Read from Heimerdinger's seat: which stage windows this plan plays for against Zac.
This is Heimerdinger's own plan; across 149 pooled games the lane is leaning Zac.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Zac | Level 1 you have one turret and no stun, and Zac's passive blob sustain plus an E sling over the wall lets him reach you before your zone exists. |
| Level 2 | Even / skill | Your second H-28G turret and slowing beams start to contest, but Zac trades evenly behind blob pickups and soaks the poke — genuinely even. |
| Level 3 | Zac | Zac can still sling E onto you on a cooldown and knock you up on landing, punishing you before your full nest and CH-3X grenade are online. |
| Levels 4-5 | Even / skill | Three turret charges plus the CH-3X grenade let you center-stun a landed sling, but his blob sustain keeps it close — a coin-flip on whether the stun lands. |
| Level 6 | Heimerdinger | UPGRADE!!! gives you a super-turret or a wider, longer-stunning CH-3X — your one clean window to delete a committed, E-down Zac. |
| First item | Zac | His first tank item turns the sling-dive into a survivable all-in, and his blobs out-sustain your chip while you cannot heal turret damage back. |
| Two+ items | Zac | Fed Zac's E sling knocks you up and his Q pull chains the dive through the buildings onto your immobile body, and his tank stats out-rotate the nest you can't move. |
Zac is the immobile-melee profile you usually bully — except his E sling jumps a wall straight onto you before your nest is fully built, and his passive blobs heal off your H-28G turret poke faster than one cannon can chip it away. Level 1 you have a single turret and no stun, so respect an early E sling and last-hit from max range behind the cannon. Bank your H-28G charges fast: the slowing electron beams and a held CH-3X grenade are the only things that make his sling-in regret it. Do not throw the grenade early — save the center-stun for when he commits with E.

Start Doran's Ring + 2 Health Potions and back for Oblivion Orb (≈800g) — cuts his healing. Build Liandry's Torment (turret burn) first, then Rylai's Crystal Scepter, with Sorcerer's Shoes.
