Prioritize efficient full clears to hit level 6 on tempo and avoid early river fights without lane priority.
Use your strong mid-game teamfight presence and objective control to contest dragons and Rift Herald after level 6.
Respect Fiddlesticks's post-6 ultimate threat and avoid early direct invades before you have lane priority or vision control.
Jungle Plan
Focus on fast clears and path camps toward objectives after level 6 to leverage your ultimate in fights.
Fight for Scuttle Crab and river control only when your lanes can assist or you have vision advantage.
Track Fiddlesticks's pathing to counter-gank his post-6 ganks and punish his low early invade resistance by invading after level 3 if lanes have priority.
Danger windows
Avoid isolated river fights before level 6 when Fiddlesticks can out-clear and punish you.
Be cautious contesting objectives without vision control, as Fiddlesticks's (R) can turn fights instantly.
Watch for forced smite fights or low-health clears where you can be countered or collapsed on by enemy laners.
Early game
Start with a full clear toward a safe reset to hit level 6 quickly and avoid early skirmishes.
Only contest first Scuttle Crab if nearby lanes have priority to help secure it safely.
Avoid fighting Fiddlesticks early since he clears faster and can punish overextensions before level 6.
Power spikes
At level 3, use your (Q)+(W)+(E) burst combo to punish Fiddlesticks when he oversteps or lacks vision.
Level 6 unlocks your (R), enabling strong all-ins and objective fights; use this to force plays or reset fights.
After your first completed AP skirmish item, increase pressure on camps and objectives to deny Fiddlesticks scaling and force fights on your terms.
Win conditions
Convert your level 6 ultimate and burst combo into objective control by forcing fights around dragons and Rift Herald.
Use your superior clear speed and mobility to invade and deny Fiddlesticks camps when lanes have priority.
Coordinate with lanes to counter-gank Fiddlesticks's post-6 ganks and snowball your lead through picks and skirmishes.
