Read from Heimerdinger's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | At level 1 you have one turret and no grenade stun, but Kassadin is feebler — no waveclear, and Void Stone only cuts magic damage — so your turret out-trades his 650 Null Sphere poke. |
| Level 2 | Heimerdinger | Your 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 3 | Heimerdinger | Three 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 4-5 | Heimerdinger | Full 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 6 | Heimerdinger | Riftwalk 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 item | Heimerdinger | Your three-turret siege power lets you keep zoning a Kassadin whose single AP item still can't burst through the buildings. |
| Two+ items | Kassadin | He out-scales hard: rank-3 Riftwalk blinks past your turrets every 2s and Null Sphere into Nether Blade kills your immobile yordle before the beams matter — his window. |
Kassadin is one of the saddest early laners in the game — no waveclear, Void Stone only cuts magic damage taken, 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. Stay outside Null Sphere's 650 range at level 1 when you have one turret and no grenade stun; after that his 650 poke cannot answer three buildings and 1325-range rockets.
