Upgraded Sonic Resonator that uses a bacterial feedback loop to shatter the armored (purple/pink) Bloom Cankers blocking the Alien Ruins Angel Comb chain. Required for Axum Vision Adaptation (251–450m tier).
Fires from longer range than the standard Resonator and only damages cankers while they're open. Time your shots to the canker's breathing cycle.
Where to Find
Scan Feedback Resonator blueprints in the late-game zone (Alien Ruins / Power Plant interior). Recipe upgrades the existing Sonic Resonator with bacterial-culture ingredients (Axum Bacterial Culture).
Notes
Carry both — the Feedback Resonator does not replace the Sonic Resonator for blue cankers; both tools exist in your loadout simultaneously.
