Curse of the Suffering Toad

Take the hair of your victim and tie it to the leg of a toad, put the toad into the covered pot. As the toad suffers, the victim will too, suffering from the same pain inflicted to the toad. The toad will die after an hour, if it dies in the pot then the target of the spell takes 3d6 Necrotic damage. Casting this at a higher level increase the damage by a d6 per spell level above level 3. If the target leaves the range of the toad in the pot, then they are unaffected. If a creature survives this curse, they are immune to it for the next 24 hours.
