I have tried a few spells, and got them wrong because I am a beginnner. One I tried was the "Inscoucient inclemency" spell to become a mermaid. On reflection, it was almost certainely far too advanced to try at the stage I was at. I got a few side affects, but otherwise it failed to work. I tried it again with a different necklace, but it didn't seem to do anything that time. I didn't get any side affects. I am worried that if I wish to try it again some time, it won't work because I have cast it too many times (badly)! Is this so?
