About RuneDiff

RuneDiff gives League of Legends players builds, runes, counters and team comps for every champion and role, free and without an account. Everything is updated for patch 26.20.

Where the data comes from

Champion, item, rune and ability data comes from Riot Games' public Data Dragon service. Builds combine match statistics with hand-written guidance.
