Trying to understand the game

Hi everyone, trying to understand the new Dawn of the hunt league. When I'm still in the campaign act 3, I notice that my resistance was being decreased. Is there a reason why? Screenshot attached below when ungear all of the items.

Yes there is a reason - GGG hates us.

More seriously, an arbitrary penalty imposed on your resistances was used by GGG as part of the balancing process in POE1 and has been ported over into POE2. It is not very evident from the lore in the game why that resistance penalty should apply. You just have to deal with it. Sorry.

From the PoE 2 wiki:
"Characters receive a -10% penalty to elemental resistance at certain area level thresholds, approximately around the end of each act. By endgame, the cumulative penalty is -60% to all elemental resistances."

I believe the resistance penalty was initially larger in the 0.1 release of POE2 and then GGG dialled it back somewhat.

Ok I see, it's different from POE 1 although the finished campaign indeed is -60% to all elemental resistances. Thanks for the enlighten
