best boss killer build, even uber bosses

hi, which build is best for kill all bosses in game? be very very tanky, have big damage, build cost not matter, few mirror is fine.

Poison SRS is always a great go-to.

Although, for uber bosses and bossing in general it's actually less about the build and more about your knowledge of their mechanics.

Sure, there are builds that "cheese" some of the insta-death stuff. But I don't think there's any build that cheeses ALL of them (could be wrong). You need to actually know what you are doing too.

If you have enough damage to insta-phase a boss before they can use any one-shot mechanics, I guess you don't need to bother learning them. For a build that can both insta-phase and afk every uber boss, I'll let someone else answer. I don't have that experience.

I mean if your budget is a few mirror why arent you just making an armor stacker?

Armour-, life-, mana- or ES/EV-stacker(new this leageu) are the 4 buildtypes that come to mind if you really want to spend mirrors.

I did an attribute stacking Penance brad of dissipation. have like 26k ES, like 15 with energy blade active. Pretty much isnt kill anything.
