Trial of Sekhemes struggle as Warrior

Looking for tips and tricks for the Final Boss, Rattlecage. I havent looked up and anything for Builds, Weapons or Spoilers. I want to do this my way as much as possible but this is starting to get to me and so I am here looking for advice.

Also side note of something completely different. Is there a known loot table for bosses or good farmable areas per Act, to get gold or gear?
