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 it either
• only ~400k sirus dps
• weak against chaos damage, particularly spells/dots
• doesn't hit attribute requirements

The PoB

Care that the PoB is very much not as good as it could be, i'm not good enough to make a proper one, this is why i'm making this post at all, so i can hopefully pass the idea on a player that is better than myself

Skill choice

No real reason why i've chosen lightning strike, honestly i was lost on what skill to use and i'm sure you guys could figure out a much better skill for the build. The weapon is a copypaste from a poe.ninja weapon for lightning strike
