Elise is an early ganker and dive specialist who must leverage her very high early game pressure to snowball lanes before Udyr's mid-game tempo kicks in.
Prioritize early river control and invade Udyr pre-6 to punish his slower clear speed and capitalize on his vulnerability before he can cycle camps rapidly.
Jungle Plan
Use early three-camp clears to reach level 3 quickly and pressure lanes with ganks or dives before Udyr can respond.
Invade Udyr's jungle pre-reset when lanes have priority to deny his fast clear tempo and force him behind.
Prioritize dragon setups after successful ganks or invades to convert early leads into objectives and deny Udyr mid-game tempo.
Danger windows
Respect Udyr's early invade attempts post-full clear when he can leverage his movement speed and stun to force fights.
Avoid isolated river fights before level 6 where Udyr's stun and AoE damage can overwhelm Elise.
Be cautious contesting dragon or Rift Herald if Udyr's lanes lack priority or if you are low health after clears, as forced smite fights favor Udyr's sustain and dueling.
Early game
Start a three-camp clear into an early gank or invade to pressure Udyr before he completes his full clear.
Contest the first Scuttle only if nearby lanes have priority to collapse and support a fight.
Avoid extended fights if Udyr has priority on the river or lanes cannot assist, as his mobility and dueling are strong.
Power spikes
Elise's level 3 power spike enables lethal ganks and dives; use (E) cocoon and rappel aggressively to secure kills before Udyr can react.
Udyr's fast clear speed and empowered stance give him strong mid-game dueling; respect his level 4-6 window by avoiding isolated fights without lane support.
Elise's early burst damage and hard CC allow her to punish Udyr's slower early jungle pathing if timed correctly.
Win conditions
Convert early gank and invade success into lane leads that secure dragon and Rift Herald control.
Use superior early dueling and (E) cocoon to punish Udyr's jungle pathing and deny his farm and tempo.
Snowball lanes through dives and cross-map pressure before Udyr's mid-game power spikes to maintain objective control and force teamfights on your terms.
