Legend of the Skyfish 2: How to Get the Aquamarine Key

To get the Aquamarine Key in Legend of the Skyfish 2, reach the central dais in the island labyrinth, solve the switch puzzles to lower the protective gates, and open the ornate chest. Once you collect the key, take the newly opened shortcut gate to exit the area and unlock the sealed maritime gateway.

Navigating Gaps and Water Hazards

The path to the key requires using your fishing pole as a grappling hook to traverse disconnected platforms surrounded by water. Falling into the water costs health and resets your position.

Target valid grapple points: Hook onto wooden stumps, stone obelisks, and metal mooring posts to pull yourself across open water.
Bypass walkway hazards: Rotating blades and spiked urchin traps patrol narrow land routes. Grapple directly to distant anchor points across channels rather than attempting to slip past them on foot.
Time moving rafts: Aim at moving platforms as they drift toward you. Cast your line just as the raft enters your rod's maximum range so you land in the middle of the platform.

Solving Switch and Gate Puzzles

Reaching the key chest requires lowering several iron gates. Use your fishing line to interact with switches located on distant platforms.

Puzzle Element	Function	Required Action
Weighted Floor Plate	Lowers nearby iron gates while weighed down	Use your hook to pull stone statues or pushable blocks onto the plate to hold the gate open.
Remote Lever Post	Opens short-duration gates across water	Cast your line across the water to strike the switch, then immediately grapple through the opened gate.
Timed Node	Lowers barriers for a few seconds	Activate the switch, then dash along your planned path immediately before the timer expires.

If a gate remains closed, inspect the floor lines to trace the mechanism to its trigger. Unsolved triggers are often located on separate islets that require long-range hook targeting.

Combating Ranged Turrets and Guards

Engaging enemies directly on narrow paths increases the risk of falling into the water. Prioritize crowd control and positioning:

Eliminate ranged attackers first: Stationary totems and aquatic spitters fire projectiles across channels. Use your fishing pole to pull small ranged enemies directly to you, interrupting their attack animations.
Finish pulled targets: Strike reeled-in enemies with standard melee swings before they recover from the pull.
Stun heavy enemies: Armored targets cannot be reeled in across gaps. Hit them with your hook to stun them briefly, close the distance, and attack from their flanks.

Claiming the Key and Next Steps

After solving the final multi-switch puzzle and defeating the remaining guards, walk up to the ornate chest on the central dais and open it to receive the Aquamarine Key.

Do not backtrack through the solved puzzle rooms. Look for the exit gate that lowers near the chest dais. Take this shortcut path back to the entrance, then proceed to the locked maritime gate to use the Aquamarine Key.
