* ''Defigere Et Depurgare,''or as it is known in its English translation "To bind and purge," - A spell created by Rowena in the 18th century that causes demons to liquefy and get coughed up out of their meatsuit. It appears that the spell binds the demon to its meatsuit to keep it from escaping as it begins to liquefy the smoke into a sludge-like substance and be purged from the host body. The spell was only practiced by Rowena and before she used it to kill Raul, hadn't been seen since the 18th century. Sam attempted to use a strengthened version of the spell to kill Crowley and satisfy his deal with Rowena, but while the spell manages to temporarily incapacitate him, Crowley eventually overcomes the spell's effects and sets the hex bag on fire.
* ''Impetus bestiarum'' (attacks of beasts), or as Rowena referred to it, "attack dog spell", is a spell wherein the witch places a hex bag in the hands of someone and recites "impetus bestiarum," turning the object of the spell into an animalistic killer who can be directed to kill a particular individual. The spell will eventually kill the person it is cast on unless the spell is reversed by the witch who inflicted it by reciting "desiste ad levo onus tuum."
* Resurrection Spell - A spell devised by Rowena and completed by Sam Winchester which causes a spirit to become human. Unfortunately, the spell could only be used once as Billie closes any loophole that cheats death.
