I am just over lvl 80 now with my EQ jugg. Life just went over 5k, all res capped but chaos res is still negative. Will buy a better amulet with chaos res to fix this. Armour I can't remember but it is more than 40% mitigation. I have 9 endurance charges, and with Kaoms Way ring that is 3,6% regen I think. Also have life leech of about 3%. Problem is some bosses still whack me, but I think that is because of chaos res. It was a map with 3 skeleton bosses, including the one with the poison arrows. He 1 shot me a few times. Only up to lvl 8 maps, and it is starting to get a bit harder. But if I have my charges up it is not too bad. Still have a few levels to go. Anything else I can do to get tougher?
Unfortunately for the EQ Jugg, it is all about Max HP and Armour. Also your flasks being optimised will help, if they are not already. And actually using your flasks properly will also help a lot.
I find that the only time I get stomped with my tanky characters, is when I YOLO it and forget to preflask before the first hit.
Making sure you have fortify on is also an important factor.
Here is a list of mechanics that you can leverage to boost your tankiness, under certain conditions of course.
1) Optimise flasks and use them correctly.
2) Utilise the blind mechanic (As long as you dont have unwavering stance activated on the tree) Blind is incredible. So a stibnite flask is a good option.
3) Modify your gear to include armour and evasion rating. This goes hand in hand with the blind mechanic.
4) Bring enfeeble into your build, instead of warlords. The requirement here is to find enough mana leech to sustain your EQ spam on a single target. Not sure what that is exactly. If you can get a 0.4% mana leech on your gloves, that would probably sustain you. I guess you have other lifesteal besides warlords, so that shouldn't be too bad. Your HP regen and actually using your life flask, should compensate enough in most cases. To ensure that you can get Endurance charges up on demand, put enduring cry on a weapon swap. Sometimes it is a bit dangerous to go into a boss fight and hope that his first hit is gentle and procs your 20% chance to get an endurance charge on being hit.
If you can stack 2,3 and 4 together successfully, They layer and amplify one another much more than you might think. Have a look at the wiki to get an indepth understanding of it, and watch Ziggy D's video on Enfeeble and evasion stacking. But basically, enfeeble reducing a monster's accuracy, will directly increase your chance to evade, because of how the formula works.
Blind is then layered ontop of, so an additive effect instead of a multiplicative one. Because blind's formula uses your final chance to evade as one of the formula parameters.
You can go from a 15% chance to evade, and boost that to like 22% with enfeeble. Then adding blind would increase that to about 39% or so.
You can see how all of those together can really stack up. If you absolutely cannot find a way to weave enfeeble into your setup. Then at least get as much evasion as possible, and use a stibnite flask to multiply that evasion and blind nearby enemies with a smoke cloud.
Finally, if you don't already. Make sure to have one of every elemental resist flask, well rolled and at the ready for boss fights that do heavy elemental damage. Elemental damage is the biggest danger to you, so knowing your enemy and boosting your max resist by 6% with the correct flask at the right time, is your strongest tool to deal with that.
