The context is some overthinking I am doing.
So, the magic available in the Big Gold Book doesn't have the utilitarian magic I have in mind for the setting at the other end of the link. I've ordered the magic book, which to my surprise an Amazon supplier had. I have Chaosium library, so I can also pick and choose from RQ2, Magic World, and Elf Quest (the plant and animal-shaping magic in particular). Any obvious games I should be nicking spells from.
