Read from Sejuani's seat: which stage windows this plan plays for against Zac.
This is Sejuani's own plan; across 82 pooled games the lane is Zac-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both champions are level-1 melees with no reliable poke and identical levels of early threat — take W, hit minions, and accept that nothing happens here. |
| Level 2 | Even / skill | Stretching Strikes is an 800-unit grab, not a bounce — it drags you toward him. Last-hit, count Elastic Slingshot at 21s at rank 1, and give him nothing before you step up. |
| Level 3 | Even / skill | Full Q-W-W-E combo stuns him mid-lane before his blob passive can undo the trade — this is the first window where landing your pattern matters. |
| Levels 4-5 | Even / skill | Frost Armor makes you immune to his Stretching Strikes and Let's Bounce! slows until his damage strips it — fight on the buff, with Elastic Slingshot down and Frost ready. |
| Level 6 | Sejuani | Glacial Prison arrives and you now have a CC tool with longer range than his Elastic Slingshot — you can initiate the decisive trade or punish his slingshot landing with an immediate comet counter. |
| First item | Even / skill | Sunfire Aegis burn denies the blob passive healing that sustains him through chip trades, and your Frost stacks detonate into Permafrost stun more reliably once you have the durability to stick on him. |
| Two+ items | Even / skill | Both of you are teamfight anchors at full build — but check Cell Division before you spend R on him, because a revive turns your 120-second ultimate into a delay. |
At levels 1 and 2, this is two tanks doing absolutely nothing to each other — take W, last-hit safely, and refuse to trade without Frost stacks built up. His passive blobs make him regenerate chip damage faster than most top laners, so short trades favor him; any poke you take heals back with blobs before you can punish. At level 3 your full Q-W-W-E combo is online, and the first time he walks up to last-hit a minion, you Q onto him, double-sweep W for full Frost stacks, and hit E Permafrost to stun him in place — that is real damage on a tank mirror and you walk away clean.
