Plus this could of went under comments. Anyways yes people do say 99.9% of the spells will work, because we don't know if a couple of the spells will or not, but I wouldn't even try them, because 10 to 1 they wont.
ok, the fantasy section was created to file away fluffy spells instead of deleting them. as someone who practices dragon magick, and has a covenmate who works with fae, i do believe a couple spells in the fantasy section will work, but most won't. a spell to transform into these beings will not work, while a spell calling upon these beings for protection, luck, wealth [similar to calling upon the God and Goddess] will work.
if you want to cast a 'become a vampire', 'grow wings', 'grow a tail' or something along those lines, it won't work, magick doesn't work like that, these spells are 100% fake. if you were going to cast a spell calling upon astral beings energies, it might work.
