Is Heimerdinger AP or AD Champion?

Here is the answer:

Heimerdinger is an AP champion, and all of his abilities scale with ability power. Three of his abilities are damaging, making Heimer an immobile champion that relies only on his movement speed to dodge or disengage from fights. 

He only has one main attribute meaning it is not that hard to build items on him, build AP items that either raise his ability power or build magic penetration items when enemies are stacking up on magic resist.

Best Items on Heimerdinger

  • Liandry’s Anguish – Heimerdinger’s turrets can be an annoying factor when you are laning against him. These turrets can continuously damage you when you reach their range; it deals magic damage, so it constantly procs all the effects of AP items like the DoT of Liandry’s Anguish.
  • Zhonya’s Hourglass – During fights, enemies have no choice but to dive Heimerdinger within his turrets. Chances are enemies will get stunned in the middle of the turrets and get hit by three lasers of Heim’s turrets; Heimerdinger can activate Zhonya’s to be in stasis mode while the enemy champion takes all the damage from the turrets.
  • Morellonomicon – Most AP champions that can deal continuous damage and have long-range need to have this item as a means to inflict grievous wounds on multiple enemies. Heimer can easily inflict this passive on his enemies through his turrets or upgraded spells.
  • Rylai’s Crystal Scepter – This item greatly synergizes with Heimer’s turrets; they can continuously hit an enemy with their basic attacks and slow them while the enemy is within their range. Eliminating enemies will make it easier for Heimer to hit them with his stun grenade.
  • Demonic Embrace – Combine this with Liandry’s Anguish, hit an enemy with just one spell, and watch their HP go down slowly. 
  • Rabadon’s Deathcap – This is the staple item for any poke AP champion in the game.

Best Runes on Heimerdinger

  • Conqueror – Heimerdinger is an AP champion. Still, he excels at extended fights because of his turrets, he might not be like an assassin that can deal tons of damage within one second, but he can destroy even the tankiest enemies with his turrets. Continuously damaging enemies with his turrets can easily stack Conqueror.
  • Presence of Mind – Heimerdinger is a caster champion, and having to poke an enemy in the early game messes up your mana pool, so having the bonus mana regen is a plus. Enemy takedowns also restore his mana so he can cast more of his spells.
  • Legend: Tenacity – tenacity helps him get out of sticky situations.
  • Cutdown – There are tanks which is a no-brainer to take this when you are an offensive champion.

When Should I Pick Heimerdinger?

The best time to pick Heimerdinger is if you do not have a strong frontline tank, Heimerdinger can put up a wall by planting his turrets in front of his team every time a team fight is brewing. Nobody will dare to get near his turrets as he can simply hit them with one spell, and the turrets will deal burst damage.


Heimerdinger is an AP caster mage that can hold a lane down by planting his turrets; no enemies can pass this, and he is excellent at freezing lanes. He can hold his own on extended fights as long as he has Zhonya’s Hourglass.
