Rek'Sai is a high-tempo early-game jungler who must leverage fast clears and tunnel ganks to snowball before Ivern's utility scales up.
Focus on invading and contesting camps aggressively to deny Ivern's slower clear and limited dueling power while controlling river vision and Scuttle crabs.
Jungle Plan
Path for early aggressive three-camp clears followed by invading Ivern's jungle before he can safely share buffs or complete his marked camps.
Contest river control and Scuttle crabs when your lanes can assist, using tunnel mobility to set up ganks or counter-ganks.
Use vision and map pressure to deny Ivern's camp pickups and force him into defensive routes, then capitalize on his low objective damage by securing dragons and Rift Herald early.
Danger windows
Avoid isolated river fights before level 3 or without lane priority, as Ivern can use his root (Q) and shield slow (E) to punish overextensions.
Be cautious during forced Smite fights on objectives where Ivern's team utility and Daisy knockup (R) can turn the tide.
Respect moments when Ivern's lanes have strong priority or crowd control ready, limiting your safe invade and counter-gank options.
Early game
Start with a three-camp clear into an early invade or counter-invade to punish Ivern's medium clear speed and limited dueling.
Prioritize first Scuttle fights only when nearby lanes have priority to avoid risky isolated river skirmishes.
Use tunnels to quickly rotate between camps and lanes, enabling fast counter-ganks against Ivern's slower jungle pathing.
Power spikes
Rek'Sai's early level 3 and tunnel access create strong gank and invade windows; use these to force Ivern off camps and snowball.
Ivern's utility spikes with Daisy and shields later; respect his knockup (R) and root (Q) when grouped but exploit his weak early dueling.
Rek'Sai's (W) knockup and (R) execute are key to securing kills early; coordinate ganks to maximize these crowd controls.
Win conditions
Convert early jungle tempo into repeated tunnel ganks on flashless or low-mobility lanes to snowball leads.
Deny Ivern free farm by invading marked camps and controlling river vision to isolate him from teammates.
Use early numbers advantage and objective control to secure dragons and Rift Herald before Ivern's utility scaling becomes impactful.
