How to get the Feedback Resonator

Answer first

At a Modification Station, upgrade a Sonic Resonator after scanning two Feedback fragments. Against creatures, Feedback stuns instead of making them flee; it also clears the Alien Ruins Angel Comb's viral blooms. Search the Cicada Wreck Therapy Room and Metal Farm area; use the fragment landmarks in the steps below.

Fragment bearings and the third landmark can differ; use the named wreck/cave landmarks and confirm the station recipe before spending materials.

ToolsSonic Resonator, Modification Station
Depth / zoneKarakorum / Alien Ruins

Steps

  1. Own a working Sonic Resonator and can reach Alien Ruins / Karakorum depths (Tadpole + Depth Module).
  2. Scan two Feedback Resonator fragments from these reported locations: Cicada Wreck Therapy Room; the glowing cave near Metal Farm; or another fragment within Metal Farm. The listed bearings conflict, so use these landmarks instead.
  3. Bring your existing Sonic Resonator, 2 Enameled Glass, 2 Conduit Crystals, and 2 Strontium to a Modification Station. If the ingredient list differs in your build, follow the station UI before spending materials.

  4. Use the upgraded Resonator to destroy / clear the viral blooms around the second Angel Comb; its creature interaction is a stun, not a flee effect.
