This has happened to me once. I also attempted to write my own spell, only for luck, when I was starting my path. I did it with a few other friends. I wrote it incorrectly, I suppose I wasn't specific enough, I never said to bring good luck, and the next day we were all very sick.
Yeah, I really do need to make sure I cross all my T's and dot all my I's. I can't risk something like that again.
