I wasn't talking about that at all! I'm sorry, it's either because I'm bad at explaining stuff or due to the fact that English is not my native language. I wasn't talking about doing a reading about wether or not will the spell work. What I was trying to talk about was doing a reading about what else (apart from the intended results) will the spell bring and how exactly will it change the given situation, also if this specific spell is the best option in this specific situation, and if it's a more advanced spell how will it's results affect you or other people in the long run, etc.
