Honestly, Map Completion criteria feels random

I think we just need a better completion concept, cuz this feels like a prototype.

Random negative consequences off the top of my head:
#1: Ranged characters can offscreen the remaining rares once they're visible on
the map.
#2: Rare monsters in obscure locations, leading to excessive backtracking/boredom.
#3: Knowing that there are no remaining Rare monsters is overall just demotivating
in terms of clearing a map.
#4: Minimap icons breaks immersion. Less than 200 monsters is algorithmic and
arbitrary.
#5: Increasing number of Rare monsters slows down completion.
