To unlock the shrine, you must drain the water surrounding it. Go down the side of the cliff beside the shrine, where you will find a Like Like and a protrusion of stone. In the ceiling above the protrusion, there are breakable rocks. Destroy the rocks to drain the water.
A Retraced Path
- Hit the stone at the front to retract the slope.
- Walk to the right side of the room and use Ascend to access the Treasure Chest containing a Large Zonai Charge.
- Hit the stone again and wait for a sphere to fall out.
- Retract the slope again by hitting the stone once again.
- Use Recall on the sphere to send it back to the start of its path, which will insert it into the hole.
- While still in Recall, pass through the gate to the altar to get your reward.
