Help with the Warden on Elite

Hey Guys. I am currently playing a Nightblade+Arcanist and I am having heavy problems with the Warden on Elite. As soons as he charges me (what usually happens after a few seconds), he instagibs me.
I don’t know if I am SUPER unlucky with my drops, my resistance is just shot or what else. Can you help me?

No Idea what I screwed up besides low HP (No Idea actually) or too low resistances.

Your HP is WAYY TOO LOW for Elite. I would get at least 4k of HP going into Elite.

I would grab some devotion-based health nodes - lion, chaos crossroad point, order crossroad point, Behemoth, Scales of Ulcama, Dryad etc.

Your aether resistance should also be higher, around 40% or so in Elite - use aura from purified salt.

The funny thing is: the Aura is on in that pic. Without it I would have only 12% Resitance. Also the Chaos-Crossroads Point is already active. Anything else besides the Lion? (My guess would be only the first two points into the Lion?)

With 2,5k hp its a wonder you haven’t been oneshot on your way to him. Put more points in mastery bars, get rid of all these skills you do not really need, yet. I do not know which ones, but I will try to guess http://grimcalc.com/build/Kz9d0H

I had 10,5k HP at level 50 on my battlemage…how did you manage to get through the game is beyond me.

Coming trough the game was pretty easy. Only real problem I had was the Loghorrean, which I had to zerg a bit.

you haven’t been oneshot on your way to him.

Well, Flash Freeze helps a lot with that. Maxed out it nearly oneshots most Mobs that aren’t Frost-Resitant.

/E: I got him. Thanks mammothhunter, I used parts of your suggestions. Still wasn’t easy but he was far from one-shotting me.
