Baron Buff

Baron Buff is a League of Legends coaching and tracking brand that helps players make informed decisions before, during, and after each match. Its tools combine match data, machine learning, statistical models, and insights from professional coaching sessions to provide practical, game-specific guidance.

During champion select, Baron Buff analyzes team compositions, counters, synergies, and the champions a player prefers to recommend picks, bans, runes, summoner spells, and builds. Before and during games, it offers matchup advice, jungle-pressure insights, win conditions, phase-specific priorities, and live item recommendations. Players can view coaching guidance in a browser or use the optional, customizable Windows overlay.

Baron Buff also provides post-game reviews that connect feedback to evidence from a match and suggest areas for improvement. Its Tracker organizes match history and progress, including rank and LP history from recorded ranked games, with comparisons to players at a similar rank. The standalone Windows app is designed to use few system resources and does not require Overwolf.
