With the 10 year anniversary just passed for
Throne of Bhaal, Sorcerer's Place has
updated their walkthrough offerings with new guides for Shadows of Amn and Throne of Bhaal:
Our older members will remember that we've had an excellent BG2 online walkthrough by Sylvus Moonbow available for over a decade, but sadly his guide was never completed and is missing a few areas. Montresor's comprehensive guide therefore supersedes it, but Sylvus' solution remains a treasure trove of valuable and interesting information (some of which is not covered by Montresor's), so I believe that they will nicely complement each other, along with Dave Milward's excellent downloadable walkthrough available on the same page.
