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 - Eye of Hinekora (DO NOT VENERATE for the MANA - actually bad for the build, skip)

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

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

See "Early Maps" for prerequisites to swapping to this version.

Okay this is where all our abused mechanics come online. See the explanation above ^ for how this works. And see my initial league-launch video here for showcase and detailed explanation / demonstration: https://www.youtube.com/watch?v=awVaapidjwA

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

Gameplay

Early on in the end game, we are going to capitalize on cheap recoup for infinite stacks of Demon Form, essentially giving us infinite damage scaling in any single instance (perfect for day 1 end game mapping). Basically, you don't have to spend any $$$$, and the damage is always there.

When you start a map, spam Elemental Weakness until your recoup procs are fully regenerating your health/es globes. Then activate Demon Form, and keep it up for the rest of the map simply by spamming Spark and Spellslinger.

If any point you notice the Demon Form is causing your life to deplete, switch back to Elemental Weakness spam (you likely will have to do this as the boss is spawning).

The additional spells (Orb of Storms and Frost Bomb) are just there in case you want the infusions.

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

Itemization

The only requirement is Sacrosanctum. The "roll" does not really matter, you just need the last line for recoup of energy shield.

Blood of the Warrior flask can complement your recoup for 30% with almost no cost (and you don't use any flasks anyway)

Finally, Maligaro's Virtuosity is the play at the start (if they are cheap). If they are expensive you can just go rare gloves.

On your remaining gear, keep this in mind:

you just want to AVOID MANA (mana == bad), you actually want to eliminate it and INCREASE mana costs where possible.

you want recoup on your amulet, recoup as fire on your belt (from essence), and then recoup socket in your helmet

Ruby can roll +max fire res and +skill effect duration

Sapphire can roll recoup as life, crit chance, crit bonus, % max energy shield

Elsewhere, you want to stack resistances (max fire res required), stack life/strength, stack cast speed, and take your standard damage augmenting mods on the wand

Spellslinger wand (Dueling Wand base) is reasonably important if possible

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

Skill Gems

On Spark, grab Vilenta's Propulsion if you can but Projectile Acceleration III is fine as well. If you don't have Perfect Jeweler's Orb, then drop Unleash.

On Cast on Critical, 2x Comet is ideal but not required depending on how good your recoup is doing.

The Arbiter's Ignition on the Flame Wall is not required, just cool if you can get it.
