Instant death in Labyrinth Map (72) bossroom

I ''did'' a labirinth map with my lvl 83 duelist (nem) for the first time.
Shortly after entering i just died, couldnt see what happened so i'm Just curios what killed me...

The map was extra lighning dmg, and there where some blue Waterelementals (maybe extra dmg mod) standing around.

My stas are:
~5000 life
~40%evasion + Ondars guile
46% doge with frenzy charges
56% block
75%res (not overcapped)

As i said i went from full to 0 instantly, didnt even aggro the boss (i think)
My theory is they ele weaknessed me and just crit cold snapped me but the damage just seems to much.

Just wondering if any one else had a experience like that or knows whats going on ?

Yeah that boss + any damage mod = instant death for my 5.5k ES melee build. I can't even leech life fast enough to keep up with Vaal Pact... one volley of the attack kills me.

What builds can handle this boss with damage mods on the map? Just super tanky stuff with like 8k+ health or ES?

Arctic armour is godlike for this boss.

Arctic Armor, Immortal Call with Cast on dmg taken and some endurange charges/incr duration or CI/high chaos resist make the boss a LOT less scary.

The boss has a huge aoe omgwtf chaos projectile attack that will kill you harder than the jungle valley boss.

His damage is physical and chaos, so high armor/granites and chaos resist are your friends.

Thanks for the answers, didnt know he did chaos.
So i guess i just got unlike evading and -60 Chaos res and 0 armour certainly didnt help ...

It's half physical/half chaos EK, just like weaver and that minion of Dominus' use. You can not evade it. It's a spell.

He summons those things from the ground and they do a lot of damage when they come out of the ground ... it`s pointless to use any aoe skills there , because the boss will just devour the corpse and heal 100 % . My advice is to use single target skills and ignore the rest as much as possible.I`m a Damage over time build with viper strike , death`s oath , 2 x le heup of all , all the dot damage in the passive tree. I just 4 stack viper strike , vulnerability curse , puncture it and run and waitting for the boss to die.And yeah...7k here health 75+ chaos resist , and he still burst me down :)

whenever I see posts like this it makes me wonder how some of you who get completely raped in these maps without even having a chance to react aren't completely pissed off with this stupid game.

I mean sure, there are probably ways to mitigate such damage and survive such a map, but its like you need to know how to arm yourself prior to this map, and then change all your stats for another boss in another map that does a different "one shot" mechanic or some one off mod.

I just can't understand why some of you sound so passive after losing a high level nemesis character that you've carefully played and crafted for days/weeks/month only to have it stripped from you and thrown into HC just by running into a map and getting squashed..

I will never play HC in this game because of all these stories I've read on here.. its such a waste of fucking time in the end of it all
