Malphite vs Zac Counter Pick
Matchup Summary
What the Data Means
At 108 games the evidence is thin, so 40.7% on patch 16.13.1 reads as a direction rather than a precise verdict. The mechanical case behind it is straightforward. Unstable Matter deals a percentage of maximum health as magic damage, and Malphite is the champion who wants 665 base health growing to 2,433 by level 18. Every point he adds makes that ability hit harder, and his 28 base magic resist is the lowest defensive value he owns.
Zac also refuses to die on schedule. Cell Division sheds chunks he can reabsorb for health whenever an ability lands, and fatal damage splits him instead of killing him outright, all on a tank frame of 685 base health and 2,538 at level 18 with no resource bar to manage. Malphite spends mana on every cast; Zac spends nothing.
The engagement contest is closer than the win rate suggests. Elastic Slingshot and Unstoppable Force are both long-range telegraphed initiations, and whoever fires one into the other’s cooldown wins the exchange. Granite Shield’s 10% absorb favours Malphite in short bursts, while Let’s Bounce! rewards the longer version. Zac also strikes from 175 against 125 and moves at 340 against 335, so he usually chooses when the exchange begins. Building magic resist ahead of more health is the counterintuitive but correct response at difficulty 2 against difficulty 8.
