Ah the good times Switch guy. Rather easy, but not until I figured out that he just kept switching it back, dirty little rat. My archer hero made minced meat of his ever-summoning guards, explosive arrows in small quarters, but I kept seeing him up his life..so I stopped worrying about the summons. Which to my surprise essentially bogged them down in their own corners, to agro them I HAD to shoot them, so I left them alone and concentrated on Raze, once he was down to 20% or so I spammed my "e" key until he tried to use the lever.
Well after that he just stood there..sad boss indeed.
happy hunting
