I introduced the idea of a Grimore yesterday. The basic idea is, more spells without more templates, by creating “books of power” as noted in the Magic User template. Don’t need to get a talent to get the book (but that’s an option). Otherwise, if the DM allows it, can choose from these lists of spells.
Failing that, NPC magic users can use these spells to thrash the party. Also fun. Animating sand and rocks to beat up heroes will be MOST satisfying.
Here you are. Five new spells, and a book geared for a kind of research. It is not a template, but it greatly expands options for the magic users. Enjoy!
