Sea Eyes

These bluish opaline gems are flat disks about the size of a human eye. They are created by the divinations of water fay such as mer, nixies, nagas, sprites and nereids that use water elemental magics. Their divinations shape the elemental plane and inadvertently create the sea eye crystals. They are most commonly found in places close to the Elemental Plane of Water, such as the Sprites Realm, the Fountainhead, the Abyss or the Nexus of Water.
Sea Eyes can be used for 1 level of Divination magic per Sea Eye utilized up to 4th level. Sea Eyes are devoid of their own magic so to empower and gain a level of Divination the user must sacrifice a personal spell into the Sea Eye.
