Use Briar's high clear speed and dueling to punish Skarner's medium invade resistance by invading only with lane priority or exit paths secured.
Focus on volatile lanes and countergank windows to leverage Briar's high early game pressure and gank threat against Skarner's terrain-dependent engage.
This is a snowball vs teamfight matchup where Briar must convert early tempo into objective fights and cleanup dives before Skarner's frontline control scales.
Jungle Plan
Path through camps that lead to volatile lanes where your team can follow up on (Q) and (R) engages for effective ganks.
Contest first Scuttle only when your lanes can move first and hold river control to deny Skarner's objective setups.
Use tempo advantage to invade Skarner's jungle cautiously with exit routes, aiming to deny his scaling by stealing camps and forcing him into unfavorable fights.
Danger windows
Respect Skarner's early jungle pressure around wall-heavy gank lanes and avoid isolated river fights without lane priority.
Avoid forced smite fights near objectives where Skarner's tankiness and suppression can punish overcommitment.
Be cautious during low-health clears or after failed frenzy commits, as Skarner's high invade resistance and terrain control make counter-invades risky.
Early game
Start full clear to maintain tempo and look for early river Scuttle only if nearby lanes have priority to avoid Skarner's terrain traps.
Avoid early isolated fights unless you have vision and lane backup, as failed frenzy commits can be punished by Skarner's suppression and stun.
Track Skarner's pathing toward wall-heavy lanes and be ready to counter-gank his early pressure around objectives.
Power spikes
Briar's power spikes come from healthy clears enabling extended skirmishes and (Q)/(R) engage combos; use these to force fights before Skarner can frontline.
Respect Skarner's power spike when he controls terrain near objectives and has (E) and (R) available for suppression and crowd control.
Briar's scaling into sustained damage and cleanup fights outpaces Skarner's tank frontline, so prioritize fights where you can stay attached and avoid kiting.
Win conditions
Convert early clear tempo and protected skirmishes into objective control by securing dragons and Rift Herald with vision and lane priority.
Use (Q) and (R) to create sticky engages in lanes that can follow, snowballing through counter-ganks and dive cleanups.
Deny Skarner free farm by invading with exit information and force him into fights where his lack of DPS and kiting make him vulnerable.
