What is a reverse spell..

It can not work no matter the amount of energy. Unfortunately a bunch of the spells on here are fake. Your mind is making you feel the side effects.

You are thinking too much about it..these spells DO NOT work. they are FAKE....try concentrating at other things of life and you will eventually forget about it. No one can grow a tail using a spell unless he makes one out of a twig and sticks it in his back. So yeah, you have nothing to worry about :)

whay is the spell to get a tail please tell
