This is an UNBELIEVABLY simple spell that will reverse your last spell. For example, if you made it rain, it will make it stop raining. It also removes your last spell, like if you put a lust spell on somebody and want to get rid of it. All right, enough blabbing, here it is:
First off, think about the last spell you cast, because this only works for your most recent spell, hex, curse, whatever you did.
Just think about the actual magic you performed, then think about how it went wrong. This should take no more than 20 seconds AT THE MOST. Now say this in a clear voice in these EXACT words without stuttering, mumbling, getting your tongue twisted, etc.:
"My spell went wrong,
Please reverse it,
Don't mess it up,
And don't pervert it."
If you performed the reversing process correctly, it should work.
