Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillAt level 1 you have only one turret and no grenade stun, but Kassadin is just as feeble — no waveclear and a passive shield that does nothing offensively — so the contact window is a wash.
Level 2HeimerdingerYour second H-28G turret plus the slowing electron beams turn the lane into a zone a waveclear-less, Riftwalk-less Kassadin simply cannot fight into.
Level 3HeimerdingerThree turret charges out-DPS anything Kassadin can do pre-items, and he has no R blink yet to escape the nest or dodge the beams.
Levels 4-5HeimerdingerFull nest plus the CH-3X center-stun grenade is your peak — a Kassadin who steps in to farm gets locked and deleted under the beams.
Level 6HeimerdingerRiftwalk at 6 is only a short blink, not burst — UPGRADE!!! banks you a super-turret or a wider stun and you still own the architecture war.
First itemHeimerdingerYour three-turret siege power lets you keep zoning a Kassadin whose single AP item still can't burst through the buildings.
Two+ itemsKassadinHe out-scales hard: two-item Riftwalk blinks past your turrets and his Q-silence-into-burst kills your immobile yordle before the beams matter — his window, not yours.

Early game (levels 1–5)

Kassadin is one of the saddest early laners in the game — no waveclear, a passive magic shield that does nothing to push, and no Riftwalk until 6 — so once your second turret and the slowing electron beams are up around level 2-3 you simply wall him off the wave. Plant the nest on his side of the lane and let the beams tax every last-hit he reaches for. Don't overstep into his Q silence range at level 1 when you only have one turret and no grenade stun, but the moment the full setup is down he physically cannot trade into the buildings.
