Klungar, you can specify a value for BatBrain to use for unknown monster stats with the unknown_ml ZLib setting. Not super helpful given that the numbers change every floor, but if you enter in numbers a bit tougher than where you are, it would work for a while. It still wouldn't work for the stat-adjustment attributes though.
Also ugh, bunches more new skills. I mean yay new challenge path.
EDIT: What's going on with Saucestorm? For me, BatBrain now guesses that it will deal 100 each hot/cold, when it's really dealing 50 each for 100 total. Should I upload a batfactors that halves that value?
