Is Magic Resistance OP?

Magic Resistance as flat reduction or percentage Resistance counts for magic attacks like for example the Viper Bone Spear as well as for all dealt elemental damage (cold, fire, lightning). Would that be correct?

So if I for example use the Horazon boots with 30% mr and a Dwarf Star with 15% fire absorb and 15 mdr and have Fire Res capped at 75% and get hit for 1000 fire damage would that mean:

Fire Resistance reduces damage to 250, then Magic Resistance reduces those 250 by another 75 to make it 175.
Now 15% Fire Absorb from Dwarf Star reduce those 175 to 149.
Mdr from Dwarf Star subtracts another 15 to make it 134 and now the Fire Absorb heals back 26 to finally let me take 108 damage from that hit.

Is this correct or am I misunderstanding this?

I am probably not correct because that would make magic Resistance completely overpowered, right? I mean it essentially always probably, but we didnt have sources.

You are completely correct and not misunderstanding. You did good.

So, magic resistance is really an additional source of Quad Res (+ Magic, monus Poison) in one affix? Dang.

Let me clarify this: Are the Horazon Boots Quad Res Boots with 30% frw, Str, Dex and CBF?

Most gg boots since hot spurs

Seems like I wasnt correct. While MDR, like for example on Vamp Gaze, Dwarf Star or Gerke's, really reduces ALL damage from magical AND elemental attacks (fire, cold, lightning) and on top of that also physical damage - if theres any excess reduction after the initial main elemant was fully negated to zero - Magic Resistance doesnt do that.

Its what you'd think it is. It reduces magical attacks only. Like Bone Spells f.e.

Thought they'd be, but I just posted where I was wrong. Maybe someone with more knowledge on the topic could clarify or deny?

Magic is 5th element, mdr work great with energy shield (e.g viper socketed mal

It is a fifth (or sixth if you count physical), yes. But mdr applies to all elements - or can at least

*add a 9th row for warlocks as Blood Oath is reducing the dmg taken by 3 + [2 x hard points]%

Also this wasn’t updated for RotW, it’s missing info for -% EMR and -% EDR
