Info

  • Fire Blast is Ember’s ability 3.
  • Slam the ground to create a wave of incinerating plasma that knocks back enemies and strips their armor.
  • Use it with the rest of the kit — especially Fireball, Immolation — 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 Fire Blast with: Fire Blast Augment: Each enemy hit heals by 25 to 50 depending on current Immolation level.
  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 Ember.
  2. Skip it if the base Fire Blast already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

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

Mod Scaling

Strength

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

Duration

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

Range

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

Efficiency

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