Use Briar's high clear speed and dueling to pressure Diana early but avoid overcommitting to invades without lane priority support.
Focus on controlling river scuttle and objective vision to set up skirmishes where Briar's sticky engage and crowd control can shine.
This is a snowball jungle matchup where Briar must leverage early tempo and protected skirmishes to deny Diana scaling and objective control.
Jungle Plan
Prioritize pathing toward volatile lanes with strong lane priority to enable Briar's high gank threat using (Q) and (R) for sticky engages.
Use tempo advantage from fast clears to invade Diana's jungle camps only when exit paths are clear and lane priority protects from collapse.
Control river vision and coordinate with lanes to contest dragon and Rift Herald, forcing Diana into teamfights where Briar can clean up with sustained damage.
Danger windows
Beware early invade attempts around level 3 when Diana can punish overextensions if Briar commits without lane priority or vision.
Respect isolated river fights before level 6 where Diana's burst and mobility can overwhelm Briar without team support.
Avoid forced smite fights or objective contests when low on health or without lane priority, as Diana can kite and disengage effectively.
Early game
Start with a healthy clear path that keeps Briar at full HP to maintain tempo and look for early river Scuttle control.
Contest first Scuttle only if nearby lanes have priority to support counterganks against Diana's medium invade resistance.
Avoid early isolated fights before level 6 where Diana's burst combo and mobility can punish failed commits.
Power spikes
Respect Diana's level 3 power spike when she unlocks (Q)-(W)-(E) burst combo; avoid giving her clean setups for all-ins.
Track Diana's level 6 (R) availability and hold key defensive tools to survive her all-in threat or punish after her ultimate is used.
Use Briar's high dueling and mobility spikes post-level 6 to win extended fights and snowball through objective control and cleanup skirmishes.
Win conditions
Convert Briar's tempo and healthy clears into aggressive counter-jungling when Diana is farming safely to deny her scaling and objective access.
Use (Q) and (R) to engage skirmishes around dragon and Rift Herald when lanes can follow, enabling snowball through kills and objective control.
Leverage Briar's extended fight strength to clean up dives and teamfights, snowballing leads into mid-game map pressure and objective dominance.
