[No longer playable] Self-Shock Galvanic Field - A Reverse Snapshotting Autobomber

Build is no longer playable due to the removal of reverse snapshotting and archmage no longer working on orb skills



Introduction
This is my take on a speedy autobomber that scales exceptionally well. The build revolves around two mechanics: self-shock Galvanic Field for the autobomber playstyle and and reverse snapshotting to scale our damage.

Pros & Cons

+ Extremely fast and strong mapper
+ Autobomber with explosions!
+ High scaling potential
+ High damage uptime and projection
+ High ehp pool and recovery
+ No temporary league power is used in any of the showcases (see tab for league specific suggestions)


- Not SSF viable (requires Indigon and Battery Staff at least)
- Not HC viable (at least without some adjustments)
- Permanently 65% shocked
- Complicated to put together
- Requires ~5 divines to start

Affliction League Specific
Spoiler
I highly recommend Wildwood Primalist as there are excellent charm modifiers for this build. Some standout ones are strength + intelligence, % increased strength, % mana/energy shield/life on kill, mana as extra energy shield, chance to gain onslaught/phasing on kill, culling strike and elemental resistances. Also worth looking for a That Which Was Taken, prioritizing the same modifiers.

Build Mechanics

Spoiler
Self-Shock Galvanic Field
Spoiler
The core idea behind this is get Galvanic Field to stick to us instead of an enemy.

Once we have the Galvanic Field buff(see Triggers), we need to stick the field to ourselves and not to an enemy. To do that we need a way of hitting ourselves and inflicting a shock with that hit. We can hit ourselves with Storm Secret, but that damage has no inherent chance to shock us (our own chance to shock doesn't help here). To remedy this we can use Replica Reckless Defense, which gives us a 10% chance to be shocked when we're hit with lightning damage. Now we've got a Galvanic Field that follows us around!

Large Self-Shocks
Spoiler
Unfortunately (or fortunately maybe), Storm Secret doesn't hit us hard enough to inflict a large shock, meaning the damage and area of effect won't be as large either (see Self-Shock Galvanic Field). Luckily, Galvanic Field only cares about the size of largest shock on you, not the size of the shock inflicted by the hit on you, meaning we can use Vessel of Vinktar to get a 50% shock on us (see Maintaining Vessel of Vinktar). But we can do better than 50% shocks. With the lightning mastery we can get +15% to maximum shock and reach that maximum shock by getting at least 30% increased effect of non-damaging ailments (Ash, Frost and Storm).

Maintaining Herald of Thunder without Shocking Enemies
Spoiler
We need to maintain Herald of Thunder in order to continue to trigger Storm Secret's self hits, but we can't hit and shock enemies (see Ways to Brick this Build). Instead we need to find a way to shock without hitting. Fortunately, Vessel of Vinktar solves this problem too by causing nearby enemies to be shocked, allowing us maintain Herald of Thunder and our Storm Secret self hits (see Maintaining Vessel of Vinktar).

Maintaining Vessel of Vinktar
Spoiler
We need to maintain Vessel of Vinktar for this build to function (see Large Self-shocks and Maintaining Herald of Thunder). To ensure we have constant uptime on Herald of Thunder we need less than 6 seconds of downtime which we can achieve with the Essence Extraction cluster, The Traitor Timeless Jewel Keystone and a well rolled Vessel of Vinktar(less than 140% increased Charges per use). This requires us to drop all flasks except one Quicksilver Flask (because we want to go fast and it can provide a lot of resistances).

Reverse Snapshotting
Spoiler
Reverse snapshotting is a way of getting all the upside of Indigon and Archmage without having to deal with unsustainable costs.

To do this we start by casting Galvanic Field linked with Archmage at a relatively small cost. Immediately after that we cast Arcane Cloak, spending a large portion of our mana and causing Indigon to massively increase the mana cost of our skills (see Managing Mana). This causes the cost of Galvanic Field to skyrocket and thus the damage thanks to Archmage and Indigon, even though Galvanic Field was cast when its cost was low. This works because the damage of duration skills are dynamically updated rather than being snapshotted when cast, hence reverse snapshotting.

Battery Staff
Spoiler
Archmage and Indigon give us quadratic damage scaling with mana. Unfortunately, even the lowest level Arcane Cloak will make our mana costs exceed our maximum mana. Fortunately, if we use the Battery Staff (or Reciprocation Staff) we can also count our energy shield as mana, allowing us to scale the cost and damage of Galvanic Field even higher!

Managing Mana
Spoiler
To maximize our damage we need to spend enough mana to boost our costs to slightly below our maximum energy shield and mana pool every four seconds, which we can do with an appropriately leveled Arcane Cloak (see Reverse Snapshotting and Triggers). This formula roughly tells you the highest percent of mana your Arcane Cloak can spend where e is your maximum energy shield and m is your maxiumum mana: (.78m + e)/(.00058 m^2). I recommend subtracting 5-10% from this value to give yourself a buffer to account for initial mana spend and potential damage taken. Here's a calculator that can calculate all these values for you:
https://codepen.io/justinryder/full/mdoKdqO.

As an example, if we have 6000 mana and 9000 energy shield, we get (.78 * 6000 + 9000)/(.00058 * 6000^2) = 0.66. Then we subtract 0.1 for the buffer to get 0.56. That means we'd want a level 12 Arcane Cloak since it spends 56% of our mana.

If this number tries suggests a number above what even the maximum level Arcane Cloak would spend then just use a level 20/21 Arcane Cloak. But if even a level 1 Arcane Cloak spends too much mana, then you need to decrease your mana to energy shield ratio. This can be done through gear alterations or, more simply, by reserving some mana. I recommend Defiance Banner (10%), Flesh and Stone (25%), Blasphemy (35%) or Wrath (50%) depending on how much reservation you need.

Triggers
Spoiler
Reverse snapshotting manually is difficult (also Galvanic Field has a cast time which would slow us down and cost us uptime on the Indigon buff), meaning we need a way to trigger our skills automatically.

Since Arcane Cloak is an instant skill, we can bind it to left click and have it automatically trigger whenever its off cooldown(see Managing Mana). We can get the duration + cooldown(guard skills' cooldowns only start once they've expired) to slightly more than four seconds (~4.2 seconds) by linking to Less Duration and Swift Afflication and taking reduced cooldown of guard skills on the passive tree. Next we need to cast Galvanic Field no more than once every 4 seconds and no less than once every time we cast Arcane Cloak. The way we do this is with the veiled modifier "Trigger a Socketed Spell on Using a Skill with, a 4 Second Cooldown" (the crafted 8 second version can work on high budgets if you are very, very careful with duration and cooldown recovery). Since we use Arcane Cloak slightly less than once every 4 seconds, each time we cast Arcane Cloak we trigger Galvanic Field and, since things being triggered happen before the thing doing the triggering, we will trigger Galvanic Field at a low mana cost and then Arcane Cloak will immediately ramp our mana cost and damage, perfectly minimizing Indigon downtime and providing a smooth autobomber playstyle.

Strength and Intelligence Stacking
Spoiler
Since we scale our damage off both mana and energy shield, we also stack intelligence as it increases both energy shield and mana (see Battery Staff). Shaper's Touch allows strength to also scale both mana and energy shield as well as providing increased damage with Iron Will and extra energy shield from Ivory Tower. Finally, at a very high budget we can use Forbidden Flame and Flesh for Righteous Providence to scale our critical strike chance with strength and intelligence.

Pantheon
Spoiler
We use Brine King to mitigate stuns and chills and for freeze immunity. Lesser pantheon is optional but I recommend Gruthkul, since we can permanently maintain maximum stacks.

Ways to Brick this Build
Spoiler
Hitting with a skill not linked to Elemental Focus (except Galvanic Field)

Having any source of explosions not already present in the build (only exceptions are Inpulsa's Broken Heart and Herald of Ice)

Having any generic cooldown recovery (unless you are extremely careful and using the 8 second trigger craft)

Any source of increased flask charges used or flask charges lost when hit (from Searing Exarch Altars)

Running maps with the following modifiers: reduced buff duration, reduced cooldown recovery rate, elemental reflect (also chance to avoid elemental ailments if you have enough increased effect of map modifiers to reach 100%)

Having any more than one flask other than Vessel of Vinktar (or zero if you don't take Essence Extraction)

Chance to avoid/immunity/unaffected by shock (even reduced effect will heavily cut into your damage and area of effect)

Arcane Cloak's cooldown + duration being less than 4 seconds

Having the cost of Galvanic Field after Arcane Cloak be more than the sum of your energy shield and mana(can check by hovering over in hotbar and I recommend a buffer as well, see Managing Mana)

So much increased area of effect that Galvanic Field's becomes significantly larger than Herald of Thunder's

Galvanic Field's duration being too short (aim for a duration of 6 seconds with 2 Replica Reckless Defenses or 8 seconds with 1).

Spending more than 400 mana every 4.5 seconds (can get away with more but you will start to really chunk your energy shield every 4.5 seconds)

League Start, Leveling and Transition
Spoiler
Leveling as the standard fire templar, which is always excellent on league start and doesn't require any respec points outside what we get from mainline quests. We use Holy Flame Totem + Flame Wall before we get Armageddon Brand + Cremation. At some point you'll need to farm currency, can either stick with Armageddon Brand(Armageddon Brand of Recall is quite strong) and slowly farm up a few divines using either heist or Essence/Beast Farming in white maps or you can just play an actual league starter until you have enough currency to transition

Leveling POB: https://pobb.in/Bslv6eVwC5Uh

Transition when you have enough currency to afford the mandatory uniques (depends on economy but has never been more than 4 divine day 1 or 3 divine day 3) and have a Battery Staff with "Trigger a Socketed Spell on Using a Skill with, a 4 Second Cooldown" (generally takes ~1 divine worth of veiled chaos orbs). Recommended items should generally be your first upgrades.

If you're interested in an autobomber league starter with explosions try Vengeance Ignite Autobomber

Don't think so unfortunately, as the flask we most need to sustain is unique.
it's all fun and game until you committed sudoku with flamedash
and why not battery staff ? why the lower base of it ?

Whoops, high key thought they got rid of the different tiers of the experimented base types this patch. Changing everything to Battery Staff now lol, nets us a few hundred more energy shield. Flamedash itself isn't inherently dangerous to us, what your probably seeing is my CWDT setup triggering too frequently and ramping all our costs (still playing around with the level of CWDT)
Hey, how can i craft that staff bro? Veiled chaos orb only?

i'm 100% sure that i dont use cwdt, and i dont seems to reach 65% shock effect, stucking at 50% from vinktar even tho i got lightning mastery with 15%

That's how I did it, just spamming veiled chaos orbs. But if you want other modifiers besides the trigger (can roll massive flat mana, strength and intelligence), Aisling is probably the way to do it.

For the 65% shock you also need 30% increased effect of non-damaging ailments (the build uses Ash, Frost and Storm, see Large Self-Shocks section of Build Mechanics).

Hard to tell exactly why that's happening without a POB, the mana cost on flamedash shouldn't be over 200 even after you arcane cloak. Maybe you're not taking the Dreamer cluster (see Ways to Brick this Build)? The build has a lot of non-obvious requirements to function, I'd recommend copying the passive tree exactly before making any changes.

Very interesting build. I can't help but wonder why you're not using Replica Winterheart to get Unaffected By Shock? Shouldn't this give you the upsides of shocking yourself without the penalty of making you take 65% more damage from shock?
