Riot Graves

Released in August 2012 as part of the Riot skin line, Riot Graves honors the developer itself. It is now stored in the Legacy vault and appears only during the occasional special-event sales, not in the regular rotation. Among the champion’s older cosmetics, it holds Standard rarity.

The 975 RP cost belongs to that earlier period. To get it, you’ll need to catch one of the rare times Legacy skins come back for a short stretch, since it can’t be bought on demand.
