Illaoi vs Udyr Matchup Summary

The Illaoi vs Udyr matchup is a decisive matchup in League of Legends ranked play. Based on 10 recent matches analyzed, Udyr wins with a 80.0% win rate compared to Illaoi's 20.0%, giving Udyr a 60.0 percentage point advantage. Game phase dynamics play a critical role here: Illaoi controls the early laning stage, but Udyr outscales as the game goes longer. The matchup shifts dramatically depending on game length — Illaoi needs to press advantages before Udyr reaches their power spikes, while Udyr should focus on safe farming and hitting key item breakpoints. The most significant statistical gap is in crowd control, where Udyr leads by 0.9s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Udyr has a strong advantage in this matchup. Illaoi players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Udyr 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.

1,046Illaoi
768Udyr

Sustain
