The Rammus versus Master Yi matchup in the jungle is favorable with proper positioning. Use your statistical advantage and prevent the opponent from realizing their potential.
The magic damage that Rammus deals remains relevant in the late game. Look for opportunities to initiate or counter-initiate. Master Yi has mixed damage, be careful as it may be harder to defend if the opponent gets ahead or plays aggressively.
Consider the farming superiority demonstrated by Master Yi, ranking 33rd (versus 51st for Rammus) in farming efficiency among champions in this role. This means the opponent can build gold advantages more quickly. Meanwhile, their lower KDA (2.1 versus 3.2) suggests they are less effective in team fights.
Despite the statistical advantage in the matchup, overconfidence can be the main mistake. It is important for the Rammus player to maintain constant pressure on Master Yi, not allowing the opponent to safely scale up, and actively use the advantage gained to help their team.
