Done with Righteous Fire, need advice

What is a character/build that can push up to Uber Elder and stuff like Maven, Sirus (not the Uber versions) without having to invest dozens of Divines? I ask this because my RF has reached a point where I can't do certain bosses without more heavy investments.

I mean it, this is my last league playing and I would like to take down at least the "easy versions" of those big bosses just for the satisfaction, but I don't have time nor patience to spend days or weeks farming divines.

Can it be done? If so, how? My favorite characters are Scion and Duelist but so far I haven't found a cheap bossing build for those.

My current budget is 2 Divines + 300 c + lots of stuff I could use to craft or sell. If you help me on this I could give you some for free before I leave, I won't use it anyway.

Best way to spot builds that are low cost and have good dps are the ones used in SSF HC boss rush races. Elementalist Detonate Dead, Juggernaut Boneshatter, Cold Dot builds to name a few. https://poe.ninja/builds/ancestorhcssf/

RF Jugg is also one of the easier ones to take down non-Uber bosses so there might be something wrong with yours (build or gameplay wise).

Yeah you are already one of the best builds to do this. I did RF Jugg a few leagues ago and it was pretty easy, but slow to do all the pinnacle bosses. You are so tanky that as long as play defensive and avoid slams/degens you can do it all. Fire trap in a elder helm with 30% more ele and Burning and/or Conc Effect carries your bossing daamge.

But if you're wanting a build only to focus on bossing, DD elementalist. Hexblast mine, Impending Doom PF, Cold Dot Ele.
