Info

  • Gloom is Sevagoth’s ability 3.
  • Summon a radial pulse wave that ensnares and slows enemies, siphoning their lifeforce for the Death Well.
  • Use it with the rest of the kit — especially Reap, Sow — instead of casting it in isolation.
  • Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Tips & Tricks

  • Read the battlefield first — cast Gloom when it actually solves the room, not on cooldown habit.
  • Pair Gloom with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Gloom still carries without strip, Viral, or a squad buff.
  • If you never press 3, it’s the first Helminth candidate on Sevagoth.

Mod Scaling

Strength

Strength matters if Gloom scales effect power; otherwise dump it for other stats.

Duration

Duration is low priority on Gloom unless an augment or lingering effect needs it.

Range

Range is usually dumpable on Gloom unless you feel the hitbox is too tight.

Efficiency

Gloom costs energy each cast — Efficiency (or strong regen) keeps the loop comfortable on long missions.

Priority

Stack the stats that actually move this ability’s needle, then Efficiency for uptime.

Mission Use Cases

MissionHow to Use It
Steel Path Survival / Defense / DisruptionTest whether Gloom still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Gloom to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Gloom only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Gloom is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

Comparisons

  • VS

    Vs similar tools on other frames — Gloom is tuned for Sevagoth’s loop — don’t judge it as a standalone subsume without the rest of the kit.
