PoE Choir of the Storm, Chaining builds

What's the idea here? Choir of the storm, perfect form, formless inferno and Perseverance are your key items. From there you stack resistances by getting flask effect and res flasks, the build gets ~500% overcapped resistances What my PoB attempt at this achieves: - 80k armour - 80k evasion - 98% crit chance - ele ailment immunity - bleed and corrupted blood immunity - stun immunity - curse immunity - permanent 150% movement speed - 20% less elemental damage taken - Fortify and onslaught when mapping What my PoB attempt at this is lacking in - only 3k life and no real way to recover

I am working on an assassin static strike character as a potential league starter for 3.16. I would like for it to be a bit tankier but can't figure out how to get that into the build, any ideas on how to get that set up? &x200B; Also more damage would also be nice, as I can't seem to squeeze anymore in.
