Tornado Blade Vortex Autobomber - Automation League Starter


Introduction
This is my take on a fast autobomber with great scaling! The build revolves around using Automation to trigger a 100 mana cost Plague Bearer which triggers spells in Kitava's Thirst.

Mercenaries of Trarthus League Specific

Spoiler
For mercenaries I recommend either a Manyshot with Hatred (swap your Hatred for Zealotry) and Grace or a Bladecaster scaling Aspect of the Spider, making sure they don't use a curse that overwrites yours. Then for itemization I recommend capping their resistances with rares and either a rare helmet with good damage modifiers (nearby enemies take increased cold damage/have reduced cold resistance) or blood price.

Build Mechanics

Spoiler

Plague Bearer Automation
Spoiler
This build is constructed around constantly triggering a 100 mana cost Plague Bearer to trigger skills in Kitava's Thirst. Plague Bearer is an instant skill, which means we can support it with Automation to trigger it everytime it comes off cooldown! Since Plague Bearer costs 100 mana (see Scaling Mana Cost), that means Kitava's Thirst has a 50% chance to trigger all the skills socketed in it without us having to cast a single skill ourselves! On top of the smoother gameplay, this lets us have permanent Phase Run for even faster mapping.

Scaling Mana Cost
Spoiler
Plague Bearer by default has a very low mana cost (13 at level 20), which means we need to scale it quite a bit to cost 100 mana for Kitava's Thirst. The first way we scale the cost is via support gems. Plague Bearer can be supported by a handful of support gems, but all of them (outside of Automation at 150% and Concentrated Effect at 140%) have cost multipliers of 130%. This means in a six link the mana cost is 13 * 1.3 * 1.4 * 1.3 * 1.3 * 1.5 = 59, which means we need to increase the mana cost even more.

On league start we continue to scale the mana cost with Fevered Mind, which is a jewel that causes notables in a small radius to be replaced with 20% increased spell damage and 10% increased mana cost. Since we need to get a 59 mana cost to at least 100, we need at least 59/100 = 59% increased mana cost. So we need to allocate either 6 notables in a small radius of Fevered Mind or 5 and take Forethought.

After league start we can free up the jewel sockets and passive points by using reflected mist rings and amulets with the inverted modifier Non-Channelling Skills Cost +# Mana (make sure it's this specific modifier when searching on trade, its a different name than the non-inverted modifier). These rings and amulets are often cheap, since for other builds these are often failed reflecting mist outcomes. Non-Channelling Skills Cost +# Mana is applied after support gem multipliers but before increased mana cost (note that the game rounds down after the support gem multiplier calculations). This means with Forethought we need a total of 28, since ceil(100/1.15 - 59) = 28, of Non-Channelling Skills Cost +# Mana (can also get some effective + mana cost by increasing Plague Bearer s level via Empower/Corrupting/+ gem levels).

Mana Recovery
Spoiler
Now that we've got Plague Bearer spending 100 mana per trigger, we need a way to sustain our mana. Since we're scaling mana cost, the spells in Kitava's Thirst and in our second utility Automation setup cost quite a bit of mana and depending on the stage of the build works out to spending 300-400 mana per second on average. Since mana costs fluctuate heavily second to second it's important to have a decent amount of mana unreserved to act as a buffer (I recommend at least 250).

To sustain our mana we rely on our Lightning Golem and the extra mana sustain from Mastermind of Discord. We scale golem buff effect with Liege of the Primordial and Golem Commander (and eventually quality on the gem) and mana regeneration rate on the tree and gear (can be rolled/crafted on jewelry, wands and shields). Even with all these sources it's important that Blade Vortex has a higher socket priority (highest priority is top left then descends via the same path as sockets connect) than Tornado of Elemental Turbulence in Kitava's Thirst, since if we do miss a cast due to insufficient mana it's preferable that it's Tornado of Elemental Turbulence since maintaining maximum tornadoes is significantly easier than maximum blades (see Skill Choice and Duration and Cooldown Recovery).

Skill Choice
Spoiler
Kitava's Thirst has a 50% chance to trigger all socketed spells every ~.5 seconds (see Cooldown Scaling and Duration). This is a relatively high average trigger rate of 1 cast per second but has high variation, frequently going multiple seconds without triggering skills, making non-persistent skills unreliable for clear. Since Kitava's Thirst triggers all spells, we want to run at least 2 spells in it since the second spells is effectively a 100% more damage support if they both scale the same (a third is effectively 50% more damage, but mana cost and scaling differences make it a less obvious decision). Luckily, Blade Vortex and Tornado of Elemental Turbulence are both persistent skills and can be scaled similarly (physical to elemental conversion).

Duration and Cooldown Scaling
Spoiler
To maximize Blade Vortex and Tornado of Elemental Turbulence damage we want to have 3 tornados and 10 blades up as much as possible. Unfortunately since Kitava's Thirst doesn't guarantee a trigger every time we spend 100 mana, we can't guarantee 3 tornados and 10 blades. But by scaling cooldown recovery rate and duration we can get our average tornados close to 3 and blades close to 10.

We scale duration on the tree via Potency of Will and Exceptional Performance and the mastery for 10% more duration. Cooldown recovery we get primarily from the belt and boots(eldritch implicit). The relevent breakpoints for cooldown recovery are 2%, 9%, 17% and 27% (note that it's often worth sacrificing breakpoints in exchange for power elsewhere e.g. Mageblood).

Rathpith Globe and Dissolution of the Flesh
Spoiler
Note that this section only applies to mechanics introduced partway through build progression (see Upgrades).

Rathpith Globe lets us scale our damage with our maximum life, with the drawback of sacrificing life every time we use or trigger a skill. This is a great way to scale damage and defenses simultaneously, but we trigger skills extremely frequently, making it very difficult to sustain the life we're sacrificing. Fortunately, if we also use Dissolution of the Flesh we convert all incoming damage to life reservation, essentially meaning our current life no longer matters only our unreserved life. Since sacrificing can't ever reduce us below 1 life, we can safely sacrifice all our life! Since we're always at around 1 life, we can also allocate Pain Attunement for even more damage!

Dissolution of the Flesh only lets us remove life reservations when we haven't taken damage for 2 seconds, which makes degens very dangerous. To deal with them we use Stormshroud and two abyss jewels with 50% chance to avoid shock (eventually flask modifier post-Mageblood) to become ailment immune, use a flask to remove bleed and corrupted blood (eventually abyss jewels post-Mageblood, also lets us be poison immune) and Pantheon to become immune to Burning Ground.

Overlapping Unnatural Instinct and Light of Meaning
Spoiler
Note that this section only applies to mechanics introduced partway through build progression (see Upgrades).

Light of Meaning is a jewel that causes all passives in a large radius to also grant 8% increased physical damage alongside their original bonuses. While this is nice, it's often impractical to allocate large numbers of small passives. However, by overlapping Light of Meaning's radius and Unnatural_Instinct's radius, which grants the bonuses of all unallocated small passives at the cost of not granting allocated small passives, we can get a large amount of increased physical damage along with all the other bonuses of the valuable small passives nodes in the area to the left of the scion start, including duration, area of effect and mana regeneration!

League Start, Leveling and Transition

Spoiler
Leveling as cold DOT, which is always excellent on league start. We use Freezing Pulse into Creeping Frost before we get all the cold DOT gems. Don't forget to buy the gems from the Skills section from Lily in act 5 and leveling them in your off hand (note that most gems don't need/want to be high level)!

Leveling POB: https://pobb.in/QkR1t0pc5Xz3

ShakCentral Cold DOT Leveling: https://www.youtube.com/watch?v=dsyl3uclL6A

Transition when you have enough currency to afford the mandatory items (shouldn't be more than ~10c day 1) and have hit at least level 75. Don't worry about swapping immediately on reaching maps, cold DOT is a strong build through yellow maps with minimal investment. I swapped in early yellow maps and it felt smooth before and after. Recommended items should generally be your first upgrades.

What are your thoughts on creating this on a scion? Maybe adding in a Headhunter as well? Just need a fast mapper as I already have a bossing character.
