Where it comes from

It hatches from a Geode egg in your island's hatchery (72 hours). The egg drops from monsters in The Carnival, The Vault, The Wilderness, The Deep Wild, The Depths of the Mountain, on about 0.05% of kills. Nestor the Egg Man in the Yard trades one for 60 abyss crystal + 2 glimmering geode. The Store sells it too. Two of them bred in your pen make a Greater one.

Wear, stow and name it in the Equipment tab. One at a time; the bonus stops the moment you stow it.
