Info
- Inferno is Ember’s ability 4.
- Command a flaming comet to crash down in front of Ember, engulfing enemies with a fire that can spread through their ranks.
- 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.
Augment
Exothermic
Inferno Augment: Enemies killed while under the effect of Inferno have a 15% chance to drop an energy orb.

Max rank drain ~9; see rank table on the augment page.
Cast Changes
- Modifies Inferno with: Inferno Augment: Enemies killed while under the effect of Inferno have a 15% chance to drop an energy orb.
- Rank up the augment to unlock the full effect values.
- Costs a mod slot (and capacity) — only equip it when the change matters for your loop.
Worth the Slot?
- Worth it when the augment’s change is central to how you play Ember.
- Skip it if the base Inferno already does what you need and you’d rather keep the slot for survivability or strength.
Tips & Tricks
- Read the battlefield first — cast Inferno when it actually solves the room, not on cooldown habit.
- Pair Inferno with movement and energy economy so you’re not stranded after a big spend.
- On Steel Path, confirm whether Inferno still carries without strip, Viral, or a squad buff.
- If you never press 4, it’s the first Helminth candidate on Ember.

Mod Scaling
Strength
- Strength matters if Inferno scales effect power; otherwise dump it for other stats.
Duration
- Duration is low priority on Inferno unless an augment or lingering effect needs it.
Range
- Range is usually dumpable on Inferno unless you feel the hitbox is too tight.
Efficiency
- Inferno 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
| Mission | How to Use It |
|---|---|
| Steel Path Survival / Defense / Disruption | Test whether Inferno still clears or enables clear when enemies are dense and overlevelled. |
| Mobile Defense / Excavation | Use Inferno to control or delete the swarm on the objective, then reposition. |
| Exterminate / Capture Speed Runs | Cast Inferno only when it saves time — skip it on empty tiles. |
| Spy / Rescue / Quiet Routes | If Inferno is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe. |

Vs similar tools on other frames — Inferno is tuned for Ember’s loop — don’t judge it as a standalone subsume without the rest of the kit.
