Reversing Spell

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 magick you performed, then think about how it went wrong. This should take no more than twenty 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."
