How to win lane as Locke against Kassadin · Matchup data reviewed on patch 26.15

Verdict: Kassadin has the tempo edge — Kassadin pressures 3 of the 7 stage windows.

At a glance

An assassin mirror-war where your passive votes last — whoever hits 40% first is playing YOUR game, not his.

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

Do

  • Dodge or minion-block Riftwalk before anything else
  • Blink AFTER his engage tool is spent
  • Force fights at 40-50% HP where your passive out-maths him

Don't

  • Coin-flip the level 2 all-in
  • Burn E while his kill combo is up
  • Stay in Purgatory range of HIS burst at low HP — the execute game cuts both ways

How to beat Kassadin as Locke: the early game

Levels 1-2 are skill-based: Kassadin is weak and melee, so you can poke, but his Q shield eats your magic damage so you must mix in autos to make trades count. Your job is to shove and punish before he scales; his Q shields your magic damage, so weave autos and physical poke and force him to trade or miss CS under tower.
