Read from Xerath's seat: which stage windows this plan plays for against Kassadin.

StageFavouredWhy
Level 1XerathAt level 1 melee Kassadin can't answer your Q, so the range and poke are entirely yours.
Level 2XerathAt level 2 he still has no push or escape and eats your charged Q on every CS approach.
Level 3XerathLevel 3 gives you E and W to pop his shield, making him a prime pre-6 all-in and gank target.
Levels 4-5XerathThrough levels 4-5 shoving denies his XP while your W-Q poke keeps him starved, favouring you.
Level 6XerathAt 6 you still control the lane by punishing Riftwalk-ins with E and R poke from range.
First itemEven / skillAt first item your poke lead holds even as his magic resist begins to blunt you, so cash it now.
Two+ itemsKassadinLate scaling flips toward Kassadin, so the you-favoured window is the early and mid game you must exploit.

How to beat Kassadin as Xerath: the early game

Levels 1-2 are entirely yours: Kassadin is melee, has no push, and takes reduced-value trades because his Null Sphere only shields one magic hit. Start Q, shove the first wave, and charge Q on him every time he approaches a minion. He can do nothing back at this range, so tax his HP and set up an early all-in or deny him CS outright. This is the phase where you build the lead you'll need.
