Flat dmg reduction is super good in pvm
the average thing in hell hits around 200dmg
I already made a char with so much flat pdr/mdr that absolutely nothing could deal 1 dmg to him in hell
those flat dmg reductions are calculated before res, so even when you face a unique with conviction aura, if you have enough to negate the dmg before the negative res, you dont take damage

Depending on where you farm, you could for exemple farm cows only -> they have 104-151 dmg
its possible to reach 151 pdr and be impossible for them to dmg you

in pvp its useless, unless you are an ES sorc
the flat dmg reduction is calculated on the remaining 5% dmg left, after the 6x pvp penalty
so an ES sorc with 50 pdr takes zero dmg from anything under 6k physical dmg as long as she has mana
even if she gets poisoned or open wounds down to 1 hp, she wont die with that 1 hp left if you cant deal more than 6k
The build called ''immortal sorc'' uses huge amount of flat dmg reduction from gladiator bane, Gerkes sanctuary, 25pdr amy and circ, etc.
she can actually take 0 dmg from ~30k dmg as long as she has mana left

Great lecture, big thanks

np man
Here's a fun exemple :
https://d2.maxroll.gg/d2planner/p301066w

Yes I know its a pretty bad troll build I just put together in a few mins for the laugh
but as you can see, I put this build vs hell cows in the calculations sheet, and it show zero dmg taken per hit

funny thing, they changed thorn/iron maider/SoB/IG to now return a flat amount of dmg instead of a %
so reducing to zero dmg taken still returns full dmg to the attacker haha
you can afk in cows and they slowly die on you
