The Three Demons

The three demons stay active as long as they live, even if you subsume their linked ability, so you cast 2 often to heal and revive them, which also triggers Archon Intensify continuously.

Gulphagor's marked kills are the energy engine: six health orbs and two energy orbs every four seconds, about 430 energy through Equilibrium.

Vythelas runes give a fire-rate buff and a heat buff coded like Cyte's resupply, which currently appears to last indefinitely once it sticks.

Demonium (3) applies an AoE damage vulnerability and charges Brimstone fastest.

Brimstone (4) covers a large area in guaranteed-heat damage that escalates over time.

1.

Keep Infernalis (1) up and jump-dodge to fly.

2.

Tap Remedium (2) on shield loss or when you need to be immortal, and often to heal demons.

Restoring 1150+ shield for the full 2.5s gate needs Archon Vitality's 1332 health and about 173% Strength.

3.

Tap Demonium (3) constantly for the vulnerability and Brimstone charge.

4.

Tap Brimstone (4) over the enemy area.

Duration wants 155% minimum, ideally 200%+, for Infernalis, Brimstone and the demon timers.

Efficiency is negative because Gulphagor refills the bar.

Range feeds Brimstone coverage and Catenach's chain; run negative Range only if you subsume Brimstone away.

Strength is the priority stat, scaling every demon effect, Brimstone, the vulnerability and the shield restore.

Blind Rage is the Strength, with Archon Intensify adding more through constant demon healing.

Primed Continuity holds Duration.

Overextended, Stretch set Brimstone's Range.

Primed Flow is the pool.

Equilibrium is the engine paired with Gulphagor.

Archon Vitality doubles heat procs, which is direct Brimstone and Vythelas-weapon scaling.

Corrosive Projection strips armor before heat does its partial strip.

The exilus is fully open: Power Drift, Cunning Drift, Firewalker, Primed Sure Footed.

Arcane Concentration over Hot Shot for a pure Brimstone build.

Pick one, based on focus.

- Over 1 for a camping Brimstone build: Bright Bonnet for energy and Strength, or Sickening Pulse to double all heat statuses in a large area.

- Over 4 for a mobile weapon platform: Thermal Sunder with Thermal Transfer for a heat add that double-dips Vythelas, or Nourish for viral and more energy.

Arcane Camisado for a fast 60% Strength stack from the demons, Arcane Hot Shot for 300% weapon crit chance stacked by his abilities.

Swap Hot Shot for Arcane Concentration on a Brimstone-only build, or Molt Augmented for unconditional Strength.

Madurai for Strength and cast speed fits the cast-heavy playstyle.

Vythelas's heat buff is the Cyte resupply family, so run weapons that want it: heat mods are mandatory (they double-dip the heat DoT), faction mods triple-dip.

Kuva Sobek with Acid Shells, Ocucor viral-heat, Detron.

Uriel can fire alt-fire weapons like Bubonico while flying.

Remedium's on-cast immortality and shield refill, backed by the 1332 health pool.

It fails if you cannot keep killing Gulphagor's marks and run dry, since Remedium then has no energy.

Gulphagor plus Equilibrium.

Everything depends on killing a marked target every four seconds.

The complexity is the cost: two subsystems (demons and actives) to track, and a weapon buff you have to physically chase.

Sparse content starves the energy engine.

A pure Brimstone camping build.

A pure weapon platform with Thermal Transfer.

Strong: huge energy economy, an area nuke, strong weapon scaling, immortal on demand, very mobile.

Weak: high tracking load, buff- chasing, energy engine needs consistent kills, several load-bearing interactions are unconfirmed bugs.

Players who want a busy, high-ceiling frame that nukes and platforms at once.
