Crimson Angelic Wings are a PlayStation 3-exclusive vanity item for Diablo III.
When used, they apply or remove "a display of heavenly power": glowing angelic wings.
When obtained, they can be added to the Wardrobe. Only one set of Wings can be used at a time. If equipped, they will be visible even in character selection screen.
So ancient are the angels of the High Heavens that many of their deepest secrets are lost, even to themselves. — Deckard Cain
