How to win the jungle race as Karthus against Master Yi · Matchup data reviewed on patch 26.15
Read from Karthus's seat: the race windows this plan plays for against Master Yi.
| Stage | Read | Why |
|---|---|---|
| Level 1 Clear | Respect Master Yi | At level 1 this window belongs to Master Yi, not Karthus: Alpha Strike untargetability dodges your key spell and Wuju true damage wins long trades. Hold your main ability until Alpha ends, and force fights before his items arrive. Skip the level-1 crossing and bank tempo on the opposite side of the map. |
| Level 2 Skirmish | Respect Master Yi | Alpha Strike untargetability dodges your key spell and Wuju true damage wins long trades — Karthus has no answer to that at level 2. Hold your main ability until Alpha ends, and force fights before his items arrive, and answer their pressure cross-map instead of contesting it head-on. |
| Level 3 Route | Respect Master Yi | The window at the opening scuttle is theirs: Alpha Strike untargetability dodges your key spell and Wuju true damage wins long trades. Hold your main ability until Alpha ends, and force fights before his items arrive. Give up the level-3 river fight and give up the first scuttle rather than the kill. |
| Levels 4-5 Macro | Respect Master Yi — Path Opposite | Levels 4-5 still belong to Master Yi in a straight fight — farm the opposite side, answer their ganks cross-map, and wait for your spike. |
| Level 6 Breakpoint | Respect Yi's R | Highlander makes him un-kitable and every takedown resets the chase — Karthus loses the straight post-6 duel. Hard CC is the only answer — chain stuns or do not take the post-6 fight, and shift your pressure to the side of the map Highlander is not on. |
| First Item Spike | Liandry's Spike | Liandry's plus your farm lead makes Defile standoffs unwinnable for Master Yi and your Requiem chunks brutal. You now solo Dragons early with W-E pit control. Force the enemy to fight inside your aura at every objective — or concede them on the clock. Master Yi's first item is the start of the curve rather than a spike — his real jump is the second and third. |
| 2+ Items Scaling | Respect Master Yi Late — End Early | Master Yi out-stats you from two items on — stop taking straight 1v1s, close through objectives and picks, and keep the game on a clock. |
Start blue-side regardless of map side preference arguments — your mana economy is your clear speed. Track Master Yi's entry only to know which half of your farm to bank first; you race nobody, you out-pace everybody. Master Yi clears very fast with Alpha Strike and Wuju Style, and he will be a level ahead if nobody interrupts him.
