Nasus must prioritize safe full clears and avoid Zac's early invade attempts due to his low invade resistance and Zac's strong early gank threat.
Focus on scaling through controlled farming and leverage superior late-game dueling with high (Q) stacks and (R) durability to outscale Zac's engage tank role.
Jungle Plan
Prioritize full clears and contest the first Scuttle only if nearby lanes can move first and provide support.
Use lane priority to force Zac away from river fights and invade his jungle camps when he commits to ganks.
Secure early dragon vision and objective control to leverage scaling and force Zac into reactive plays.
Danger windows
Zac's early invade window before level 4 is dangerous; avoid isolated jungle fights and respect his long-range (E) engage angles.
Isolated river fights without lane priority are risky; contest Scuttle or objectives only when allied lanes can follow or counter-gank.
Low-health clears or forced smite fights around early dragon can be lost if Zac has vision and lane control; maintain health and vision before committing.
Early game
Start with a full clear to reach level 4 before contesting Scuttle or river control to reduce risk from Zac's early pressure.
Avoid early river fights unless allied lanes have clear priority to support counter-ganks against Zac's long-range (E) ganks.
Use vision to track Zac's pathing and prepare to counter-invade when he commits to the opposite side of the map.
Power spikes
Level 6 (R) grants Nasus durability for extended fights; hold ground if Zac commits but avoid fights Zac can disengage from.
High (Q) stacks create a major dueling threat; pressure side lanes once stacks and (R) are available to punish Zac's weaker dueling.
Zac's tank and engage scaling improves objective fights; Nasus must outscale by stacking and choosing fights wisely post-level 6.
Win conditions
Convert safe early clears and vision control into counter-invades on Zac's camps to delay his scaling.
Use lane priority and high (Q) stacks to pressure side lanes, forcing Zac to respond and opening objectives for your team.
Leverage superior late-game dueling and (R) durability to win extended fights and secure dragon or Rift Herald with team support.
