Were-Wolf Spells

Are there any werewolf spells that actually work? If not, is there one where I can get a wolf tail?

And by werewolf spells, I mean transform into one, not summon one.

No, that is just pure fantasy, not going to happen

No there is no such thing as a werewolf and no spell will allow you to alter your DNA to become a mythological creature.

There is something called the werewolf path but this is a religion if I'm correct

As has already been stated, those spells are all fake. You are human, and human you shall always be.
