Bully the shield off him every wave — but the chain feeds his passive; lead with W damage and save Q-E for the popped windows; end before three items.

Read from LeBlanc's seat: which stage windows this plan plays for against Kassadin.
This is LeBlanc's own plan; across 2,675 pooled games the lane is leaning Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | LeBlanc | Level 1 favours LeBlanc as Kassadin is mana-starved with zero kill pressure this early |
| Level 2 | LeBlanc | Level 2 stays LeBlanc-favoured for the same reason, plus he still lacks any engage tool |
| Level 3 | LeBlanc | Level 3 favours LeBlanc since her burst chain punishes his continued passivity while waiting for level 6 |
| Levels 4-5 | LeBlanc | Levels 4-5 stay LeBlanc's: every spell you cast near him charges Force Pulse, so poke from 925 with E and W-return before the cone — one clean rotation still threatens a kill |
| Level 6 | Even / skill | Level 6 is skill: Riftwalk is 5s at rank 1, so he leaves your chain — but Null Sphere still eats your burst |
| First item | Kassadin | First item favours Kassadin: Void Stone cuts your magic damage and Rod of Ages ends your kill window |
| Two+ items | Kassadin | 2+ items favours Kassadin — Riftwalk drops to 2 seconds and Void Stone plus MR stacking makes your burst a nuisance, not a kill |
Levels 1-2 Kassadin farms with Nether Blade, a 7-second auto reset that restores mana, so chip damage does not starve him — poke only when Null Sphere is down. Track Riftwalk is 5s at rank 1, 3.5s at 2, 2s at 3, and stacking casts cost escalating mana — his escape is only gone when his mana bar is. Before level 6 Kassadin has no escape, but Null Sphere shields magic on a 9s cooldown and Void Stone cuts your damage — force the orb out, then run the full Q-W-E chain.
