Zac must survive early invades and avoid isolated river fights to reach his scaling frontline power spike.
Use long-range (E) ganks from fog angles to bypass Nunu's usual warding and create pressure before objectives.
Jungle Plan
Prioritize full clears or defensive pathing early to protect camps and avoid Nunu's faster clear and early ganks.
Use (E) to gank lanes from fog or walls, exploiting angles Nunu can't easily contest.
Track Nunu's position and counter-gank when he commits to early objectives or ganks, leveraging Zac's tankiness and crowd control.
Danger windows
Zac is vulnerable to early invades and isolated river fights before level 6 due to low dueling strength and Nunu's sustain.
Be cautious around first dragon spawn when Nunu can quickly start with (Q) and Smite; avoid fighting without lane priority or vision.
Avoid low-health clears or forced smite fights where Nunu's objective control and healing outmatch Zac's durability.
Early game
Start with a full clear away from river to avoid early Nunu invades and secure level 3 safely.
Contest first Scuttle only if nearby lanes have priority to avoid 2v2 disadvantage against Nunu's strong early pressure.
Avoid river fights before level 6 unless lanes collapse or you have vision and numbers advantage.
Power spikes
Level 6 unlocks Zac's (R) knockup, enabling stronger objective fights and ganks; use this to force fights around dragon or Herald.
After first completed tank item, Zac's frontline durability increases, allowing safer objective control and engage.
Nunu's first dragon or Herald start with (Q) and Smite is a power spike; Zac must contest vision and force fights before Nunu secures objectives.
Win conditions
Survive early game by full clearing and avoiding risky river fights until level 6 and tank items.
Use long-range (E) ganks from fog to generate lane priority and force Nunu into reactive plays.
Translate gank pressure into vision control and objective setups around dragon and Rift Herald to leverage Zac's strong engage and frontline scaling in teamfights.
