TL;DR: Kicking off Season 3 this year, League of Legends Classic brings players back to an earlier era, complete with the early Summoner’s Rift map, champion roster and kits, fan-favorite items, and more
On July 29 in Patch 26.15, League of Legends will release League of Legends Classic, a new gameplay experience that recreates the feel of early League while modernizing select systems for today's players.
While anchored in 2013’s Season 3, League Classic gameplay is a collection of greatest hits from across early League rather than an exact recreation of a single patch.
League Classic features old-school Runes and Masteries, items, Summoner Spells, a starting roster of 60 classic champions with many pre-rework kits, and a recreation of the Summoner's Rift map.
