Karthus into Zacmedium

Overview

Prioritize full clears and avoid early river fights where Zac can punish with engage.
Focus on farming tempo and vision to dodge Zac's long-range ganks and invades.
Use your superior clear speed to reach item spikes before Zac forces fights or invades.

Cycle camps quickly to hit item spikes before Zac can force fights or invade.
Only contest river Scuttle when nearby lanes have priority to reduce risk from Zac's engage.
Track Zac's pathing to anticipate his ganks and be ready to counter-gank or avoid early fights.

Zac's early invade attempts before your first clear finishes can disrupt your tempo; avoid isolated river fights early.
Be cautious contesting objectives or Scuttle without vision, as Zac's and knockups can force bad fights.
Low-health clears or forced smite fights against Zac risk losing tempo and objectives; ensure lane priority or vision advantage before committing.

Start with a full clear path and ward jungle entrances to prevent Zac's early invade attempts.
Avoid fighting Zac early unless your lanes have strong priority and vision for counter-ganks.
Delay Scuttle contests until you confirm Zac's location and nearby lanes can assist or respond quickly.

Level 6 unlocks global damage; use it to finish fights or punish low-health targets after Zac commits.
First AP item spike boosts clear speed and objective damage; leverage this to cycle camps faster and secure objectives.
Respect Zac's engage potential before he gains tank stats and team follow-up, especially pre-level 6.

Convert your faster clear speed and item spikes into early objective control by arriving first with vision.
Use after Zac or his laners commit to fights to secure kills or force resets.
Deny Zac tempo by tracking his ganks and counter-ganking to keep him off your camps and scaling path.
