Read from Swain's seat: which stage windows this plan plays for against Kassadin.
This is Swain's own plan; across 133 pooled games the lane is leaning Swain.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Swain | Kassadin at Level 1 has no mobility and a magic shield that only blocks magic damage — W his farm path and Q-burst for free poke he cannot return. |
| Level 2 | Swain | Null Sphere shields him against your magic damage, so break the shield with Q bolts first, then E-root on the return sweep and pull the Soul Fragment. |
| Level 3 | Even / skill | Both of you have full kits now but his Riftwalk is still on a long cooldown at low ranks — fishing for an E-root into pull is still viable if you bait the Q first. |
| Levels 4-5 | Kassadin | Riftwalk is up and stacks efficiently; he blinks out of your E mid-flight, so your root combo becomes unreliable and he can disengage your R drain at will. |
| Level 6 | Kassadin | Riftwalk is 5s at rank 1 and every repeat cast costs him more mana — poke with W, collect cs, and commit only with a CC chain from your jungler behind it. |
| First item | Kassadin | Seraph's or Shadowflame spike means his Q shield absorbs your W+Q burst; your trade pattern relies on converting the root into burst damage that no longer exists at this power level. |
| Two+ items | Kassadin | Full Kassadin shrugs off your magic damage with Void Stone, Riftwalks out of drain range every 2s at rank 3, and bursts you before Demonic Ascension banks enough fragments — respect the curve and play grouped. |
Kassadin is genuinely one of the weakest Level 1s in the game — his passive magic shield only triggers on magic damage and his Q silence is short range, so walk up, land a W on his farm path, and Q-burst him when it hits. At Level 2 your E comes up and he still has no mobility: step up, throw W on his likely position, and the moment the eye lands E-root him into a pull — every fragment you collect here is permanent max HP he cannot take back. He will try to Q-silence you to dodge the E followup, so throw E first, THEN Q so the bolt burst hits a rooted target. Don't burn E on minions; every miss is a death sentence when he hits 6.
