Info

  • Wil-O-Wisp is Wisp’s ability 2.
  • Cast forward a spectral image of Wisp to confuse and distract enemies.
  • Use it with the rest of the kit — especially Reservoirs, Breach Surge — 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 Wil-O-Wisp when it actually solves the room, not on cooldown habit.
  • Pair Wil-O-Wisp with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Wil-O-Wisp still carries without strip, Viral, or a squad buff.
  • If you never press 2, it’s the first Helminth candidate on Wisp.

Mod Scaling

Strength

Strength matters if Wil-O-Wisp scales effect power; otherwise dump it for other stats.

Duration

Duration is low priority on Wil-O-Wisp unless an augment or lingering effect needs it.

Range

Range is usually dumpable on Wil-O-Wisp unless you feel the hitbox is too tight.

Efficiency

Wil-O-Wisp 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 Wil-O-Wisp still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Wil-O-Wisp to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Wil-O-Wisp only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Wil-O-Wisp 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 — Wil-O-Wisp is tuned for Wisp’s loop — don’t judge it as a standalone subsume without the rest of the kit.
