Every cicrular room on the map has a Rare monster (except lightning caller vhalek's his is the muramite mob on east side of his doorway)
also from what I have seen Placate does not work on Any of the mobs which are located within these rooms. Some of the rooms also get very very dark if you go inside them if you're sky is turned off. Using simple or complex sky fixes this.
Also I've uploaded a new map to mapfiend for MPG :)
