Read from Kassadin's seat: which stage windows this plan plays for against Zac.
This is Kassadin's own plan; across 141 pooled games the lane is leaning Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both of you are weak at level 1 - he only has one ability and you only have Null Sphere, so deny his last-hits and set up the lane. |
| Level 2 | Zac | Zac edges it: his E slingshot and Q grab let him pin you from fog while you have no blink to escape. |
| Level 3 | Zac | He still owns it at 3 - his Q grab and Unstable Matter out-trade your mana-hungry Q before you have any escape tool. |
| Levels 4-5 | Even / skill | It levels out as Nether Blade's mana sustain and a maxed Q shield let you weather his blob-pickup poke and farm safely. |
| Level 6 | Kassadin | Riftwalk unlocks - you blink out of his E sling pin, and Void Stone's 15% magic reduction blanks his W burst. |
| First item | Kassadin | Your Catalyst into Rod of Ages stall plus Q shield lets you out-sustain his poke and stop being free engage bait. |
| Two+ items | Kassadin | Zac has no late scaling to reclaim, but Cell Division revives him out of four bloblets every five minutes - clear the blobs or the kill does not count. |
Zac owns the opening because his E slingshot reaches you from fog and his Q grab can pin you while you have nothing but Null Sphere and no blink yet. Don't step up to last-hit near unwarded brush - one E pin into Q grab and you eat his full combo with no way out. Farm with the tip of Q, ward his sling angles, and accept that levels 2-3 are about surviving his all-in, not contesting it.
