Biggest Threat To Juggernaut?

Filthy casual here...

I lately exclusively play SSFHC cause since I don't get to play much, and I want to make my playtime count...

Anyway, I'm playing a juggernaut for the first time. Yeah, the one with all the endurance charges and life leech, etc.

So i've breezed through to act 5, and the only halfway of a close call was against innocence or sin (whichever one).

So from act 5 on, what should I look out for? What areas/bosses are a threat? Anything?

Right now, I am capped on resists and have about 2000 hp. Level 45. Fixing to run the second lab...

Any comments are appreciated. Thanks!

The crab boss in act 6 isn't one that you can tank... unless you've twinked your character to the gills. He'll knock you out, and make sure you have your fire resistance maxed for the "gods" you encounter in that act.

Sounds more than sufficient to beat act5 content.
Since you defeated Innocence already, your next big challenge is going to be act5 endboss Kitava.

This fight is dangerous if you dont know the mechanics and Kitava hits really hard.
But you are tanky enough to deal with it. As a rule of thumb you should be stacking 300hp per act, so you should be sitting at 1.5k life and you are at 2k already.
Res are capped as well, so except for Kitava only your own mistakes can kill you ;)

Make sure to check your res again after the Kitava fight.
In Act6 ele dmg kicks in and even with a large hp pool, you could die to ele dmg easily with uncapped res in act6.

Ele dmg really. that's it.

I've done SSFHC Jug the past 3 leagues. First with S&B Sunder, then with dual wield Cleave. I'm no PoE expert by any mean.

Act 6 - Try to Max fire res spesifically before leaving town. Build up cold and lightning to max by the end of the act. The boss isn't too bad if you got some regen and max elemental resist. I facetank it every time, but avoiding stuff helps.

Act 7 - The boss can take you donw if you don't avoid stuff, chaos res helps I think. Never died there.

Act 8 - The mid boss can be troublesome with low dps. Chaos resistance helps. Turn the valve when things get too tough to change the state of the fight. The end bosses can be difficult with low HP. You need to dodge stuff, but it shouldn't be too bad.

Act 9 - The different bosses here can take you down, but they are not hard if you have decent regen (300-400) and good HP pool, around 3,5-4k is what I usually have here.

Act 10 - The end boss is a real challenge if you don't know the mechanics. I don't go there with less than 4k health, try to get to a bit above that. Armor and physical resistance helps a lot. You need strong health potions here for the last phase, bring fire res potion with you and 1-2 Hallowed health potions with instant health recovery and maybe one potion with large recovery over time.

I've only ever died to Innocence in A5 and the A10 boss, those are my only concerns really with a Jug.

Biggest threat to the Juggernaut? Complacency. Thinking you can tank that when, clearly, you can't. "I'm the Juggernaut, bitch, I'll eat that slam and spit it out!" Nope. You're not supposed to survive that. Use your unstoppable powers and move your ass some place else. You're only near invulnerable. Near. Forgetting that will kill you like the leaf on the back of Siegfried.

Pay special attention to Aberath, Yugul, Solaris/Lunaris. Especially Yugul. To a lesser extent - A8 Doedre.

But ofc Kitava 10 is the most dangerous. Enter at no less than 4-4.5K HP and good damage mitigation.

Speaking in general, what fucks juggers all over is the heavy ele damage.
