For any of my non-masochist friends who play on 0.2 difficulty and single player settings to avoid ARK’s terrible grinding, be aware that this boss is not weakened by difficulty, meaning that your lower level creatures will be fighting a true powered moeder that will hit for 2,000 damage regardless of difficulty. Your creatures will be stronger than normal due to singleplayer settings, but the boss will not take increased damage and its own damage will not be reduced. I lost an army of megalodons and tusos, all around level 100, believing this fight to be weaker than the dragon, but do not be fooled. The dragon does take the singleplayer nerfs quite a bit, making it a pathetic fight in comparison to moeder.

This also applies to the Dinopithecus King (wiped my rex and reaper army with about a third of its health left), but strangely not to the mini bosses on Fjordur, who will take the increased damage with decreased damage output. I have not tested this on any other boss, although I believe it also applies to the titans. Just wanted to leave this info here for any other 0.2 difficulty/singleplayer settings enjoyers that may exist, although it has been a while since I have met any.

TLDR: This boss and the Dinopithecus King is not nerfed by singleplayer settings, making them stronger than the dragon.
