How to win lane as Kassadin against Nasus · 52.37% win rate (443 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Survive the bully — every minute you're alive pre-6 is a minute closer to him being unable to play.
Track: Nasus's W — Wither (15–11s cooldown). His only answer to kiting — bait it before you commit.
Read from Kassadin's seat: which stage windows this plan plays for against Nasus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both of you are weak at level 1 — you have only Null Sphere and no escape, he has only Siphoning Strike, so neither commits. |
| Level 2 | Nasus | Nasus starts stacking Siphoning Strike and Withers you out of any contest while you have no Nether Blade mana sustain yet. |
| Level 3 | Kassadin | Nether Blade restores your mana on empowered autos and a maxed Null Sphere shield lets you safely farm under tower — you stabilize. |
| Levels 4-5 | Kassadin | Riftwalk gives you the mobility to leave his Wither-setup ganks — a movement slow cannot shorten a 500-unit blink. |
| Level 6 | Kassadin | Catalyst into Rod of Ages stalls you to parity — Void Stone is wasted on his physical Q, but the HP and mana stall holds the lane. |
| First item | Kassadin | With Riftwalk's escalating charges you roam and assassinate squishies, sidestepping the 1v1 you can't win into a stacked Nasus. |
| Two+ items | Nasus | Full-build Nasus out-scales the 1v1: 200+ physical Q stacks, Wither, and an ult that hands him armour and MR. |
Nasus wants to ignore you and stack Siphoning Strike — and early he can. You have only Null Sphere at level 1 with no escape, your Q is mana-hungry, and you have no Nether Blade sustain yet, so you lose every all-in at levels 2-3. Don't deny his stacks by force; you'll just eat a Wither-locked Q trade. Last-hit at Null Sphere's 650 against a Siphoning Strike that only reaches 255, and accept that he stacks. One thing to know: his Q is PHYSICAL, so Void Stone's 10% and your magic shield do nothing against it — your mitigation early is that 395 units of daylight, and not feeding a kill on top of the stacks.
