How to win lane as Sion against Zac · 49.11% win rate over 1,468 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Zac has no damage at level 1 — step on blobs to cut his passive healing and farm safely; neither side can force a kill here. |
| Level 2 | Sion | Your W-shield comes up and his first W-slap is easy to absorb — detonate it for chip and land a short charged Q to establish lane pressure. |
| Level 3 | Sion | His E slingshot is online but fully telegraphed — hold a charged Q to stun him on landing and punish whiffs with a free E-armor-shred follow-up. |
| Levels 4-5 | Even / skill | Zac kites in and out on E cooldown and sustains blob-by-blob; respect the engage range and don't charge Q into open air where he can disengage. |
| Level 6 | Even / skill | Your R gives you an intercept tool for his E landing zone and your slingshot-punish window opens — neither side decisively owns this stage. |
| First item | Sion | Heartsteel HP stacks compound on your kill-passive; sustained brawls with W-shield active favor you and Zac's low damage-per-second can't outpace your bulk. |
| Two+ items | Even / skill | His Cell Division blobs give him a revive threat that cancels late kills; step on the blobs or W-detonate them — if you do, your zombie passive still deals damage when he tries to finish you. |
Zac has almost no damage at level 1 — his Q (Stretching Strikes) does poke but he needs blobs from his W (Unstable Matter) and passive to sustain through anything. Step on every blob he drops so his healing is cut off, and use Q at tip range to land free chip without giving him a target. At level 2 your W-shield goes up and you can absorb his first real trade; let him W-slap you, shield it, then answer with a short-charged Q to shove him off. At level 3 his slingshot is online but it telegraphs from far away — point your body toward the likely landing zone and hold the charged Q so you stun him the instant he touches down.
