Read from Trundle's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Trundle | The Null Sphere shield only absorbs magic damage, so Chomp lands in full from level 1, and King's Tribute tops you back up off every dying minion. |
| Level 2 | Trundle | With W placed and two levels of stats you out-damage his poke; E Pillar along the wall turns any trade into a kill attempt he cannot walk away from. |
| Level 3 | Even / skill | His R is still locked out and your full Q+W+E kit is online, but Null Sphere interrupts channels and Force Pulse cones a slow onto you — the window is real, just not free. |
| Levels 4-5 | Kassadin | Level 4-5 Kassadin starts rushing tear and sitting on waveclear; your Frozen Domain only helps if he walks into it, and he is smart enough not to — the lane advantage begins slipping. |
| Level 6 | Kassadin | R blink comes online and the matchup flips: he teleports through your Pillar, escapes Frozen Domain, and controls every trade distance — Subjugate alone cannot hold this window. |
| First item | Kassadin | Iceborn Gauntlet gives you a small durability bump, but Kassadin's Shadowflame lets him burst and blink before your W healing matters — the gap widens. |
| Two+ items | Kassadin | At two items Kassadin's R cooldown is effectively zero in a sustained skirmish; he blinks through every Pillar, erases you with AP burst, and your Subjugate drain cannot close the damage gap. |
Pre-6 Kassadin is genuinely weak — Null Sphere is a 9-second cooldown that interrupts channels rather than silencing, and the shield it leaves behind absorbs magic damage only, so your physical Chomp goes straight through it. Walk up with W already placed, bite him on every step-up, and use Pillar to cut his retreat along the wall. King's Tribute heals off every wave death, so his poke is close to irrelevant near minions. Look for a real kill at level 3 if he lets you run him into a Pillar inside Frozen Domain — that is your cleanest window before his game-changer arrives.
