I need help to figure out how Physical Damage reduction works

Hi everyone,

I am currently trying to figure out where to go next with my Artillery Ballista Champ (Ziz Build basically). PoB: https://pobb.in/KTG6JZ6D3HeL

I was clicking around in PoB and noticed that my "Physical Max Hit" is a lot lower than my Elemental Max hit: ~9.7k vs 28.6k. Ele max hit is 2,94 times higher than phys max hit.
I have 75% max res and 69% physical damage reduction.From a 100 damage hit, I should take 25 ele damage or 31 physical damage. That is a factor of 1,24.

If I go into the Calcs tab in PoB and go to "maximum hit taken", physical damage is calculated with a 0.611 factor, which indicates (to me) that i take roughly 61% of the damage from a physical hit, when it "should" be 31%.

What am I missing?

Ele res directly reduces damage by 75%, 69% - estimated damage reduction against white monster's default hit.

So basically: armour is less effective against stronger enemies?

No, you just need to match your armor to the content you are running. You won't be using a white sword you found on twighlight strand in red maps right? With armor it's the same.
But the white sword will always do the the same damage, no matter what mob I hit. It's not going to kill endgame content, but it still does 5-10 damage, just as it did when I fought Hillok with it.
This does not seem to be the case with armour, as far as I understand now.

Yes, armour is less effective against stronger hits

Real % phys damage reduction


(This does not count pure "% phys damage reduction" from item mods or endurance charges.)
