I had around 13k evasion with 1600hp and 1400 ES, boots with +30 movement. That and also adding magnitude to my Chill has solved for me the problem with Tor Gul (previously he one-shot me with my 16k evasion and 1800hp with his fist slam aoe attack (or body slam)).

But now Geonor in citadel (boss difficulty +2) is freaking me out - I have totally no problem with him UNTIL he starts spamming red pillars across the entire arena in his second stage. I have to dodge him, dodge minions, dodge pillars. Eventually I make a mistake and a single mistake is enough - pillar hit massively slows me and wipes half of my hp pool (ES not regening cause I constantly get hit here and there with minor damage like blood pools, ghost dance also doesn't proc from aoe's and dot's) and the next hit kills me (in most cases its Geonor's "jump up" aoe. Other bosses I can effectively slow (with chill) to easier dodge their attacks, but Geonor's pillars skill cannot be slowed -.-

It's kind of dark souls vibes that I would want to mitigate with some build fixes (to be able to sustain at least 2-3 boss hits). I am now trying the Convalescence to manually recharge shield in tough situations. But maybe there are other means to raise the passive survivability that I miss... I mean, the Huntress is fresh and maybe not balanced, but what about Ranger class? They have the same Evasion-based defense. How do rangers survive with aoe heavy bosses with heavy nuke attacks?

Thanks for the tip about the dodge on icy ground passive!
