[Feedback Requested] 3.21: Bow-Based Double Lightning CoC Sabo - Solid Mid-to-Late Game Build?

PoB: https://pastebin.com/eS1VKxtQ

I'm currently trying to build around the new Saboteur Triggerbot changes and came up with a Bow-based CoC build. I wanted to try something outside of the usual Frostbolt / Ice Nova / Ice Spear variants, so I gave lightning a try with Arc + Voltaxic Burst and Shock Nova in Asenath's for BIG shock support. A few notes on the build:

• Built gear to be "Good, but could be better". Lots of places for optimization
• ~36M PoB DPS, but it probably floats more around 25M-30M DPS realistically given missed arrow procs, sub-optimal trigger rates, and Triggerbot positioning
• Passable 30K Effective Hit Pool with 73% Evasion, ~30% Chaos res, big chills/damage reduction from Call of the Void, and high life regen from level 21 vitality + leech to balance Petrified Blood
• Poison and Bleed immune with the Tolerance tree cluster + abyss jewel (I always try to stuff this into builds - feels really nice, especially for Expedition)
• No Mageblood / flask for mana costs - 218 unreserved mana with regular Inspiration, mana leech from Blast Rain / Rain of Arrows, level 21 Clarity, 2 -mana crafts on jewelry, clarity -mana Watcher's Eye (with no other mods), and new 'Skills cost Life instead of 30% of mana' notable
• ~90% crit chance without flasks or Brittle, reliable procs even when bossing

Arc seemed like a good clearing candidate since it can chain from the enemy nearest to the Triggerbots. One big worry I had about a bow CoC build is having Triggerbots behind me and my projectiles ahead of me. Waiting to see how this feels, but I'm confident it should be alright.

Voltaxic Burst has great synergy with double triggers, given the line '1% more Damage with Hits and Ailments for each cast of this spell currently waiting'. With a PoB trigger rate of ~9.43 per second (which should be doubled with 2 triggerbots) and a duration of 2.5 seconds, we could theoretically have a 47% more multiplier on VB's damage. I set it at 30 casts to be conservative. Also, I just ignored the 40% lightning to chaos conversion since it was too difficult to build around otherwise.

I thought about running Voltaxic Rift for my bow slot, but you get so much more from a rare Shaper bow:

• CoC as a 7th link (which means ~30%-40% DPS from another support gem)
• +1 to Socketed Gems, which works well with Empower and Arc getting +1 chain at level 26 (which also means more single target DPS given Arc's wording)
• Essence-crafted 130% inc spell damage
• Increased attack crit chance compared to Voltaxic, which means we can drop +Attack Crit% from our body armour
• Using an Ivory Bow instead of a Spine bow drops the dex requirement to 152 instead of 212 (which is otherwise a drag to get) - same crit / AS

Honorable mention to Call of the Void: It allows your lightning / chaos damage to Chill, which fulfills the requirement for Explosives Expert. It also allows you to Shatter, which means no Porcupine worries (might want to swap out Awakened Ele Focus for Awakened Added Lightning for mapping). Felt like a great addition to the build.

Please give me some feedback about the build! Pay attention to the custom modifiers - I tried my best to work around PoB limitations (Blast Rain procs, triggerbot damage, Call of the Void damage mitig, and 55% low life mastery). I'll be happy to answer any questions you may have.

Good luck on Friday Exiles!
