Out-combo him — step on his blobs, snowball.
Track: Zac's E — Elastic Slingshot (21–9s cooldown). His engage. Bait it.
Read from Riven's seat: which stage windows this plan plays for against Zac.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Riven | Stretching Strikes reaches 800 to your 275, but it is his only Level 1 threat — space it, stack Runic Blade off the wave, and step on every blob to deny his sustain. |
| Level 2 | Riven | W stun comes online and Zac has no escape tool yet — bait his Unstable Matter W with your E shield then lock him in place and run the full combo before he can react. |
| Level 3 | Riven | Full Q-W-E chain at Level 3 bursts Zac faster than his blob sustain can answer — the lane is yours if you keep trading on his W cooldown. |
| Levels 4-5 | Even / skill | Elastic Slingshot is live and he can threaten a catch — respect the brush angles and trade only when you can see the cooldown bar, making this a skill-check positioning phase. |
| Level 6 | Riven | Blade of the Exile's extended range punishes his Elastic Slingshot landing directly, and your one Wind Slash lands before the blobs he shed can be reabsorbed for the heal. |
| First item | Riven | Your first-item spike outpaces his tank-item ramp — he is not yet durable enough to absorb your full combo, so force the all-in the moment your item completes. |
| Two+ items | Even / skill | Full-tank Zac with Heartsteel and Sunfire absorbs your burst and his passive resurrection makes finishing him genuinely difficult — push your lead through objectives, not solo kills. |
Zac at Level 1 is just a slow melee tank farming — Q your way onto him and weave autos to stack Runic Blade charges, and step on any blobs he drops to kill his passive sustain before it heals him back. The moment W comes online at Level 2 you can all-in: walk up, bait his Unstable Matter W by pre-activating E shield to eat the slam, then stun him and run the full Q-chain while he is locked in place. At Level 3 the pattern solidifies — he cannot match your burst in a short trade and his only answer is to disengage, which he cannot reliably do without Elastic Slingshot.

Riven, slightly — a 51.63% win rate edge over 889 games; execution can flip it.
Mostly — Riven has a small statistical edge (51.63% win rate), but execution decides this lane far more than the pick does.
Not a hard counter — Riven has a slight edge (51.63% win rate), and play quality decides the rest.
Riven takes Conqueror on the Precision tree with Triumph, Legend: Alacrity and Last Stand, and Resolve secondary (Bone Plating and Unflinching) vs Zac.
Start Doran's Blade + Health Potion and back for Executioner's Calling (≈800g) — cuts his healing. Build Eclipse (burst + spellblade tempo) first, then Sterak's Gage, with Plated Steelcaps.
