One of the most esteemed inventors Piltover has ever seen, Heimerdinger is one of the most versatile champions in League of Legends. Players can take him into any lane and find success with the Yordle. The champion excels against melee-based champions due to the turrets that are part of his kit, allowing him to set up a perimeter that can be used for many uses.
Runes
Sorcery
Arcane Comet: As Heimerdinger’s playstyle relies heavily on the use of his turrets, taking the Arcane Comet rune is a no-brainer.
Manaflow Band: Heimerdinger’s biggest issue, especially early in the game, comes from the lack of mana the champion has. Manaflow Band will increase the champion’s maximum mana for every ability that hits an enemy champion.
Transcendence: As an ability-based champion, Heimerdinger could potentially run into trouble in a dueling situation if his abilities remain on cooldown.
Scorch: Heimerdinger’s turrets will begin to deal impressive damage thanks to the pairings of runes and that is just made stronger with Scorch.
Inspiration
Perfect Timing: A rune that is perfect for Heimerdinger, Perfect Timing grants the champion a Commencing Stopwatch at the start of the game. At 14 minutes, the item will transform into a Perfectly Timed Stopwatch.
Cosmic Insight: This rune will grant Heimerdinger an all-round cooldown reduction on both his abilities, item cooldowns, and summoner spell cooldown.
Bonuses: +9 adaptive force, +9 adaptive force, +6 armor
Starting items
Doran’s Ring
A very common starting item for AP champions, Doran’s Ring will grant Heimerdinger some early bonus ability power, increasing the damage dealt from all his abilities including his turrets.
Health Potion
In the early stages of the game, Heimerdinger is going to be vulnerable since he doesn’t have a lot of base health to rely on for durability.
Core items
Luden’s Echo
With many AP champions, it is wise to build some items that grant durability or speed before building damage-based items. But for Heimerdinger, it pays to invest in damage early.
Luden’s Echo is a great item for Heimerdinger due to the three stats that the item will increase. The item will grant 90 ability power, 600 mana, and 10-percent cooldown reduction.
Zhonya’s Hourglass
Again, another item that perfectly fits the core of Heimerdinger’s playstyle, Zhonya’s Hourglass is a perfect item to get early on this champion. The item boasts stat increases of 75 ability power, 45 Armor, and 10-percent cooldown reduction. While these are fantastic for Heimerdinger, where the item truly shines is through its active ability.
