Build Overview

======================================================

WELCOME

This is a comprehensive Level 1 to Uber Endgame min/max variant guide.

IF you are new or casual, I take special care to make the progression VERY clear and obvious.

IF you are a veteran, the endgame version of this archetype is going to push the limits, and you will enjoy how it works.

I respond to all relevant comments on YT and am active in our Discord. We also have some other GOATed Gurus in the Discord @arq @cur$e and @i9314. Give your thanks to these goats.

Please post questions in the Spark channel in Discord. TYTY GL! <3

Explanation of Primary End Game Mechanic

The main thing GGG targeted in caster nerfs for 0.5 is RESOURCE REPLENISHMENT. We caster bros have rushed to find more hacks at this, and GGG continues to slough off new findings. One methodology that should not get nerfed (because it is so core to Infernalist) is the node Pyromantic Pact.

Pyro Pact removes our mana (completely), and gives us infinite resources (literally). It also inverts how resources get used (rather than going from full to empty, they go from empty to full and reset). When your "mana" (called Infernal Flame) gets full, you take ALL OF YOUR HEALTH and ES as damage to yourself (sounds bad, right?).

Believe it or not, this build inverts this downside into an upside with recoup. We stack life/energy shield recoup, slot in Sacrosanctum, and become nearly invincible while also completely removing the downside from Pyromantic Pact and giving ourselves essentially infinite mana.

The mechanic is so powerful, and we invert the downside so dramatically, that we actually WANT to take the damage downside MORE frequently. So anywhere we can actually reduce our mana pool and increase the cost of spells turns into a GOOD thing.

Also, because our recoup becomes routinely 4000+ life/ES replenishment per second, in the early/cheaper endgame variant we can stack infinite Demon Form + Demonic Possession, giving us limitless spell damage over the course of an instance. In the later/$$$$ endgame variant, we drop Demon Form and stack crit with Grinning Immolation and a set of low life techs related to Coward's Legacy, Pain Attunement, and Execute III. The final form pulls off the traditional delete-any-boss-in-seconds mode without any pre-conditions.

Quest Bonuses:

A2 - Charm Duration (Valley of Titans)

A3 - Ailment Threshold (Venom Crypts)

A4 - 3x Resists (Halls of the Dead)

A4 - Life Recovery from Flasks (Abandoned Prison)

A4 - 30% Armour, Evasion, ES (The New Thing: Shark Fin)

I2 - Resists (Qimah)

Strengths and Weaknesses

End game archetype relies on complex interactions that are difficult to understand
If you are not familiar with Spark skill rotation/playstyle in campaign and early mapping, you will struggle

VARIANT: Early Mapping (T1-T9)

-------------------------------------------------------------------------

I've added this variant by demand to assist with the transition to the end game archetype playstyle / interaction.

The key for scaling in maps is:

1 - Don't swap too early. Keep your Demon Form capped at 10-stack until you have 100% recoup, 6-link Spark or Frostbolt, and lots of cast speed. Yours rares need to be aligned with the archetype (see video). Ideally level 83 for skill tree requirements... you also MUST HAVE high level gems (19 level base and scaled gem levels on gear).

2 - Continue to do your rotation very carefully. It is Frost Bomb / Orb of Storms / Sigil of Power / Flame Wall / Spark. Stay in the Sigil, and repeat. Maximize the Cold-Infused sparks (double damage), the stacks of Unleash on spark, and the 30% more damage buff from Flame Wall on Spark.

3 - Read Cast on Critical gem. JUST your Crit Chance is not all that is needed to proc Comet. You need good damage, and generally weakening the boss is going to make them more susceptible to your % of energy gain from the gem interaction.

4 - Take Summon Infernal Hound and The Bringer of Rain on Ascendancy while you stack $$$ for the swap.

5 - Start to slowly improve all your rare gear (you want max life, strength, NO MANA, energy shield, and resists ... on rings you want some caster modifiers on there [see the breach tree]).

-------------------------------------------------------------------------

Itemization

1 --> Wait on a Dueling Wand until you can get a good one.

2 --> If you are poor, craft a giga 2-handed staff. (Buy a 6-stat REALLY strong one for 1-2 Exalt [Damage as Extra %, Spell Damage, Cast Speed, Lightning Damage, etc. ... Slam it with a Perfect Essence of Sorcery. Don't slam the Cast Speed and you are good to go)

3 --> Maligaro's Virtuosity and Heroic Tragedy are too expensive if you are poor, so invest your money elsewhere during this phase.

-------------------------------------------------------------------------

Skill Gems

Here's the key updates:

Make sure to get Vilenta's Propulsion for Spark
Quality up your Sigil of Power on the Chiming Staff for more AOE, and socket the supports
Put Fortress II in your Flame Wall; stand in the center of it, and ALL Spark Proj will be buffed (use Lightning Infusion on the wall for double-buff)
Add Doedre's Undoing to Elemental Weakness for persistent ground curse. This makes it more usable in regular situations (beefy rares, and of course bosses)
Note that Siphon Elements is not really that important. If you are starved for spirit, let it go.
Quality on Cast on Critical lowers the spirit cost.
Summon Infernal Hound is a nice defensive bonus. Socket it up.
