  • Take the skies and rain Balefire rockets down on the enemy.
  • Use it with the rest of the kit — especially Balefire, Pillage — 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 Aegis Storm with: Aegis Storm Augment: Balefire has an Alternate Fire during Aegis Storm.
  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 Hildryn.
  2. Skip it if the base Aegis Storm already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

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

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