Rotorswell

Gyre’s mechanisms spin at incredible speeds, generating an Electric Field that shocks nearby enemies. When Gyre gets a critical hit, a large electrical discharge will chain from the enemy that was hit to nearby enemies.

Info

  • Rotorswell is Gyre’s ability 4.
  • Gyre’s mechanisms spin at incredible speeds, generating an Electric Field that shocks nearby enemies.
  • Use it with the rest of the kit — especially Arcsphere, Coil Horizon — instead of casting it in isolation.
  • Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Cast Changes

  1. Modifies Rotorswell with: Rotorswell Augment: 35% of damage received is redirected toward the instigator as Electricity Damage.
  2. Rank up the augment to unlock the full effect values.
  3. Costs a mod slot (and capacity) — only equip it when the change matters for your loop.

Worth the Slot?

  1. Worth it when the augment’s change is central to how you play Gyre.
  2. Skip it if the base Rotorswell already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Rotorswell when it actually solves the room, not on cooldown habit.
  • Pair Rotorswell with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Rotorswell still carries without strip, Viral, or a squad buff.
  • If you never press 4, it’s the first Helminth candidate on Gyre.

Mod Scaling

Strength

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

Duration

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

Range

Increases Rotorswell’s reach, radius, or targeting distance.

Efficiency

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