Cast Changes

  1. Modifies Toxic Lash with: Toxic Lash Augment: Create 5m toxic clouds, dealing 300 Toxin Damage/s for 12s with every kill.
  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 Saryn.
  2. Skip it if the base Toxic Lash already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Toxic Lash when it actually solves the room, not on cooldown habit.
  • Pair Toxic Lash with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Toxic Lash still carries without strip, Viral, or a squad buff.
  • If you never press 3, it’s the first Helminth candidate on Saryn.

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