UPDATED: September 2 - more map data
Went through a few runs of the Arkandian Revenant Mystery Dungeon during the past few days, where even non-rare resources are hard to find, and did a map dump of the dungeon. (And there might be at least one map missing here). Link for larger version of this image
Conclusion: There are a few ingredients, the most important being Holy Water, that is not obtainable in any room of this repeatable dungeon.*
NOTE: You may have noticed there's a large gap between this image and the last one in the Fall 2011 image set - I will put them up as I finish them.
