Guide Steps
Step 1: Unlock the blueprint
Scan Sonic Resonator fragments found near medium-to-large wrecks in the Kelp Forest and Grassy Plateau (30–60m depth). You need 2–3 fragments. Fragments look like small dish-shaped devices. Check wreck interiors and surrounding debris fields.
Step 2: Gather crafting materials
The Sonic Resonator requires: 1 computer chip (1 gold + 2 table coral + 1 copper), 1 battery (1 copper + 1 acid mushroom), 1 titanium. The computer chip is the most complex component — you'll need gold from sandstone outcrops and table coral from coral tubes.
Step 3: Craft the Sonic Resonator
Fabricator → Equipment → Sonic Resonator. Materials: 1 computer chip + 1 battery + 1 titanium. It's a handheld tool and uses battery power — each use drains a portion of the battery charge. Carry a spare battery when using it actively.
Step 4: How to use it
Equip the Sonic Resonator, aim at a creature, and activate. The sound wave will cause most medium-sized predators to flee or become distracted for several seconds. Use this window to swim past, collect resources, or reposition. It doesn't work on leviathan-class creatures.
Usage strategy
The Sonic Resonator is a tool of opportunity, not a weapon. Use it to create brief safe windows for resource collection in predator-heavy areas. It's particularly useful in the Kelp Forest (stalkers) and Grassy Plateau (sand sharks). Don't rely on it as your only defense — always have an escape route planned.
