Advice Needed: Increase Survivability for Arcanist/Voidcaller

I was hoping to get some advice for increasing the survivability of my Arcanist/Voidcaller (Voidcaller is part of Cataclysm). I just started playing this game a few weeks ago, I currently am at level 57 and in the Plains of Strife area, playing on normal difficulty. In just a few short weeks this game has become one of my all time favorites and certainly one of, if not the best I have played in the last few years. I really hope that Grim Dawn continues having support from Crate Entertainment Devs to be able to provide us with more DLC and hopefully with a sequel at some point.

I have been finding situations where there are numerous mods hitting on me and I end up dead before I can even use a potion or something else to avoid death; other times, even when there are even more mobs, I have no issues whatsoever, not to mention any need to even think about using a potion. Recently the areas where deaths are more common for me have been zones labeled as the ‘challenge areas’ in the wiki along with Steps of Torment after using a skeleton key.

I was wondering if anyone could provide some advice for increasing my survivability? Which stats should I focus on increasing first? Are there any skills/items/abilities that I should be using? Any recommendations for Devotion Skills/Abilities that I should focus on acquiring?

Best thing you can do is get better resists and get more health after that. I’ve no idea wtf a voidcaller is, but if both of your classes lack some an in mastery heal then you should almost always grab some sort of heal like behemoth, dryad, etc in your devotions. Low resists of osme type sound like your problem if some enemies are a cakewalk and some are blowing you up
