Master Yi vs Rammus Matchup Summary

The Master Yi vs Rammus matchup is a decisive matchup in League of Legends ranked play. Based on 101 recent matches analyzed, Rammus wins with a 54.5% win rate compared to Master Yi's 45.5%, giving Rammus a 8.9 percentage point advantage. Rammus dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Master Yi players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential. The most significant statistical gap is in crowd control, where Rammus leads by 1.1s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Rammus has a strong advantage in this matchup. Master Yi players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Rammus overextending. Avoid prolonged trades and wait for team fights where positioning and coordination matter more. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Farming
1.1Master Yi
0.8Rammus
Master Yi and Rammus farm at nearly identical rates in this matchup, with only a 0.3 CS/min difference. Neither champion holds a meaningful farming advantage, so lane dominance will come from trading and jungle interaction rather than CS leads.
Damage
755Master Yi
525Rammus
Master Yi heavily out-damages Rammus by 230 DMG/min, dominating both short trades and all-in fights. Rammus should avoid extended combat and instead focus on burst trade patterns — short engages followed by immediate disengagement — to avoid letting Master Yi's sustained damage advantage take over.
Economy
13,546Master Yi
11,517Rammus
Master Yi generates a commanding 2,030 more gold per game than Rammus. This substantial economic advantage means Master Yi consistently reaches key item breakpoints earlier, creating a compounding lead that grows throughout the game. Rammus should focus on cost-effective item choices and avoid unnecessary deaths to prevent falling further behind.
Utility
0.3Master Yi
1.4Rammus
Rammus brings significantly more crowd control than Master Yi, with 1.1 more seconds of CC per minute. This large utility gap makes Rammus far more valuable in setting up jungle ganks, controlling objectives, and locking down targets in team fights. Master Yi should invest in tenacity and position carefully to avoid being chain-CC'd.
Sustain
1,185Master Yi
2,388Rammus
Rammus vastly out-sustains Master Yi, healing and mitigating 1,203 more damage per minute. This massive durability gap means Rammus can absorb significant punishment and remain in lane while Master Yi is forced to recall. Building grievous wounds early is essential for Master Yi, and focusing on burst trade patterns rather than sustained fights is critical.

Best Master Yi Build Against Rammus

Berserker's Greaves is the optimal boots choice against Rammus, providing the mobility and stats Master Yi needs most in this matchup. The top-performing core items for Master Yi against Rammus are Kraken Slayer, Death's Dance and Blade of The Ruined King.

Rammus dominates the early game (first 15 minutes) with a commanding 61.8% win rate — a 23.5 percentage point lead over Master Yi. This lopsided early game means Rammus can dictate the pace of the lane from level 1, controlling trades, wave state, and river priority.

Late game (25+ minutes) is equally balanced, with Rammus at 50.8% win rate — only 1.5 points ahead of Master Yi. Team fight execution and macro play determine the winner at this stage, not champion matchup advantage.

Rammus holds the advantage at every stage of the game, making this a consistently favorable matchup from lane through late game team fights. Master Yi players should look for outplays, team-dependent strategies, and picks rather than relying on scaling to win this matchup.
