Maybe the organization could have been different in the Grimoire
It's a tad hard to get to all the, say, protection, spells as they're scattered about between the various categories as Fire magic, Earth magic, etc. That's OK if you're doing magic based on elements, but not everyone is. I'd have preferred that the spells be grouped more by the power used (Armor,
or Force Field, or Change Environment, etc) or by intent of the spell (protect character, damage others, find out information, etc)
The spells themselves are pretty good. If I had to make a suggestion here, it'd be to put in a section of "really neat" spells (either in effects or in method of construction) just to demonstrate the true versatility of the system.
