Heiro/witch Totem build for Lake - ISO suggestions

I like the totem playstyle and was hoping their may be an endgame viable/uber boss killing build i could make for this upcoming league that would include both the new bitterdream and squire.

Would prefer going off of heiro or Witch. Would prefer to go with a good clearing skill. Would prefer to avoid brands and damage conversions to other elements (in order to keep the build simplified and scalable with gear). Heavy use of auras and gearing for reservation eff. Would prefer to not use any vaal skills or auras.

Open to the idea of stacking flat damage depending on the primary skill but kind of lost here since i rarely theory craft and prefer the mindless playstyle of dropping totems and cruising through content - problem with this is that when it comes to the endgame bosses i usually lack dps to nuke em and survivability to survive a couple hits which is where i hope to have the rest of my gear and auras help out.

Thanks for any advice.
