Summoner immune to everything

Build

Made this build in HC back in blight. Back then was doing maps up to t16 without taking any damage but died to god knows what and stopped playing from disappointment till recently. Created new char this league and it is now even tankier. It has immunities to literally everything except freeze and stun. Well and maybe curses. Not immune to curses but has 100% effectiveness reduction. Lowest EHP is 230k. Highest single hit it can take is something like 200k. Maximum attacks block and almost maximum spell block. Can reach max spell block with different boots but then I will be loosing immunity to bleed and this is kinda not matching build theme. Minions are used to survive even in AFK mode. Spiders duration is 54.3 sesonds. DPS is a little bit low. With correct gems and some tweaks will be able to reach 1m shaper dps.

My priorities here were:

1. Highest possible tank I can achieve
2. Convenience. Most of defences should be automatic
3. DPS if possible.

It can survive almost anything including high ping and PC freezes. I couldn't find any build that will have more EHP (except for 1 with some unrealistic gear and need to use lots of abilities constantly).

It works well even on low budget with just Incadescent Heart (6l is just a luxury as Zombies here work just as a meat shield), Aegis and Cyclopean coil. So somewhere around level 68 it is already working as expected with like 70% effectiveness. Adding Memory Vault completes tanking capabilities and Araakali's Fang gives DPS and makes it much more satisfying to play. Also I could switch to Astramentis and anoint soul of steel to push EHP even more but this random amulet I got is surprisingly too nice and not worth replacing right now.

Only "weakness" of this build is damage over time. But not like real weakness. Just not enough regen to ignore dots entirely.

Gem setup for zombies is weak now. Until recent levels I couldn't resummon them without disabling some aura and they were dying some times in worth possible situations. I was also missing ring socket to add spirit offering to boost their resistances and needed to boost their survivability somehow.

Any suggestions on improving DPS or EHP even more? Just without sacrificing current tankines. Surprisingly it is more dangerous than it was in previous leagues and I start panicking whenever my ES drops below 80%.

EDIT: Video per u/amin7224 request. Forgot (or to be honest didn't cared enough) to switch spiders to melee splash. That would make it twice faster on map. Don't know why there is no sound. Sorry for that. Used highest tier map I had at moment. Can gather some sulphite and show delving. Or higher tier map. But it honestly looks the same.

One more thing I forgot to include initially. Build can do any mods. Literally. There are obviously some unpleasant mods bot nothing absolutely deal breaking.
