Zac vs Ambessa Counter Pick
Matchup Summary
What the Data Means
Zac has no resource bar at all, while Ambessa spends Energy, so neither can be drained out of a fight the way a mana-based champion can. The bigger gap is how hard each one is to pilot. She sits at the top of the difficulty scale with a 10, while he rates an 8. Across 133 games on patch 16.13.1, Zac wins 54.1% of the time.
On raw stats the two are nearly even. Zac starts with 685 health and 33 armor to Ambessa’s 630 and 35, then finishes at 2,538 health and 112.9 armor against her 2,500 and 118.3. She is a touch sturdier against hits, he a touch bulkier overall. Their damage types cancel neatly: his is magic, hers physical, so each gets resistances the other doesn’t need to worry about. Zac also has the reach edge, 175 to 125, which matters for Unstable Matter, a spell that strips a percentage of maximum health from every enemy nearby. Cell Division is where his real advantage lies. Fragments shed when abilities hit him heal him once reabsorbed, and a lethal blow splits him in two instead of killing him, so Ambessa has to land Public Execution twice or not bother at all. Her Drakehound’s Step demands perfectly ordered inputs, and any slip leaves her caught inside Let’s Bounce!, which knocks enemies airborne on all four bounces. Movement speed widens the picture slightly at 340 against 335, so Zac usually determines whether a fight starts. Both kits are on the Zac and Ambessa entries.
