The Transformation spell is a spell that can be used to change someone into an animal temporarily.
Overview[edit | edit source]
In order to get the antivenom needed to create an antidote for gorgon venom, witch Rowena MacLeod used a transformation spell to transform the powerless Nephilim Jack Kline into a small dog. After being left alone by the vet, Jack was able to transform back, stole the antivenom and escaped.
Later, Rowena told Sam Winchester that when she cast the transformation spell, she felt another magic fighting hers. What she sensed of the other magic while casting the transformation spell left Rowena worried.
Procedure[edit | edit source]
The exact procedure is unknown, but the person under the spell appears to be able to control when they transform back to normal.
