So when I run pits (100+) and torment boss (zir and duriel) with my bonespirit necro I’m able to hit 1 Billion + damage. However I noticed recently when I do regular duriel runs my bone spirit will never hit more than ~300ish million. I’m using the same gear and doing the same thing (stack multipliers via curse, corpses, vulnerable proc etc etc).

Is this because there’s some kind of damage scaling going on where your damage numbers are scales up in pits or specifically against monsters with higher level than your character (lv100).
