Auto-Bomber is a very specific type of build that utilizes Skills that are either triggered automatically or deal damage Passively. In practice, it should allow you to simply run through Maps without using any skills (obviously you will use some, otherwise you wouldn't be actually playing, would you?) while everything dies around you automatically. The following Herald of Thunder build is currently the best example of such a build that utilizes the Storm Secret Unique Rings that increase the frequency of Herald of Thunder's lightning strikes, and triggers them whenever you Shock an enemy. By increasing Herald of Thunder's damage, you basically can run around and kill most of the enemies with the HoT's Lightning Strikes itself. The mechanic itself is extremely fun to play, and with some investments in gear, you will be able to take down any Boss in the game. Overall, this build is quite expensive, as you need two Storm Secret Rings, and powerful Rare equipment to boost the damage of Herald of Thunder's Lightning strikes significantly - its base damage is rather low, so some investments is to be expected.

1. Gameplay

This is a very fast-paced build which ultimately allows you to run through Maps obliterating everything without having to stop to cast Spells. The core mechanic is based on increasing the frequency of Herald of Thunder's Lightning strikes and creating Storms via Storm Secret Unique Rings. The Ring will also deal a moderate amount of Lightning Damage to your character, which will trigger additional Spells (Wave of Conviction, Shock Nova, Cold Snap) via a low-level Cast when Damage Taken. The Wave of Conviction applies Lightning Exposure, Shock Nova offers additional Shocks to trigger extra Storms, and Cold Snap creates Chilling Ground so that you gain the benefits of Algor Mortis Unique Gloves. You also use Storm Brand solid additional damage and tons of Shocks procs, Orb of Storms to apply Curses (and also extra Shocks). All those Lighting Spells combined will trigger a lot of Lightning Damage from Herald of Thunder, dealing massive damage to enemies, but also to yourself. To mitigate it, a very strong defensive combination is used. This build utilizes both Life and Energy Shield (you should have approximately 4,000 of each) and offers both Life and Energy Shield Leech to quickly recover all the damage from Storm Secret Rings and enemy Hits. In order to make this even more efficient, you should use Glorious Vanity Unique Jewel, which should turn Mind over Matter into Corrupted Soul, which will make 50% of non-Chaos Damage bypass Energy Shield, so you should take around even damage to Life and Energy Shield simultaneously, allowing you to Leech both of them at the same time.

This video was recorded on a level 93 Assassin with 4,700 Maximum Life and 3,000 Energy Shield. We did approximately 500k with Herald of Thunder Hits, which easily lets you kill all the Bosses in the game with being able to heal through most of the incoming damage as well

3. Leveling tips

For leveling, you should use Storm Brand mainly. It's a fantastic Spell for clearing big packs of enemies, and it's one of the core Spells used in this build later on. You will be using Herald of Thunder as well, however, initially only to boost the damage of your Storm Brand. It still can deal some extra damage but with reduced frequency, it may not be worth focusing on entirely. Though if you have Calamitous Visions and the Lone Messenger, it's quite powerful even on lower levels. 

Suggested leveling Gem setups:

Storm Brand setup
Storm Brand Storm Brand - one of the two core Spells used in this build, which performs exceptionally well on lower levels. It deals massive AoE damage and has a very high Hit frequency
Added Lightning Damage Support Added Lightning Damage Support - adds a lot of Lightning Damage 
Controlled Destruction Controlled Destruction Support - greatly increases Spell Damage at the cost of reduced Crit. Chance
Inspiration Support Inspiration Support - grants high bonus Elemental Damage, Crit. Chance, and reduces the Mana Cost of linked Spell
Herald of Thunder setup
Herald of Thunder Herald of Thunder - core Herald Spell used in this build which hits nearby enemies with Lighting storms. You can either use it purely to add Lightning Damage to your Storm Brand, or add a few Supports and use Calamitous Visions so that it does slightly more damage on its own
Added Lightning Damage Support Added Lightning Damage Support
Elemental Focus Support Elemental Focus Support - greatly increases Elemental Damage of Supported skills but makes them unable to inflict elemental ailments (which Herald of Thunder can't do anyway)
Utility Gems
Orb of Storms Orb of Storms - it's a great addition to this build since it has high base damage, and on higher levels, you will be using it to apply Curses anyway
Conductivity Conductivity - the best Curse for this build. On lower levels, you can simply apply it manually against Bosses and tougher enemies
Clarity Clarity - grants increased Mana Regeneration Rate. It's very useful on lower levels, and you don't have to increase its level at all
Dash Dash - recommended mobility Spell

Bandits:

We recommend killing all the Bandits for two additional Passive Points. You can also help Alira for extra Crit. Multiplier if your level is high enough to pick up all the core Passives and actually benefit from it

35 Points Skill Tree
Priorities: 1) Blood Siphon 2) Coldhearted Calculation 3) Runesmith 4) Throatseeker 5) Written in Blood

5. Final Gems links

[DPS] Herald of Thunder setup
Herald of Thunder Herald of Thunder - the core Spell for this build which deals massive damage with Lightning Storms and at a greatly increased frequency

Added Lightning Damage Support Added Lightning Damage Support - grants high bonus Lightning Damage to your Herald of Thunder hits. You can also use the Awakened version here
Power Charge on Critical Support Power Charge on Critical Support - grants very high bonus Damage per Power Charge and high base bonus Crit. Chance. Since you are an Assassin with 7-9 Power Charges, this is one of the best  Supports for this build
Lightning Penetration Support Lightning Penetration Support - makes HoT ignore a large portion of monsters' Lightning Resistance. It also has an Awakened variant
Inspiration Support Inspiration Support - grants increased Elemental Damage and Crit. Chance while the Inspiration Charges are built up via Storm Brand since you don't spend Mana on the Herald itself
