Here I am after a long time.
Unfortunately my Ranger died to Epic Undead Titans after an unforgivable mistake (equipped gear with less damage from titans and not for undead,and since my pierce res was low they ripped me....)
So for my 3d attempt i focused on survivability,made a Pilgrim (Hunting-Neidan) from scratch and finally did it.Completed all 3 difficulties until Ragnarok on Xmax+(5 bosses) no stash,self found gear,no deaths!
Currently i am playing Eternal Embers to completely fulfill the challenge.
This is the character
koolis - No_Death_Xmax+ - L82 Pilgrim AERAE (NO CURSES-UNTWINKED)
I made screenshots until end of act1 legendary when i encountered Toxeus at labyrinth so kept going recording on video.
Here is the whole progress from normal to legendary act1:
