Sejuani vs Rengar

Updated Jun 6, 2026

Overview

Sejuani controls river and objective entrances with tankiness and reliable CC to counter Rengar's early invade threat.
Focus on measured pathing that leverages melee lane synergy and avoids isolated fights where Rengar's burst and mobility dominate.

Jungle Plan

Secure first Scuttle only when allied lanes provide priority and vision control to prevent Rengar's stealth picks.
Invade Rengar's jungle after tracking his position on the opposite side or when allies can collapse.
Use tempo leads to contest dragon, Rift Herald, and Void Grubs focusing on grouped fights where Sejuani's CC chains excel.

Danger windows

Early invade and river fight windows are dangerous without vision and lane priority.
Avoid isolated jungle skirmishes after using mobility or Smite, as Rengar can punish cooldowns with burst.
Losing lane priority around Scuttle, dragon, or Herald turns river control into a high-risk zone.

Early game

Start with a full or controlled clear toward melee lanes that have priority to enable safe early Scuttle contests.
Avoid early river fights without allied lane priority to prevent Rengar's brush ambushes.
Opt for cross-map camps if first Scuttle contest is too risky due to lack of vision or lane priority.

Power spikes

Level 6 unlocks (R) for long-range engage, enabling Sejuani to start fights or catch Rengar out of position.
First tank item completion boosts durability, allowing frontline presence and extended objective control.
Two tank items solidify frontline CC role, making it safer to force grouped fights despite Rengar's pick potential.

Win conditions

Translate jungle tempo into securing dragon and Rift Herald by establishing vision and forcing grouped fights.
Deny Rengar's scaling by invading camps when lanes can support and contesting objectives with CC chains.
If outnumbered, trade tempo into top-side camps, Void Grubs, or vision control instead of forcing risky dragon fights.
