The survival elements are fine, I just wish the resistance buffs would last a bit longer. I went through almost a page of prepared frost resistance food while scaling the mountain. And ofcourse you only find heat resistance ingredients up there and without a cooking pot you can't make anymore anyway. So eventually I had to jump off the mountain not to die when I ran out. 6 minute buffs are nothing, some fights can last half an hour...
Btw is it possible to carry a cooking pot around? Or will carrying a torch keep me warm on the move. (I didn't have room in the inventory to also take torches, yet can carry 2 tons of food!)
