Read from Jayce's seat: which stage windows this plan plays for against Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jayce | He has to walk into melee range of his casters to farm and his Null Sphere shield is thin early — free gate-Q Shock Blast poke at Levels 1-3. |
| Level 2 | Jayce | Cannon form out-ranges Kassadin's whole kit, and the Mercury Cannon-to-Hammer swap shreds his MR on the first hit every time he steps up to last-hit. |
| Level 3 | Jayce | Acceleration Gate turns Shock Blast into full-range, full-damage poke and the swap-shred stacks on top — this is Jayce's hardest early-favour window before 6. |
| Levels 4-5 | Even / skill | Roughly even mid-lane: you still out-poke him, but he's hoarding XP behind casters waiting on Level 6, so the lead is yours to press or lose. |
| Level 6 | Kassadin | Riftwalk at 6 blinks him out of To the Skies! and the 20s Thundering Blow — at rank 1 it is 5s, so he still only gets one escape per trade. |
| First item | Kassadin | His first MR item plus the passive magic-reduction shield cut your Shock Blast poke, and he hits his own item spike while you're still squishy. |
| Two+ items | Kassadin | He hard-outscales: a two-item Riftwalk Kassadin double-blinks onto your no-defense frame, bursts you, and kites every gap-close — group and let your team handle him. |
Kassadin is one of the weakest melee laners into a Cannon-form caster — he has to walk into Shock Blast range to last-hit and cannot answer it, so abuse that. Fire the orb THROUGH Acceleration Gate for full range and damage, then if he steps up swap Mercury Cannon into Mercury Hammer — the first hit shreds his armour AND his MR. His Null Sphere shield only absorbs magic damage, so it does nothing to the physical orb; it does not silence either. Trade on its 9s cooldown and he has no answer at all.
