Forbidden Rite Poison Self Cast Pathfinder (poisondamage up to dps cap & tanky)

I wanted to pair pathfinders def + tempered by war + mahuxotl machination (MM) last league but couldn't overcome the fact, that you cant regenerate life and the recovery by then (6% per flask) wasnt enough for me.

This league this problem was solved by the PF rework, since life flask recovery isnt blocked by MM. So i started with TR and transitioned as soon as i got MM and a replica Sorrow if the divine.

I have choosen FR just because its a cool fit, not because its the most potent skill.

This is my current progress: https://pobb.in/A5V-QFwHJWrJ

This is what i aim for so far: https://pobb.in/nfgmODRASxf9

The defensive highlights are:

• 85% all max res
• 3800 life recover per sec
• 25k phy max hit - 68k with IC (50% uptime)
• Not effected by lightning & cold pen

The concept here is to take all lightning and cold damage as fire and chaos damage and to further mitigate this damage with at least 85 max res & 30-40% less damage taken (ruby flask + Doppelgängers guise). The physical mitigation is done by 35% of physical taken as fire + 40% less by DG + 3 endurance charges + ca 50% uptime on immortal call.

Replica sorrow of the divine takes care of mana problems & enables 100% uptime on everlasting sacrifice

The self hit by FB enables 100% uptime on endurance charges with enduring composure and triggers despair + temporal chains on sturdy bosses/rares.

In my current version i have 17mio poison dps if all primary projectiles overlap, but since its a poison build, it needs ca 7 secs to rampup - so the real dps is lower. In the endgame pob you can reach the dot cap of 36 mio (but again poison dps needs rampup, but this build provides you with the defenses to stand still and cast)

Im open to any suggestions and will happily answer any questions :)
