Prioritize full clears and avoid early river fights to protect your tempo against Briar's high early pressure.
Focus on scaling through fast clears and use global (R) to impact fights without direct confrontation.
Avoid early isolated duels where Briar's mobility and CC can punish you hard.
Jungle Plan
Execute full clears toward safe camps and avoid early river fights unless lane priority guarantees support.
Contest Scuttle only when adjacent lanes can move first and collapse on Briar if she commits to a fight.
Use your superior clear speed and item timing to cycle camps quickly and reach key scaling breakpoints before contesting objectives like Dragon or Rift Herald.
Danger windows
Be cautious during your first clear when low health and vulnerable to Briar's early invade and stun (Q).
Avoid isolated river fights where Briar's high mobility and CC can trap you without lane assistance.
Respect forced smite fights early, as Briar's dueling and engage tools can outmatch you if unsupported.
Early game
Start with a full clear path that avoids predictable low-health river entries to reduce invade risk.
Delay contesting the first Scuttle unless nearby lanes have priority to support counter-ganks.
Track Briar's location and ping lanes early to prepare for her aggressive early invades and counter-ganks.
Power spikes
Level 6 unlocks (R) for global damage; use it to finish low-health enemies after skirmishes and force Briar to avoid extended fights.
First AP item spike increases clear speed and objective damage; leverage this to arrive early at objectives and pressure Briar's jungle.
Respect Briar's early level 3 power spike when she can fight hard; avoid fights before you have room to kite or lane support.
Win conditions
Convert your fast full clear tempo into early item spikes to pressure objectives and force Briar off camps.
Use vision and lane priority to avoid Briar's early invades and set up counter-ganks when she commits.
Leverage (R) after fights start or enemies drop low to influence cross-map skirmishes and secure objectives without direct presence.
