Cast Changes

  1. Modifies Decoy with: Decoy Augment: Decoy can be cast on enemies.
  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 Loki.
  2. Skip it if the base Decoy already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Decoy when it actually solves the room, not on cooldown habit.
  • Pair Decoy with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Decoy still carries without strip, Viral, or a squad buff.
  • If you never press 1, it’s the first Helminth candidate on Loki.

Mod Scaling

Strength

Improves Decoy’s damage or effect potency where Strength is listed on the ability.

Duration

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

Range

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

Efficiency

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