I took https://youtu.be/EG9QD9wXnFI updated it to 3.21, replaced the PoB-made items from trade, messed with it a little bit to arrive to https://pobb.in/4ZkjeGda-PJP

Deals damage, is ailment immune, corrupt blood immune, has 50k eHP against Pinnacles (not that I think it's a good idea to use this against Pinnacles but maybe your voidstones). Oh and runs at 288% inc MS without flasks. Aside from the 6L chest and bow, I believe no items here should cost a divine. Most are quite a bit less.

I really would love to know how to get more phys mitigation.
