PoE 3.22 Ancestor, 3.21 Crucible, 3.20 Sanctum Ulaman's Gaze builds

Its my first time making a build from scratch, wanted to make an abyss stacker but i don't personally like the look of the rathpith ones so i tried to make one myself. Can anybody spot any glaring issues or problems i might face? (Such as I'm a little worried about mana but from what i can tell, it looks fine) Also, i notice nothing changes when i flick arcane surge on and off. Makes it really difficult to know if i will have mana problems because i have no idea if the stated regen is with or without arcane surge. I'm aware that it would have trouble bossing but that's fine as my other build

I was planning on going lightning arrow champion when I saw this post on r/PathOfExileBuilds, In the comments I saw this question from d2WarlockNeedsLove asking if Voidbringer could be used to prevent Lightpoacher from triggering the skill and consuming spirit charges\\:\\ [

Right before patch notes, I figure I'd share another build I've been working on. One unlikely to get bonked, because it's so off-meta. Note that this isn't the final PoB, and more optimizations are in the works. The question of "how many blades" can I generate per-second has always been a fun to explore with Venom Gyre. But recently, I realized I was asking the wrong question: Just how many of the returning projectiles can I get to hit? This build can hit a single solo enemies with approximately 84 Returning Blades per second. Pob here: Explanation below.
