Would anyone else like to see a collective book of all the feats from the Collective 3rd edition core & splat books? Along with the good ones from the Quintessential books, along with the other good 3rd party publishers?
Check out LI's newest book (for the moment anyway... busy schedule this year...) Spellbound . It's a fully detailed Ritual magic system that's compatible with and portable to D20 games. If your looking for a new magic system, this one is in addition to the current one, instead of replacing it. But it could certainly inspire someone to make Ritual casting a diffferent way of casting magic for one of the other core classes.
