At a glance

Bully the melee mage all lane — but every spell you cast feeds his shield; poke with E placement and autos, save Q for the post-shield window.

Track: Kassadin's R — Riftwalk (5–2s cooldown). His mobility spike — the lane is decided before it scales.

Do

  • Bank Q exclusively for his engage
  • Keep the wave centered and flanks warded
  • Shove and ping every roam window

Don't

  • Q-poke near his engage timers
  • Shove past river post-6
  • Greed the E detonation at half HP

How to beat Kassadin as Lux: the early game

You dominate the early lane. Kassadin is immobile and his Q shield is delayed, so your E-Q poke zones him off farm and chunks him every time he walks up. Slow-push, deny his CS, and build the biggest lead you can before his 6 spike arrives. Track Riftwalk: 5s at rank 1, 3.5s at 2, 2s at 3 — it never really goes down, so stop waiting for it.
