Kassadin Counter for Mid

Patch 12.10

A good Kassadin will time his you to deal damage to you, as well as block your magic damage with the resulting shield. Counter Kass by pushing the wave and forcing him to use to farm. You can poke him when his Q is down.

Before Kassadin reaches Level 6, he has no mobility. If you are able to freeze the wave on your side of the river, Kassadin has to overextend to farm and makes for an easy gank.

If Kassadin did not take Fleet Footwork, it makes it very hard for him to sustain in lane. You can counter Kassadin by poking him out of lane and delaying how quickly he can scale.

Late game Kassadin is a monster. But even in the late game, Kass is countered by hard cc. Kassadin's tankiness comes from healing when he does damage to champions. CC and burst him early to win the fight.

Kassadin is extremely mobile after he has his ult and has stacked mana items. Counter Kass when he roams by quickly shoving waves or taking a different objective. Also be careful of overextending if you are pushing a side wave.

Exhaust is the best Kass counter. If you think your team will have trouble against a late game Kass, make sure to take Exhaust over Ignite or Heal. Exhaust gives you a chance to kill Kass and win the fight.
