Playing against Kassadin

How to counter and exploit weaknesses

1

Punish Kassadin VERY hard in early game (levels 1-5): he's one of the weakest champions at that stage.

2

AD champions in midlane counter him: his passive and Q shield only work against magic damage.

3

Do NOT let the game go to late game: a level 16 Kassadin with his items is nearly impossible to stop.

4

His R consumes a lot of mana when stacking — force him to use multiple Rs to drain his mana.
