Bossing: The Elder Slayers, The Formed, and the Shaper

I had to build a second character in order to beat the bosses in the game. Between this league and the last I have come to an understanding as to why people make multiple characters. I don't like to do so personally but unless I rebuilt my Caustic Arrow Raider there was no way I can clear the bosses with that character. The damage is not focused/concentrated on like this build. Unfortunately this is my 3rd character for the league which is rather unusual for me. Leveling this was a reminder of why I prefer to play non melee characters while leveling. This was so efficient running through maps and needed very little gear.

This build is very much incomplete but that is what I am currently working with. I used several sources to put this build together from browsing poe ninja. The main source of information I was was @Balormage He was a ton of info on SRS in general.
