Use Gragas's medium early pressure and strong gank threat with (E) and (R) to contest river and influence lanes before Sejuani scales.
Prioritize objective control by leveraging (R) to disrupt Sejuani's frontline and deny her smite access.
Manage cooldowns and avoid slow full-clear handshakes against Sejuani's tanky engage to maintain invade resistance.
Jungle Plan
Path to lanes with melee allies that can follow up on your (E) engage for high-impact ganks.
Contest dragon and Rift Herald entrances using (R) to separate Sejuani from her team and secure objectives.
Counter-jungle when Sejuani commits to slow clears or grouped fights, using your mobility and burst to punish her lower duel damage.
Danger windows
Beware early river fights where Sejuani arrives first with melee allies ready to stack (E) and chain CC.
Avoid low-health clears that leave you vulnerable to Sejuani's tanky engage and crowd control.
Respect her (R) availability before objective fights to prevent getting caught in long-range stuns or forced smite contests.
Early game
Opt for a three-camp clear to reach level 3 quickly and pressure lanes where (E) can force flashes or kills.
Fight for first Scuttle only if nearby lanes have priority to secure river control and deny Sejuani vision.
Avoid extended early duels; instead, hold flank angles before objectives to set up counter-ganks or invade safely.
Power spikes
At level 6, use (R) to isolate targets or disengage Sejuani's engages; respect her (R) for long-range initiation.
After your first AP or tank item, leverage improved burst or durability to trade confidently and force Sejuani into unfavorable fights.
Respect Sejuani's level 6 (R) and first tank item spikes, which enhance her engage and frontline presence around objectives.
Win conditions
Convert early gank pressure and Scuttle control into secured dragons and Rift Heralds by disrupting Sejuani's frontline with (R).
Use your (E) and (R) to punish overextended lanes and force Sejuani into unfavorable skirmishes or counter-jungling scenarios.
Deny Sejuani free farm and scaling by invading camps when she commits to grouped fights, then leverage your burst and disengage tools to snowball leads into teamfight advantages.
