Guide Steps
Step 1: Locate the Old Habitat and scan fragments
The Old Habitat is approximately 370 meters north of your Lifepod. Swim north, keeping the seabed in view. The structure is a ruined habitat on the seafloor. Look for 2 Sonic Resonator fragments in and around the structure. Scan both to unlock the blueprint. This is the same area where you find Processor fragments.
Step 2: Gather crafting materials
The Sonic Resonator requires: 2 Titanium Ingot (6 Titanium via Processor), 2 Lead, 1 Basic Battery (2 Copper Ore + 1 Acidic Raion Pouch), 1 Wiring Kit (1 Silver + 1 Copper Wire). Lead is found in deeper cave systems and the Lead Zone biome. This is a significant material investment — prepare the component chain in advance.
Step 3: Craft the Sonic Resonator
Fabricator → Equipment → Sonic Resonator. Requires: 2 Titanium Ingot + 2 Lead + 1 Basic Battery + 1 Wiring Kit. It is a handheld tool that uses battery power. Each activation consumes a portion of the battery charge.
How to use the Sonic Resonator
Equip the Sonic Resonator, aim at the target, and activate. Primary uses: (1) Break large mineral deposits for bulk resource harvesting, (2) Clear Blighted Coral and Biofilm from structures and terrain, (3) Destroy Bloom Cankers — dangerous growths that damage nearby players. Does NOT affect Leviathan-class creatures.
Upgrade: Feedback Resonator
At the Modification Station, you can upgrade: 1 Sonic Resonator + 2 Enameled Glass + 2 Conduit Crystal + 2 Strontium → Feedback Resonator. The upgrade enhances resonator effectiveness and may add new functionality. Save your Sonic Resonator for this upgrade rather than crafting a second one.
