I all you could use were the 3 core rulebooks and just this ONE book what would that one be?
Pick a specific book that exists, rather than saying a type of book.
Narrow it down and just pick one. Note: it doesn't even have to be a RPG book.
And tell us why you feel that way.
For me it is Monte Cook's Arcana Evolved Spell Treasury. I like it because the spells in there are so unique, in that they bring more to the game than just different ways to damage or tinker with stats and scores. Just by reading them I think of how my casters can be more creative, envisioning scenarios in which I can do the unexpected.
