Jonsau Shrine — Buoyancy

Location: Faron, Lake Hylia area Ability Required: Ultrahand Difficulty: Easy — buoyancy and floating object puzzle

Overview

Jonsau Shrine explores buoyancy mechanics — objects in water behave according to their density. Wood floats, stone sinks, metal sinks. You'll use this knowledge to create floating platforms and raise submerged objects by attaching buoyant materials to them.

Preparation

• No combat
• No special gear
• Takes 4–6 minutes

Walkthrough

Room 1 — Float the Platform

1. A stone platform sits submerged at the bottom of a water pool. The exit ledge is above the water.
2. Three wooden logs are available. Use Ultrahand to attach the logs to the underside of the stone platform — the wood's buoyancy lifts the stone.
3. As more logs are attached, the stone platform rises. With 3 logs, it floats at the water surface.
4. Board the floating platform and walk to the exit ledge.

Room 2 — Raise the Key

1. A key (needed for a locked gate) is sunk at the bottom of a deep pool. It's too heavy to lift normally.
2. Attach 2 logs to the key with Ultrahand — the combined wood-key object floats to the surface.
3. Grab the key (now at the surface), open the gate, proceed.

Room 3 — Variable Depth

1. The altar is behind a gate requiring a pressure plate to be held down underwater.
2. A heavy stone block needs to be placed on the underwater pressure plate — but it needs to be held down by enough weight to resist floating back up.
3. Attach a metal anchor to the stone block before submerging it — the metal weight ensures the stone stays on the plate.

Tips

• Buoyancy math: 1 log barely floats a stone block. 3 logs comfortably float it at surface level. For heavy objects (stone + metal anchor), you may need more buoyant material attached.
• Log attachment position: Attach logs to the bottom or sides of heavy objects — logs on top don't contribute buoyancy effectively.
• Key retrieval Room 2: Don't over-attach logs to the key. 2 logs = key floats. More logs = key floats faster but harder to control placement.
• Room 3 anchor: The metal anchor in Room 3 is the only way to hold the stone on the underwater plate. Without it, water pressure "pushes" the stone back up off the plate.
• Faron's water: Lake Hylia area water is safe to swim in. No drowning mechanic applies in this shrine — swim freely between sections.
