell is considered broken."
