I have made my first attempt to play through the book, which ended at the Lavas on the Plane of Darkness, but since I don't have time to have another go now, here's what I found this far:
(ne) 17tdoi imprvdsc: Shouldn't Mindfort be encoded as a spell (even though it strictly might not be)? (??) 17tdoi 57: Xaagon the Deathlord's city -> Xaagon, the Deathlord's city (??) 17tdoi 64: There is a continuity problem here - you may have arrived by another path than through the curtain of light. (ft) 17tdoi 125: According to Section 6, the Kajarda *are* undead. (ft) 17tdoi 169: We don't footnote what to do if you have no items in those positions in these cases, do we? (??) 17tdoi 220: Should "Weapon" be capitalized in this section? If not, it should be decapitalized in a bunch of other places in the books... (??) 17tdoi 220: Can "Weapons List" be made into a link into the Action Chart? And BTW, the heading there is just "Weapons", not "Weapons List". (ne) 17tdoi 223: See Mindfort comment on Improved Disciplines. (??) 17tdoi map: Ixia the Hardlands -> Ixia and the Hardlands [tw: sounds like a more likely map title]
