I'm running this adventure for my group of experienced players and the treasury maze gave them no end of problems and two (the fighters) deaths in the vortex of lava. The maps are lovely but I wish the stairs and chutes etc. had the rooms to where they lead marked on them. e.g up to area D12. This would have saved lots of time flicking from one map to the next and having to read the text to see how the rooms on different levels are connected.
