Crystal Nucleus

The  is a location in the Crystal Hollows, mainly used to deposit collected Gemstone Crystals from expeditions. Players can travel to main areas of the map using each of four corners, including the Magma Fields directly below the platform. After the five required Crystals (Jade Crystal, Amber Crystal, Amethyst Crystal, Sapphire Crystal, and Topaz Crystal) are delivered to their respective statues, a treasure stash will appear opposite of the Topaz Crystal Statue. Treasure stashes are completely random, meaning each item listed isn't guaranteed to drop. Crystals are reclaimable as well to unlock more treasure stashes.
