Yes, the math itself seams to be a mess too. I tested diffirent versions of the same guns and results was consistent, but i wouldn’t be surprised if i missed something.
By the way. Is Brittleness and rending suppose to affect non carapace and flak? Because they do.
not sure, haven’t looked into armor mechanic too much, but if V2 is anything to go by, my assumtion is that the enemy tags like unyielding even unarmored are their “armor type”
so “unarmored” are not without resistances
in V2 packrats weren’t armored but had high resistances because they had the same “armor type” as monsters
so maybe both rending and bittle don’t reduce armor, but damage resistance of their “armor type”
Yes, it is supposed to affects all armor types. If you do <100% base damage, every 1% will add 1% to the armor modifier until you hit 100%. After that, every 4% will add 1%
