Use Fizz's early burst and mobility to disrupt Master Yi's farming rhythm and deny his free clear tempo.
Prioritize river control and scuttle vision to prevent Master Yi from safely farming and setting up resets.
Jungle Plan
Full clear quickly to hit level 3 and look for early invades on Master Yi's camps before he completes his first clear.
Contest river vision aggressively to control Scuttle and deny Master Yi safe access to objectives.
Use superior early dueling and burst to counter-jungle Master Yi when lanes have priority and he overextends farming.
Danger windows
Avoid isolated river fights before level 3 when Master Yi can sustain and counterattack with (W).
Be cautious contesting objectives if (R) is up and enemy lanes lack crowd control to prevent his reset chains.
Low-health clears after extended fights are risky; retreat promptly to avoid being caught by Master Yi's chase potential.
Early game
Start with a fast clear route that allows early level 3 power spike access to contest or invade Master Yi's jungle.
Fight for first Scuttle Crab only if nearby lanes have priority to back you up against Master Yi's low early pressure.
Avoid extended fights before level 3 when Fizz's combo is not unlocked and Master Yi's sustain can outlast you.
Power spikes
Level 3 unlocks Fizz's full engage combo with (Q), (W), and (E), enabling strong early dueling and invade potential; use this to pressure Master Yi's jungle camps.
Level 6 (R) provides a kill threat and pick potential; coordinate with lanes to force fights where you can burst Master Yi before he resets.
First completed AP assassin item increases your burst damage and objective control speed; leverage this to deny Master Yi's scaling and secure dragons or Herald.
Win conditions
Convert early jungle pressure and successful invades into dragon and Rift Herald control to snowball your lead.
Use superior early gank threat and burst to force lanes ahead, creating opportunities to counter-jungle Master Yi safely.
Deny Master Yi free farm and item spikes by maintaining vision control and punishing his pathing mistakes before he can clean up fights with resets.
