Info

Amp is Octavia’s ability 4.
Draws power from the decibel level of sound in the area and uses it to amplify a damage buff for Octavia and her allies.
Use it with the rest of the kit — especially Mallet, Resonator — instead of casting it in isolation.
Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Tips & Tricks

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

Mod Scaling

Strength: Improves Amp’s damage or effect potency where Strength is listed on the ability.
Duration: Duration is low priority on Amp unless an augment or lingering effect needs it.
Range: Increases Amp’s reach, radius, or targeting distance.
Efficiency: Amp 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 Amp still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / Excavation	Use Amp to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed Runs	Cast Amp only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet Routes	If Amp 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 — Amp is tuned for Octavia’s loop — don’t judge it as a standalone subsume without the rest of the kit.
