SoK, stop showing off!
(You beat her on GMGoW? Really?)
I gave up in the end - the fight was just too one-sided and I wasn’t even coming close. After weeks of optimization I was utterly unmanned.
Instead, I’ve gone with new game + to maximize armory and resistance (pre IOU’s my only found one Valkyrie damage reduction thingy and it made NO difference).
You know, I’m actually okay with admitting partial defeat - no way am I changing the difficulty! It would be a disservice to myself, the developers and the game (absolutely no aspersion-casting (SugarDave and Saladman, how can you live with yourselves?))...
