Favour timeline — the windows in Heimerdinger's game plan

Read from Heimerdinger's seat: which stage windows this plan plays for against Ornn.

This is Heimerdinger's own plan; across 551 pooled games the lane is leaning Ornn.

StageFavouredWhy
Level 1Even / skillYou concede the level-1 contact window with one turret and no stun, but so does Ornn — his E dash and Brittle aren't online either, so it's a wash.
Level 2HeimerdingerSecond turret plus the slowing beams turn the lane into your zone — Ornn's only step-up is an E dash that walks straight into them.
Level 3HeimerdingerWith the CH-3X grenade you punish any dash-in: center-stun Ornn as he commits and three charges win the trade.
Levels 4-5HeimerdingerYour full nest plus center-stun makes every Ornn all-in suicidal — his Brittle combo can't out-DPS three turrets while he's CC'd.
Level 6OrnnOrnn's R magma elemental plus its recast ram is a chained double-knockup that locks the immobile yordle long enough to die to him or a gank.
First itemEven / skillLiandry's into Rylai's keeps the siege honest, but he buys tank stats faster than you buy penetration — it is a coinflip.
Two+ itemsOrnnFull-tank Ornn shrugs the turret economy, forges upgrades for his team, and R-initiates through your static nest — he out-scales the front-loaded lane.

How to beat Ornn as Heimerdinger: the early game

Ornn can't out-trade your turrets once they're up — his only early step-ups are the E dash-knockup and a W Brittle proc, both of which force him into beam range. At Level 1 you have one turret and no stun, so don't fight over CS; just bank the charge while he uses W to push and shield. The moment you have a second turret and the CH-3X grenade, you start zoning: bait his E dash, sidestep so it doesn't slam you into terrain, then drop the center-stun on him as he overextends into the nest.
