Early game (levels 1–5)

Levels 1-5 are all yours. Kassadin is one of the weakest laners in the game before 6, so shove the wave into him, deny CS, and all-in with W+Q whenever he steps up for a caster minion. He has no way to fight back and his only defense is to Q-silence and back off. Every point of farm you deny pushes his Riftwalk spike later.
