Cantle of Earth
A fragment of earth used to unlock the Sylvan Chest.
— In-game description
The Cantle of Earth is one of four items required to unlock Dierdre's chest in the Hidden Garden jumping puzzle in Dierdre's Steps. It is obtained from the Cluster of Earth in the Hidden Garden, which is on the ground, beneath the cracked earth under the high tree in the center of the garden. You can climb any of the large shards of earth jutting from the ground and drop right on top of the cluster. It is surrounded by several veteran and normal Earth Elementals, that like to cripple, but they can all be run past fairly easily.
