Zac vs Ekko Counter Pick

Chronobreak is Ekko’s answer to the matchup. Zac relies on a long-range Elastic Slingshot, marks targets with Stretching Strikes, and wears down health through Unstable Matter. Ekko’s ultimate sends him back to an earlier position with more health, a few seconds in the past, and he cannot be targeted while it resolves. In 481 games on patch 16.13.1, Zac wins 44.5%.

• Damage: Ekko deals mixed damage, so Zac’s 112.9 armor and 32 magic resistance at level 18 only partly stop him, splitting his defense into two imperfect answers.
• Body: Zac ends up with 2,538 health to Ekko’s 2,338, yet at level 1 it is 655 against 685, so the early lead is smaller than his tank reputation implies.
• Mobility: Phase Dive lands Ekko on his target with the follow-up attack, while Timewinder slows enemies on the way back.

Both champions score 8 on difficulty and both lean on skillshots rather than instant effects, so whoever reads the other first usually wins the exchange. Z-Drive Resonance gives Ekko bonus magic damage and a speed burst on every third hit against one target, which rewards long fights against a 685-health opponent. Zac’s answer is Cell Division: he reclaims the chunks he sheds mid-fight and splits apart rather than dying when the final damage arrives. The only trade that reliably pays off is forcing that ultimate out before Ekko has it back. Move speed matches at 340, and Zac has no resource to drain, so each failed attempt costs him only cooldowns, whereas Ekko’s poke keeps charging him a price.
