Cast Changes

  1. Modifies Regurgitate with: Regurgitate Augment: Regurgitated enemies bounce up to 3 times, creating gas clouds that last 8s and inflict nearby enemies with Gas Status Effect.
  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 Grendel.
  2. Skip it if the base Regurgitate already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

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

Mod Scaling

Strength

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

Duration

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

Range

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

Efficiency

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