Elise must leverage her very high early gank threat and dueling power to snowball lanes before Sejuani's scaling and teamfight engage come online.
Prioritize aggressive three-camp clears into early river control and invades to punish Sejuani's slower, controlled pathing and avoid giving her free scaling time.
Jungle Plan
Invade Sejuani before her first reset when lanes have priority to deny her farm and force weak clears.
Fight for river control and first Scuttle only when your lanes can collapse to secure vision and objective setup.
Prioritize early ganks or dives on lanes with strong follow-up to snowball leads and deny Sejuani's scaling.
Danger windows
Beware of Sejuani's level 6 (R) engage around objectives and avoid isolated river fights without lane support.
Avoid fighting for objectives when Sejuani has vision control and her frontline durability lets her absorb cooldowns.
Be cautious during low-health clears or forced smite fights where Sejuani's CC chains and tankiness can turn fights.
Early game
Start with a three-camp clear to hit level 3 quickly and look for early ganks or a counter-invade before Sejuani finishes her first clear.
Contest first Scuttle when nearby lanes can move first and avoid fighting Sejuani isolated without lane priority.
Use early wards to track Sejuani's path and avoid full clears into her stronger objective control windows.
Power spikes
At level 3, Elise's burst and (E) cocoon enable lethal early ganks; use this to force Sejuani off camps or lanes.
Respect Sejuani's level 6 (R) long-range engage by avoiding grouped fights in narrow objective entrances.
Sejuani's first tank item spike increases her durability in fights; control river entrances and force fights where allies can capitalize on her CC setup.
Win conditions
Use Elise's early gank and invade strength to deny Sejuani free farm and scaling by punishing her slower clears.
Convert early leads into dragon and Rift Herald control by securing river vision and forcing fights on your terms.
Maintain tempo advantage by tracking Sejuani's pathing and counter-ganking her early pressure to snowball lanes and objectives.
