Tool Upgrade Crafting guide
Short answer: The Feedback Resonator upgrade is for Angel Comb and Bloom Canker-style progression routes. Expect Conduit Crystal, Enameled Glass, and other advanced materials before you can build it.

Why Players Need It

If Angel Comb or infected-growth routes are not responding, this is the upgrade players usually check next.

When To Craft It

Do not craft Feedback Resonator just because the recipe is visible. Craft it when it unlocks a route, solves a current objective, or completes a material chain you have already checked. This is especially important in Early Access, where recipes and upgrade pacing can change after patches.

If Feedback Resonator depends on rare materials, keep those materials raw until the final target is clear. A processed ingredient can feel like progress while quietly reducing your options for the next vehicle, tool, or base upgrade.

Recipe Status

Crafted at: Modification Station. This is an advanced route tool. Check the Conduit Crystal and Creature Enamel pages before committing to the trip.

Related Resources

  • Conduit Crystal - For Conduit Crystal in Subnautica 2, plan around the Alien Ruins / Karakorum Power Plant route rather than a first-hour swim. Bring a prepared Tadpole and enough inventory space before farming.
  • Celestine - Celestine belongs with Alien Ruins progression. Treat it as a mid-game material and pair the route with Conduit Crystal only when your vehicle and storage are ready.
  • Creature Enamel - Creature Enamel belongs to the post-Tadpole Alien Ruins route and advanced crafting. Check this only after you are ready for creature-risk areas.

Crafting Mistakes To Avoid

  • Do not leave base for one ingredient before checking the entire recipe chain.
  • Do not spend rare resources if you cannot name the route or upgrade this item unlocks.
  • Do not trust old recipe screenshots after a patch without checking your current build.

Best Next Step

Open the linked resource pages first, then use the Crafting Planner to turn Feedback Resonator into a shopping list. If the route includes advanced materials, scout once before farming so you do not carry valuable stock into an unknown area.
