Playstyle

Helminth over Exalted or Javelin — Blind/Howl CC while a weapon buff and guns clear. Chromatic Blade optional if you keep Exalted as panic.

Passive abilities

Umbra fights independently when you Operator out (unless Warrior's Rest). Radial Howl sheds Sentient resistances. Exalted Blade is still the damage engine — Chromatic Blade sets element from emissive color.

Active abilities

  • 1 Slash Dash — Dash through packs with Slash status and brief invulnerability. Surging Dash feeds combo.
  • 2 Radial Howl — Stun + strip Sentient resistances. Softens rooms before Exalted waves.
  • 3 Radial Javelin — Slash javelins / Furious Javelin melee buff. Common Wrathful Advance Helminth slot.
  • 4 Exalted Blade — Exalted sword + energy waves. Chromatic Blade is the modern damage augment.
  • Helminth over Radial Javelin or Exalted Blade (Roar / Nourish / Eclipse). Keep Blind/Howl.

Mission Usefulness

  • Steel Path Survival / Defense / Disruption

    Strong

    Blind / Howl CC + Helminth gun buff — Exalted optional.

  • Mobile Defense / Excavation

    Excellent

    Point-hold with Blind and gun clear.

  • Exterminate / Capture Speed Runs

    Excellent

    Skip Exalted swaps — shoot under Blind.

  • Spy / Rescue / Nightmare

    Situational

    Blind helps Spy-adjacent; not a stealth main.

  • Open World / Bounties

    Strong

    Guns cover travel.

  • Long-Range Gunplay / Eidolon-Style Content

    Situational

    Better than Exalted if your guns reach.
