When Is Heimerdinger Strongest?
The win rate tops out around the two-item spike, then levels off, and games at this rank average around 28 minutes. Heimerdinger wins by turning a defended position into a no-go zone, so use the power window to lock down an objective or choke point and make the enemy fight through his turrets on his terms.
Heimerdinger Item Build
Heimerdinger is a zone-control specialist who fights from behind a wall of turrets rather than trading in the open. The build leans on ability power, mana, and haste so his cannons hit hard, his grenade lands the pick, and he keeps the whole kit online in extended sieges.
Best Heimerdinger Runes
Conqueror leads the runes here, and it plays into his constant chip damage. Between turret beams, rockets, and grenades, Heimerdinger is always dealing a little damage to something, so a keystone that rewards steady output beats one built for a single burst. Fill out the rest for the mana and survivability a poke-and-zone style needs to keep casting.

Heimerdinger Skill Order
By 16 the last UPGRADE!!! rank arrives into a kit that is already settled: the H-28 G Evolution Turret finished at 9 and Hextech Micro-Rockets at 13, leaving CH-2 Electron Storm Grenade to soak up 14, 15, 17 and 18.
Heimerdinger Abilities
UPGRADE!!! is the piece the turret talk skips, readying an enhancement for his next spell that turns a grenade or a volley of Hextech Micro-Rockets into something far bigger. His passive, Hextech Affinity, grants move speed near allied towers and his own turrets.
Heimerdinger Base Stats
Heimerdinger Matchups
Heimerdinger walls out short-range attackers and dive threats who cannot break his turret line without eating a full stun rotation. He has a harder time against long-range pokers and roaming assassins who ignore his setup and force him off the turrets he depends on.
