Just got a fey crystal, anyone know what it is used for?
Edit: Fey crystals are rare drops. They become unlocked as you complete the Tabernum Research quests.
Shard 1 - they drop from wells and ponds
Shard 2 - they drop from monsters
Shard 3 - they drop from crops
Sir Pigglesworth has also been known to drop them.
They are not currently used for anything but will have a use in the future.
