Amberwing is a Normal sword in Diablo III. It was added in patch 2.4.1.
It can only be used for Transmogrification, and drops from Erethon.
As it is a Normal item, it can be traded among players once acquired.
This sacred blade glimmers with the light of the High Heavens. Forged in harmony with the Lightsong, it represents the greatest potential of angelic weaponry.
