The jungle race — the windows in Karthus's plan

Read from Karthus's seat: the race windows this plan plays for against Udyr.

StageReadWhy
Level 1 ClearDanger — Avoid UdyrUdyr out-classes you at the first buff — Blazing Stampede's stun plus Wingborne Storm shred wins any straight fight, and Blazing Stampede's stun-lock into awakened stance damage runs you down in a straight line. Skip the level-1 crossing, full-clear away from them, and trade map pressure instead of health.
Level 2 SkirmishDanger — Avoid UdyrDo not be seen on the second camp: Blazing Stampede's stun-lock into awakened stance damage runs you down in a straight line. On top of that, Blazing Stampede's stun plus Wingborne Storm shred wins any straight fight, so they get there first. Pre-position toward your tier-two side and dodge the first stun engage. Refuse the level-2 skirmish and farm the opposite quadrant until your spike lands.
Level 3 RouteDanger — Avoid UdyrHard no-contest for Karthus at level 3: four stance points are online and their awakened trades hit their hardest window, and Blazing Stampede's stun-lock into awakened stance damage runs you down in a straight line. Pre-position toward your tier-two side and dodge the first stun engage. Path opposite, ward your entrances, and let the clock carry you to your own spike.
Levels 4-5 MacroDanger — Avoid UdyrThis is a no-contest window: he farms 4-5 at speed and takes any fight near a wall, since Blazing Stampede needs only a straight line, and you have nothing that answers it. Full-clear the far side and let the objective timers carry you.
Level 6 BreakpointRespect Udyr's RUdyr wins the breakpoint outright — awakened stance rotations on four points hit harder than most actual ultimates, and awakened Blazing Stampede chains stuns faster than your cooldowns recover. Break the chase with walls — his power is point-blank and he cannot force the fight, then trade objectives cross-map until your items land.
First Item SpikeLiandry's SpikeLiandry's plus your farm lead makes Defile standoffs unwinnable for Udyr 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. Udyr's first item is where the awakened stance rotations stop being a heavy trade and start being a kill.
2+ Items ScalingKarthus Favoured — Wins LateFrom two items you out-scale Udyr. He is an awakened-stance brawler with sustain, damage and a stun on a short timer, but none of that beats your full build in a straight fight.

How to beat Udyr as Karthus: the first clear and pathing

Start blue-side regardless of map side preference arguments — your mana economy is your clear speed. Track Udyr's entry only to know which half of your farm to bank first; you race nobody, you out-pace everybody. Udyr clears extremely fast with stance swaps and shields himself through it, so he is rarely below full health.
