excluding tea's and other potions i've made, because most of those are easily done and i don't think count as 'spells' i have cast 8 or 9 spells and they've all worked. i'm not big into casting, i'm more spiritual, i do make healing brews and do protection chants a lot, but in terms of cast a circle, charge, mix items together, chant and be all ceremonial, less than ten. it averages to about one a year i guess lol.
i give out so many spells, and have about 10 complete spell books [rather thick, about 300 pages each] and am almost done filling out another. i'm happier not casting, and i really have no need, but i would like to cast more, if i had any reason to that is lol.
