Track: Kassadin's R — Riftwalk (5–2s cooldown). His mobility spike at 6. Kill him before it scales.
Read from Jax's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 with just Leap Strike is your weakest window, but an escape-less Kassadin is equally helpless — contest his Null Sphere last-hits and set up the level 2 spike. |
| Level 2 | Jax | W gives you Leap Strike into an Empower-charged hit — a burst a no-dash Kassadin can't trade back before you E his return auto. |
| Level 3 | Jax | The full Leap Strike + Empower + Counter Strike combo is online — dodge his auto, then stun-strike him while he has no Riftwalk out. |
| Levels 4-5 | Jax | You out-trade a pre-6 Kassadin every time — rank the combo and all-in when he walks up to farm, since he can't disengage. |
| Level 6 | Even / skill | His Riftwalk and your R land together, so the all-in is a coinflip — you win it only if you catch his blink on cooldown. |
| First item | Kassadin | Once his first AP item is up his Riftwalk cooldown drops and Null Sphere starts denying your combo — the duel begins tilting his way. |
| Two+ items | Kassadin | Full-AP Kassadin out-scales you hard: Riftwalk in, silence, Force Pulse burst — E can't touch his spells, so play safe and let your team handle him. |
Kassadin is one of the easiest melees to bully before 6 — he has no dash and his only walk-up trade is Null Sphere's silence-and-shield plus an auto, so play hard to your level 2-3 spike. Take W at 2 and punish with Leap Strike into the Empower-charged hit; at 3 the full kit is online and Counter Strike is your trump card. When he steps up to auto you, pop E to dodge that basic attack, then recast to stun and strike him while he's stuck in melee with no escape. Just know E only eats his auto — Null Sphere is a spell and goes through it — and his passive shield soaks magic, so it's your physical Leap Strike and on-hit pressure landing the work here, not raw magic ticks.
