Zac must survive Rek'Sai's early high-tempo invades and ganks by playing around vision and avoiding river fights before level 6.
Focus on scaling into a frontline engage role where Zac's long-range (E) and disruption (R) turn grouped fights and objectives in your favor.
Jungle Plan
Prioritize controlled full clears and avoid early river duels unless your lanes collapse first, then counter-gank with your crowd control.
Use your long-range (E) to gank lanes vulnerable to Rek'Sai's tunnel angles, forcing Rek'Sai to respond defensively.
Focus vision control around dragon and Rift Herald to enable objective turns and deny Rek'Sai early numbers advantages from tunnel revisits.
Danger windows
Rek'Sai's early three-camp clear into invade creates high risk for Zac before level 6; avoid isolated river fights and low-health clears.
Forced smite fights around early Scuttle or dragon can be dangerous if Rek'Sai has lane priority or better vision.
Rek'Sai's tunnel knockup (W) and execute (R) chase make isolated counter-jungling or overextended ganks risky before your crowd control is online.
Early game
Start with a full clear or a safe path away from Rek'Sai's early three-camp invade to avoid being punished before level 6.
Contest first Scuttle only if nearby lanes have priority and Rek'Sai's tunnel paths are tracked to avoid surprise counter-invades.
Use lane fog and wall angles for early ganks instead of predictable river approaches to maximize (E) gank threat and avoid Rek'Sai's knockup (W).
Power spikes
Level 6 is a major spike; Zac's (R) knockup and disruption enable strong counter-ganks and objective fights, forcing Rek'Sai to respect your engage.
Zac's tank scaling after first core items improves frontline durability, allowing safer objective control and teamfight initiation.
Rek'Sai's early level 3 with tunnel access increases invade and gank threat; avoid fights until you reach your own level 6 and tank items.
Win conditions
Survive early invades and full clears to reach level 6, then leverage your long-range (E) and (R) to set up ganks and counter-ganks.
Use vision and lane priority to control dragon and Rift Herald, turning objective fights with your tank engage and disruption.
Deny Rek'Sai free farm by tracking her pathing and punishing overextensions with your crowd control and engage angles, scaling into a frontline force for teamfights.
