Armour Damage Mitigation - Help

eserras7b16_ESO

Hi,

I would like to know how much damage does armour mitigate in a % form. For example 20.000 armour mitigates 35% of the damage recieved (this is just an example, don't know the numbers), same for spell resistance if possible. I've never been able to find such numbers so it's hard for me to calculate the amount of armour i need for my build.

Thank you in advance!

And for Zenimax: It would be cool to be provided with more information to calculate builds in the character screen, or in an oficial post in the webpage if you don't want to "dirty" the UI. Not only with the damage armour mitigates, also how many power does magicka/Stamina add, etc.

I cannot confirm if it works exactly as it did in 1.6 but below is how it use to work before the IC update.

it scales with level, up to a maximum cap of 50%
1 Armour is equivalent to 1 point of spell resist and 1 point of physical resist.
physical resistance calculation and spell resist calculation are the same and are as follows:

Resistance Value = RV
Character level = LVL

% = (RV-100) / (LVL*10)

eg. a level 49 character with 8,000 physical resistance
% = (8000-100)/(49*10) = 16.12% physical damage mitigation

please note after 49 you go to VR1 so this counts as 50, VR2 as 51 and so on (VR16 = 65)
please note after 49 you go to VR1 BUT this counts as 51, VR2 as 52 and so on (VR16 = 66) - thanks Asayre

Thank you so much !!

So, if the formula is still the same, the hardcap is now at 32600 at v16, isn't it ?

@willymchilybily is pretty much right. Copy and pasting from my other thread

Mitigation % = Spell resistance * (1-Penetration) / Target lvl*10) - Attacker focus / (Attacker lvl*10) - 0.12*Spell Erosion CP

you can replace spell resistance with physical resistance to get mitigation for physical attacks. Spell resistance and physical resistance can be read of your character sheet. Penetration refers to using the sharpened trait which is 14% for a legendary weapon. Attacker focus is 100 at base or 4984 for magicka uses with 5 light armour equipped and 2 points in the passive Concentration. The focus rating provided by Harven's Extended Stats does not always work with the formula I provided. Spell Erosion CP can be replaced with Piercing CP. Note that v16 is Lvl 66.

You may encounter some errors if doing damage calculations while wearing medium armour because of a bug with the passive Agility.

Mitigation % is hardcapped at 50% thus the harcap at V16 is 33000, ignoring focus and penetration.

Thanks @Asayre
I was never certain about this. I guess it must be right this way as it puts VR14 on the correct value

@RoyJade best use 33,100 to reach hard cap. According to VR1 actually being 51 not 50 as i previously stated.

Just curious if you had say, 45k armor, since you're above the hard cap, what would happen if someone had 10k of armor penetration, would you be left with the 50% mitigation still? Or would it count below the cap?

Asayre

You would still have 50% mitigation in your example, @zornyan

I was told that in 1.6 you could over stack armour (if you could actually manage it) and it would counteract some of the penetration. if we used Ayare's formula on what you ask (look at her post #5) it indicates this is true and actually not on a 1:1 basis (penetration works on %)

your example of 45,000 armor at VR16 [capped to 50%] would be used in the calculation of damage you take. The enemy penetration call it 25% would calculate on the total armor you have. 45,000 * (1-0.25). And still leaves 33,750 Resistance Value, and you stay at/above the cap.

but this is pure speculation from me if it still works, and works like this. Others know better than me true Min/maxing, app creating, PTS accessing, number crunchers. And the practicality of such stacking of Armour/resistance to break over the cap, dont know if the reward is worth it.

its not a hard cap but a softcap, hardcaped is only the 50% dmg reduction.

your armor value can be reduced by armor/spell piercing.
e.g. fighting something with 10k piercing it would be handsome to have 42,6k rating to still achieve 50% reduction. [all players and atleast in IC some mobs do have piercing values]

While % penetration is quite painful and pretty common as many players run with Sharpened or Nirnhoned weapons there are some other sources of flat penetration. I'll provide an example calculation for mitigation to give further insight into how the formula works.

Mitigation % = Spell resistance * (1-Penetration) / Target lvl*10) - Attacker focus / (Attacker lvl*10) - 0.12*Spell Erosion CP

Let's say the target has 35k spell resistance and is V16. The attacker is using a legendary sharpened weapon (14% penetration) and has a focus of 4984 (100 base + 4884 from Concentration passive). Please be wary of using the focus provided by Harven's extended stats. The number does not always work. For the focus value to work you should use a base of 100 and add anything that says increases spell penetration. The attacker also has 10 points in Spell Erosion and has casted Major Breach on the defender. The defender’s mitigation is then

Mitigation % = (35000 Spell resistance – 5280 Major Breach)*(1-0.14 Sharpened)/660 – 4984 Focus/660 – 0.12*10 Spell Erosion

Thus spell resistance over 33k is useful in counteracting the effects of penetration.
