I ask this question because I have asked questions lately that play on the spellcasting mechanics of Anima: Beyond Fantasy lately, that nonetheless have almost nothing to do with a particular spell or spells in the space of possible answers, e.g. this one.
However, a question about getting a spellcasting attribute as high as possible clearly is about spellcasting, and I can't just not tag that, especially since there are particular points in the rules where "I'm using this attribute for spellcasting" matters - except it then is tagged spells!
Thus, I'd like to suggest we break the synonym between spellcasting and spells. It's not the same thing.
