PoE 3.22 Ancestor Arcane builds without Ancestral Cry

Path of Building question... as I scrolled past the "Precision" notable on the skill tree I noticed a huge bump in DPS which caught my eye. Was a bit surprised though because I am playing as a manabond hiero with cyclone + arc, so really spell based. I don't recall global accuracy being meaningful to spells. This notable plus the minor before give +10% cast speed as well but was skeptical that addition would result in \~13M+ additional damage. From what I can tell the trigger rate for manabond increases resulting in the higher dps. As a comparable test I added +10% cast speed on a dummy tes

No MoM, instead stacking reduced cost of skills to bring manabond cost down to zero, then permanently having 0 mana via Shavronne's Revelation + a Manastorm shield weapon swap. The max lightning res stacking was intended to support Shimmeron but it turns out a 2nd Void Battery is more damage anyways, so may do away with that part of the build.

383k x 9 = 3,447 kk per combo rune blast cost = 282 mana/s cost of 9 improved runes to +3 = 135 ~2 combos per second = 6,89 kk you wouldn't be able to get this combo perfectly, so i assume ~5-6kk dps is more realistic. potential upgrades/switches Forbidden Flame/Flesh combo that gives Arcane Blessing Watcher's Eye with Spell suppresion and inc damage to enemies on consecrated ground
