Need help to take down Uber Elder and Maven

If anyone is interested in helping me take down the end bosses so I can get the map bonuses it would be much appreciated. I am unsure where on this board to post a request like this so I am doing it here. Feel free to send me Xbox Account a PM with friend invite and I will message you when I get on this weekend.

I can handle all other content in the game but these 2 just crush my build. This is on STANDARD SOFTCORE by the way. Thanks!
