Karthus vs Zac

Updated Jun 4, 2026

Overview

Prioritize full clears and avoid early river fights where Zac can leverage his long-range engage to punish you.
This is a scaling versus engage frontline matchup; focus on farming tempo and vision to avoid Zac's early ganks and invades.

Jungle Plan

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 long-range engage.
Track Zac's pathing to anticipate his ganks and be ready to counter-gank or avoid early fights.

Danger windows

Zac's early invade attempts before you finish your first clear can disrupt your tempo; avoid isolated river fights early.
Be cautious contesting objectives or Scuttle without vision, as Zac's engage 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.

Early game

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

Power spikes

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

Win conditions

Convert your faster clear speed and item spikes into early objective control by arriving first with vision.
Use (R) 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.
