Eternum Nocturne

Released in December 2012, Eternum Nocturne belongs to the Legendary tier, which gave it a more elaborate look and theme in keeping with the premium Eternum line. Legendary skins in League generally go further in their changes than Epic or Standard releases do.

You can still buy it outright for 1820 RP. There are no chromas attached, so the skin rests entirely on its single Legendary design.
