Michael Morris said:K - just keep in mind that if you do allow the ability to even approach the power it has in the novel it's going to be a headache unless you and you're players are real good.
And I strongly recommend a thorough reading of those books before proceeding with any game based on the power that is the namesake of the first book.
Np. And from what you described, I doubt any DM would allow that kind of power in a game, unless we're talking about something truly epic going on. As described in the thread and via the now understood rules in the book, I don't think it would be that great a problem. It'd maybe be worth a single +1 ECL adjustment to balance things out or even the cost of a coupla feats.
