Read from Jayce's seat: which stage windows this plan plays for against Heimerdinger.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jayce | You have cannon Q through the Acceleration Gate and he has a single turret with no grenade — your gated Shock Blast out-ranges his lone beam and chunks him on every step-up. |
| Level 2 | Jayce | Still no grenade and one turret: keep gate-Q poking from max range and last-hit freely while he can only eat chip and slowly bank charges. |
| Level 3 | Jayce | E online means the gated Shock Blast pops a fresh turret before its beam ramps, and the cannon-swap shred (Mercury Cannon's first hit) breaks his resists through the chip. |
| Levels 4-5 | Even / skill | His three banked turret charges plus the CH-2 centre-stun finally make a full nest a no-fly zone, so neither of you freely owns this window. |
| Level 6 | Heimerdinger | His spike, not yours — UPGRADE!!! gives the super-turret or wider stun grenade, while your R is only the stance-swap you already had, so he reclaims this level. |
| First item | Jayce | Eclipse/Manamune lets your gated Shock Blast and Hyper Charge out-poke his turret beams and rockets from outside their range and reopen the siege. |
| Two+ items | Jayce | Keep kiting the immobile yordle with stance-swap speed, poking his nest down from max range — just respect forward-placed turrets at objectives. |
You out-range his entire kit at level 1 — he has one lone turret and no grenade yet, and your cannon Q fired through the Acceleration Gate chunks him before any beam reaches you. Punish him the instant he steps up to last-hit. Once you have E at 2-3, the gated Shock Blast pops a freshly placed turret before its beam ramps to full damage, so he can never anchor a nest on the wave. Don't swap to Hammer yet; this is a pure poke war from max distance, and you win every exchange his short-range beams can't answer.
