Bathaius' Wing

A large humanoid-sized statue of a Winged Creature. The statue depicts an Angel with wings curled around it in a protective gesture, hands cupping what appears to be an orb. This piece is called Bathaius' Wing, and it is the representation of one of the Children of the Cosmos. This artifact is one of a kind, and will chose its Bearer. Once the Bearer holds the Artifact, it seemingly melts into their body, unable to be removed unless the Bearer is Killed. The Bearer's Soul cannot be brought back to Life unless they have the Artifact.

Once "attuned", no matter their Level, the Bearer is granted the ability to speak Celestial, and is Resistant to Radiant Damage.
