Favour timeline — the windows in Jayce's game plan

Read from Jayce's seat: which stage windows this plan plays for against Zac.

StageFavouredWhy
Level 1JayceHe must walk up to last-hit; your free Cannon Q out-ranges Zac at level 1 and chips him before the wave even matters.
Level 2JayceUnlocking Acceleration Gate turns Shock Blast into full-range artillery — punish every step-up while he has no way to close.
Level 3JayceFull kit at 3: gate-Q poke into stance-swap Armor/MR shred bursts him each time he reaches for a passive blob.
Levels 4-5JayceThe poke war keeps tilting — Thundering Blow knocks his Elastic Slingshot engage out of the air before his Q/W CC lands.
Level 6Even / skillLet's Bounce is his one real spike — the knock-up and dive/disengage narrow your follow-up window, so level 6 is genuinely even.
First itemJayceYour Tear/Eclipse plus the stance-swap shred is your peak; force the burst before he buys Bramble/Visage to eat the orb.
Two+ itemsZacTwo items in he out-scales you — blob sustain and R bounce make him an un-burstable frontline, so the lead had to be banked early.

How to beat Zac as Jayce: the early game

Zac has to walk into the wave to last-hit and to step on his passive blobs, and that step-up is exactly what you punish — sit at max range and fire Shock Blast through Acceleration Gate the instant he commits, then position to deny the blob so his Cell Division sustain never resets. From level 2-3 the accelerated gate-Q out-ranges his entire kit, and your stance-swap (R) shreds Armor/MR on the first hit so any step-in gets chunked. The only real threat is a fog-of-war Elastic Slingshot, so hug the open lane and keep clear of walls and his jungle paths where his one gap-closer can land flat-footed.
