Use Lillia's very high clear speed to outpace Diana's tempo and secure early jungle control.
Prioritize river control and objective setup using Lillia's high objective control and sleep CC to contest dragons and Rift Herald.
Manage early fights carefully to avoid Diana's burst combo and (R) all-in threat, focusing on tempo farming and smart pathing.
Jungle Plan
Execute full clears quickly and reset tempo around item spikes to maintain pressure and objective control.
Fight for river control and Scuttle when your lanes can move first, using (E) and (R) to set up grouped objective fights.
Track Diana's pathing to counter-gank her early ganks and punish when her (E) is on cooldown or (Q) misses.
Danger windows
Beware of Diana's level 3 burst combo timing when she can all-in with (Q)+(E) reset and shield.
Avoid isolated river fights before level 6 where Diana's mobility and burst can punish low-health clears.
Watch for forced smite fights around objectives where Diana's sustained damage and shield can outtrade you if you are low health.
Early game
Start with a full clear to maximize Lillia's fast AoE clear and gain tempo before Diana hits level 6.
Contest first Scuttle only if nearby lanes have priority to support river fights and avoid isolated skirmishes.
Avoid early invades into Diana's jungle unless you have vision and lane priority to punish her lower invade resistance.
Power spikes
At level 3, respect (Q)+(W)+(E) burst combo; avoid fights unless you have cooldown advantage or lane setup.
After your first full clear and item spike, use your superior clear speed and sleep CC to force objective fights and deny Diana's scaling.
At level 6, respect (R) ultimate as a high-threat engage tool; save your (R) to counter or initiate teamfights effectively.
Win conditions
Convert your faster clear speed and movement to secure early dragons and Rift Herald before Diana can contest.
Use (E) sleep setup combined with (R) in grouped fights to control objectives and enable your team to follow up.
Deny Diana's scaling by maintaining jungle tempo, counter-jungling when safe, and punishing her cooldowns and missed (Q) to snowball leads into objective control.
