Doryani's Prototype mechanic does not work on incoming damage from some spells

So, i see some posts about Lightning Mirage, and i don't understand, why it's still here.

So, i have 90% on lightning res and phys reduction (also fire and cold 88%).
And i can tank something like Volatile Flamebloods or Corpse Detonate or shaper's leap slam and so on.
I also get almost oneshoot from Mana Siphoning Ring Aura and shaper's beam - it's ok.

But why i take so huge damage(oneshot) from lightning hits from Lightning Mirage and Lightning Nova Spell?
Other lightning spells also make more damage than others elements. if I die, lightning damage is always to blame. And it's not lightning damage over time. From this I conclude that doriani is broken.

I think all knowes what is Lightning Mirage (clone).
A few words about Lightning Nova Spell:
it casted from Invulnerable Totems that cast Lightning Nova Spell.
And this totems was casted by Heralds of the Obelisk and Heralding Minions.
Also it casted by Sentinel traps (Unending Storm) in Lab.

A few words about this trap: In classic Eternal Labyrinth it deal around 7% of my es pool, but in Eternal Labyrinth of Fortune (Tribute to the Goddess) and in Eternal Labyrinth of Opportunity (Gift to the Goddess) it oneshooted me. Strange yeah?
I turned to the wiki and it says that traps do 30% more damage. Only the 30%!

I also noticed that these skills do not care if the molten shell is enabled. It still kills me in one shot.

My character have fortify, shock immunity, crit reduction 100%, 54% spell block, 675 es regen and full recovery es from block.

All the things listed above by me have been double-checked and cannot be pure coincidence.

I wonder why no one answers me?

The character screen is a bad estimate for physical damage reduction from armor. It is bad against large hits unless you are stacking ridiculous amounts like 100k plus. Those things are very large hits of lightning damage which means your armor is going to negate nowhere near the 75% damage reduction elemental damage is balanced around.

You either need to fully convert the lightning damage taken as something else or just never allow big lightning attacks to hit you

I wonder why it works like this? What difference does it make what size the hit is if the enemy does not have armor penetration?
In any case, if you looked at my screen, then I have almost 300k armor and your template answer does not fit

Hmm I did glance right over that. That is a lot of armor. I guess my brain read it as 28k the first time.

Only other thing I can see is a rather low es pool. But with that much armor it should negate a good chunk of the damage. Cant see for sure if its a one shot without checking lightning mirage damage and comparing that to how much reduction the armor would provide.

It seems to me that the damage of Lightning Mirage should not be greater than that of Volatile Flamebloods or Corpse Detonate.
Also Sentinel traps (Unending Storm) in Lab is Quite small.
All this is very strange and requires detailed verification.

Staff pls help with this
