Oelm is right that the value of a treasure is unknown and the range varies greatly. For example, a level 7 treasure might be guarded by 10 dendroids, 80 royal griffins, or 100 orcs. It's impossible to guess.

There is a way to find out the truth. You need to create a template for a clone map, but make ALL the treasures NEUTRAL. Moreover, I also have a strong suspicion that Frozen Cliffs can only appear on snow. That is, for such a treasure to appear on a regular map, the treasure must be neutral and also have a snowy landscape.

SEM's words are, of course, complete nonsense, but there is still something sensible in them. It seems that Vicc said that the quality of objects in any zone depends on its size, i.e., there is a big difference if the zone is 10x10 cells or covers half the map. I may be wrong, of course.
