I got another issue, when editing hardcoreNPC armor and vit values, it just is all over the place, right now I have a modifier of 500% for the armors and 100 vitality, the first NPC(the magister) has 48 armor, 24 magic armor and 60 vit, which just doesn't fit, if I use things like 75% armor I don't see any change at all compared to vanilla
What is your "Act Part" field set to? That affects how the other stats scale. An Act Part of 12 seems to be a 1:1 for the numbers you put in, i.e. 50 fire resistance is 50%.
