Cast Changes

  1. Modifies Hysteria with: Hysteria Augment: Damage increased by 350%, Critical Chance increased by 350%.
  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 Valkyr.
  2. Skip it if the base Hysteria already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

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

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

Duration

Extends how long Hysteria’s effect lasts.

Range

Range is usually dumpable on Hysteria unless you feel the hitbox is too tight.

Efficiency

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