Uber pinnacle bosses

Hello,

I think im one of the mediocre player of this game. Have played 7 - 8 leagues by now with breaks. I understand mechanics about this game and usually in the league i level one char to 90+ level, sometimes ... it depends how the league is fun for me i play more or less ... . Ussually im having good gear with some of the endgame items like Mageblood / HH or if the builds need sometink special im having it.

Im okay with the fact that im not the 1% of players what are really good of this game to get to the level 100 or do the 40/40 achievement. On the other side i really like doing bosses.

I like the style:
1. Farm fragments / invitations / map drops
2. Do the boss
Repeat

I dont mind if its profitable or no for me. From time to time i will get good drop from the boss what i can sell for some divs and thats it. Im okay with that and i have fun. But i sux on the bosses:D Im just slow with reactions. If there is somethink on the ground what should i not stay in it i will stay there for some time etc:D. Sirus say DIE!!! and i will get the first hit with beam and then dodge.

In the past every time new boss came out it was big wall for me. It took me ussualy whole league to learn the mechanics for the boss and after that it was fine. I like the learning about the boss fights - dont mind if i lose 6 portals to fight, if i see Im improving myself in the mechanic of the fight with boss.

Now im in state a can kill not the uber version of every boss in game every league. Cause i have learned the mechanics and can dodge them. Sometimes more succesfull and sometimes less with some deaths. Like for example i cant kill maven with 0 deaths - the fight its just too hard for me - last phase.

But with the uber bosses variants im quite lost now. Every time i try to learn them its just oneshot in less then 10 seconds in the fight. Its okay to die and learn the fight but im really not progressing with the learning curve. Every attempt its for me just 6 portals = 6 deaths with basically first what the boss throw at me will kill me:D What i want now its actually have chance to learn the fight with chance to kill the boss.

Can you please help me to suggest build what is capable of:

1. Farm red maps - dont need to be super juiced maps at mediocre speed.
2. Allow me to learn the uber pinnacle boss fights with staying alive. Im ok if somethink kill me from time to time. Or do the fight with one portal left. Just want to be not oneshotted by everythink:/ with afordable items requiremnts - 100 divs lets say.
3. Have damage to kill the pinnacle boss (not nuke in seconds).

Or any help suggestion how do you do the uber version of bosses?

Sorry for long post - i did it because i wanted to let you know what is my "gaming level/experience in poe" because it is maybe and i have the feeling now that the uber version of bosses its just "out of my league" of trying. I will always be hit with somethink ... always reacting a little slow.

It is possible they are designated for better players than me and im okay with that. I will never be "that guy" who can clear all content with 1 div build. POE is still fun for me from time to time, i will just change my goals for league:)

How did you managed the uber bosses?

I'd recommend some kind of tanky pathfinder build. Either using physical conversion (Lightning Coil/Cloak of flame + Dawnbreaker) + transcendence or Tempered by War + mahuxotl. Both can get to a point where you can just stand in most uber boss mechanics without taking damage. The defensive gear required isn't very expensive so the cost mostly depends on how much damage you wanna do. Progenesis is great on those builds but not required. The skill you use doesn't matter all that much but poison is a good way to get decent dps for cheap and has synergy with pathfinder.

I've beaten all of them this way. If they can't kill me then my victory is just a matter of time. I also got a PF to do it but i mostly use an ascendant molten strike build or a shield crush juggernaut.
