Sonar

• Banshee emits a sound wave and reveals the location of every enemy within 20 / 25 / 30 / 35 meters. Tracked enemies will be visible on every player's mini-map, and each enemy will have a body part highlighted. These effects last for 10 / 15 / 20 / 30 seconds. Hitting an enemy in the highlighted area causes the inflicted damage to be multiplied by 200% / 300% / 400% / 500%.
  • Damage multiplier is affected by Ability Strength.
    • Damage can also be increased by body-part multipliers such as the head or unprotected body parts.
  • Duration is affected by Ability Duration.
  • Range is affected by Ability Range.
• Has a cast delay of about 0.8 seconds and a recast time of about 2.4 seconds.
• Recasting Sonar while it's still active will cause additional body parts to be highlighted. Highlighted areas can overlap, causing inflicted damage to be further amplified multiplicatively.
• Sonar does not highlight all enemies within its maximum area of effect immediately, instead the effect propagates outward from the caster's position, traveling at a fixed pace irrespective of Ability Range mods, similar to the mechanics of Nova's Molecular Prime.

Main article: Resonance

Resonance is a Warframe Augment Mod for Banshee's Sonar that triggers an additional Sonar pulse with a fraction of the original pulse's remaining duration if an enemy is killed in a highlighted weakspot.

• Can increase damage done by abilities if the glowing body part is the torso, since most abilities target the torso.
• This ability can help with ranking up new weapons, as the damage multiplier can increase a weapon's damage to a given area, thereby increasing ammo efficiency. Coupled with  Rifle Amp, this can greatly improve a weapon's effectiveness before it has enough room for much-needed mods.
• Because of its multiplicative nature, Sonar is arguably the most potential damage booster currently in the game. A fully modded Banshee combined with a fully modded Equinox can increase the damage multiplier to 18.95, so a single overlapping area will multiply the damage 359 times. For example: a single rifle shot of 5000 damage on a doubled-weakspot on an unarmored target would deal 1.8 million damage.
• Sonar's augment mod  Resonance helps greatly with Ability Efficiency, since it allows Sonars to be automatically cast every few seconds simply by dealing killing damage on weakpoints.
• Although the enemy reveal effect does not combine with  Enemy Radar or  Enemy Sense, it is stronger that either of them on their own.
• It seems the traveling speed of this ability depends on the distance to the target. The wave propagates at ~12 m/s for 24 meters, but at ~15 m/s for 48 meters and at ~16.5 m/s for 80 meters.
