Arsenal

Playstyle

Hybrid caster / weapon-platform Uriel: keep the demon economy online, stack Brimstone charge while you shoot, and drop Brimstone when packs clump. Guns do consistent clear; Brimstone is the occasional room delete.

Passive abilities

Uriel’s three passives are the demons Catenach (left), Gulphagor (middle), and Vythelas (right). They stay active while alive — even if you Helminth over the matching ability. Tap Remedium (2) often to heal and revive them.

  • Catenach — Chains nearby enemies (slow scales with Strength; damage spreads). Kill chained targets to charge Brimstone. Mostly passive.
  • Gulphagor — Marks a target every ~4 s. Kill the mark for a large Health / Energy orb dump (Equilibrium can refill most of your bar). Also charges Brimstone.
  • Vythelas — Spawns minimap-marked runes from corpses. Pickup = fire-rate + Heat buff (Resupply-style). Fire-rate is Duration-gated; Heat can feel sticky. Rune pickups charge Brimstone.

Active abilities

  • 1 Infernalis — Keep it up. Jump / dodge to fly; parkour velocity and dodge speed make this much faster.
  • 2 Remedium — Tap on shield break, for cast i-frames, and often to heal/revive demons. Restore scales with max Health × Strength.
  • 3 Demonium — Spam for AoE vulnerability and the fastest Brimstone charge source.
  • 4 Brimstone — Huge persistent Heat zone; damage ramps with Strength. Cast when the room is grouped.

Mod breakdown

Duration

Helps Infernalis, Brimstone, Demonium’s fire-rate window, and demon timers. Aim ~155%+; 200%+ feels great via Duration shards and Arcane Concentration / Molt Efficiency. No effect on Remedium.

Efficiency

Negative Efficiency is fine if Gulphagor marks keep dying into Equilibrium orbs. Spam Demonium / Remedium while that loop lives.

Range

Matters for Catenach chains, Demonium explosions, and Brimstone coverage. Less important if you Helminth over Brimstone.

Strength

Primary stat across Vythelas buffs, Brimstone damage, Demonium vulnerability, Remedium restores, Gulphagor orbs, and Catenach slow. Archon Intensify procs often because 3 drains demons and 2 heals them.

Aura

Aura slot — Corrosive Projection is best-in-slot (armor reduction before Heat partial strip). Growing Power is the polarity-friendly alternative.

Exilus

Exilus slot — fully flexible.

Archon shards

At least two Casting Speed shards for Remedium / Demonium / Brimstone. Remaining three flex — a comfortable split is two Duration and one Parkour.

  • Parkour — Infernalis flight
  • Duration — Infernalis, Vythelas fire-rate window, Brimstone
  • Strength — most of the kit
  • Violet Equilibrium — can soften the Equilibrium mod in normal content; often not enough alone at level-cap spam

Helminth

Replace based on camping Brimstone vs mobile guns.

Brimstone focus — Helminth over 1

  • Bright Bonnet — energy + Strength for Demonium spam and Brimstone damage
  • Sickening Pulse — doubles Heat statuses in a large LoS AoE

Weapon focus — Helminth over 4

  • Thermal Sunder (Thermal Transfer) — +Heat that double-dips with Vythelas / Heat mods
  • Nourish — Viral + damage + energy comfort

Mission Usefulness

  • Steel Path Survival / Defense / Disruption

    Strong

    Long objectives let you stack Brimstone charge while guns clear between casts. Bring Infernalis and Demonium online early — drop Brimstone when packs clump or the squad already has strip.

  • Mobile Defense / Excavation

    Excellent

    Point-hold missions are this build’s home: Infernalis turns the objective into a killbox, and Brimstone deletes the next wave when it stacks on the point.

  • Exterminate / Capture Speed Runs

    Situational

    Usable if your guns are already strong, but the hybrid loop wants longer objectives than a three-minute Exterminate — skip Brimstone setup and just shoot.

  • Spy / Rescue / Nightmare

    Situational

    Only if you already know the tiles. Infernalis and Demonium are loud; this is not a stealth kit.

  • Open World / Bounties

    Strong

    Strong on packed bounty camps — Infernalis + guns for travel fights, Brimstone when the camp clumps. Operator / Archwing still covers empty stretches.

  • Long-Range Gunplay / Eidolon-Style Content

    Weak

    Brimstone and demon Heat want clustered packs, not long sightlines or Amp hunts. Bring a dedicated Eidolon / long-range kit instead.
