As with most the spells on this site, some 'trick' spells are real and some aren't. You just have to use your judgement. If it says "just snap your fingers, say alakazam and a huge fireball will appear", then that would be just some roleplayer slime trying to mess with people. Usually the more detail they go into, the more sincere the spell is, but don't go by that alone. Just trust your judgment!
some of the spells are unbelievable. i know some spells that would literally blow u away. not only are they complicated, but they can teach u to summon and control tornados, infernos, tsunamis, and much, much more
