Permanently 100% all damage immune Flaskfinder [Theorycraft]

Anyone made a PoB?

For the Immune to Elemental, have you tried Blood of Corruption (Gluttony of Elements), Soul Ripper Flask (alternate with Gluttony), increased duration stacking, Self-curse Shackles of the Wretched Temporal Chains if more duration needed? Or has anyone done the math on this? Then you don't need max resists or resists at all.
