ID: 34331 Eidolon Crystal Cannot trade. The Eidolons in the underground Eidolon temple grant rewards to brave challengers, with a trace of Divine Power slowly flowing within the purple Crystal. After collecting a certain amount, it seems possible to exchange them for something with the director of the Eidolon Research Institute.
