Hi all, I was wondering if any of the GMs who ran/read (or is currently running/reading) Spires of Xin-Shalast has developed this book in any way. My players have just defeated Ghlorofaex and are now heading to the Shahlaria to butcher a few rune giants (in order to free other giants from their mind control and receive some help in liberating the city from the minions of Karzoug). If they manage to clean the fortress from the rune giants' presence, I think it would be fair to reward them with the Ebidwar, and here I am asking for some suggestions.
At the moment I have only decided that it is going to be a minor artifact that bestows some powers and benefits on those who read it. In order not to abuse it, only one reader can benefit from it at a time (just like the books that raise ability scores can be read by only one person). In order for anyone else to benefit from the book, the previuos reader must be either dead or willing to renounce the powers bestowed by the Ebidwar.
Some abilities that sprang to mind are bonuses to Leadership score, AC, saving throws, weapon attacks and damage, Knowledge checks regarding the identification of monsters' offensive and defensive abilities, permanent bonuses to Intelligence/Wisdom/Charisma, ranks in Knowledge (nobility) and (engineering), and maybe some spells and feats to be used while holding the book.
What I'm looking for are suggestions on how to further develop those ideas, quantify bonuses, select granted spells and feats, and of course setting the price to be paid for such powers. After all, as a minor artifact, I expect the Edibwar to have an Ego score :)
Let the suggestions flow!
