I haven't invested in AoE upgrades to get Blades to overlap for maximum dps yet so I kept the blade amount in PoB as 1.

PoB: https://pastebin.com/HbByzKgM

With 10 power and frenzy charges, this build currently reaches close to 2 mil dps per blade with Bladefall throwing 45-55 blades per cast. To showcase the ridiculous bossing damage this gets up to: https://www.youtube.com/watch?v=aNGIE1EpIyc&ab_channel=PoeStuff

This was 3 BF BB casts for an elder on 15ex budget.

Build gets up to 4k life, i could fit purity of elements for ailment immunity.

30% dodge from elusive and crit immune (30 cuz 10% inc per frenzy from badge --> 100% inc from 15 --> 30)

Mana isn't an issue. One 3% spell leech as ES + eldritch battery lets us reserve pretty much 100% of mana (yes, my mana flask is useless i have it for bleed immunity)

Im still level 88, upgrades can bring this damage up horribly high (50 blades overlap with flasks reaches over 100 mil rn)
