Shyvana should leverage her superior clear speed to outpace Karthus and control early jungle tempo.
Focus on securing dragon priority and scaling into powerful dragon-form fights rather than forcing early duels.
Avoid early river skirmishes without lane priority as Karthus's poke and global damage can punish isolated fights.
Jungle Plan
Prioritize fast camp cycling and full clears to maintain tempo and deny Karthus free farm.
Use lane priority from bot and mid to set up safe dragon control and vision around river.
Track Karthus's pathing to counter-gank his early moves and punish his weak early dueling and invade resistance.
Danger windows
Early game river fights are dangerous without lane priority due to Karthus's poke and slow from (W).
Avoid forced smite fights before your dragon-form and item spikes to prevent losing tempo.
Be cautious when clearing camps low on health as Karthus can punish with repeated (Q) and global damage (R).
Early game
Start with a full clear to hit dragon-form and item power spikes faster than Karthus.
Contest first Scuttle only when nearby lanes have priority to avoid risky early fights.
Avoid invading early unless you have lane assistance, as Karthus is vulnerable to early disruption but can punish isolated invades.
Power spikes
Level 6 unlocks Shyvana's dragon-form engage, enabling stronger skirmishes and objective control; use this to force fights when Karthus lacks (R) impact.
First major item spike enhances Shyvana's clear and fight potential, allowing earlier objective pressure before Karthus completes his AP item.
Respect Karthus's level 6 (R) global damage which can finish low-health enemies; avoid extended low-health fights across the map.
Win conditions
Convert faster clears into dragon control by coordinating with priority lanes to secure vision and force Karthus off objectives.
Use dragon-form power spikes to win mid-game fights and deny Karthus scaling through objective pressure.
Counter-gank and invade after tracking Karthus's pathing to disrupt his farming and delay his item spikes.
