Wings of the Dedicated are a vanity item for Diablo III. They are awarded to players who beat 24 Set Dungeons (excluding the Necromancer's) successfully (no matter with Mastery or not).
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.
Only the most dedicated heroes can wear these wings.
