Role in team fights

Heimerdinger turns a corridor or an objective into a defended zone: turrets placed in advance, the Electron Storm Grenade to stun, Micro-Rockets for range. UPGRADE!!! on the right ability often decides the fight.

Common mistakes

• Fighting far from your turrets.
• Casting the upgrade with no clear spell to boost.
• Placing turrets with no protection.

Cooldowns, costs and ranges

A combo only comes back once its abilities are off cooldown: these values (rank 1 to max rank, in seconds) tell how long to wait between two combos. Source: Data Dragon 16.19.1.

Riot's official tips for playing Heimerdinger

• Turret placement can be a deciding factor in a battle. Against most enemies turrets are best when they can support each other, but if the enemy has a lot of area of effect damage your turrets can be destroyed quickly. Placing turrets in brush can lead to a surprise attack in your favor.
• The success of Electron Storm Grenade is very important to Heimerdinger's survival. The slow and stun both are capable of keeping enemies in place long enough to punish them, but it is also the first line of defense against a surprise attack.
• Spreading out Hextech Micro-Rockets leads to more reliable damage and more efficiency against multiple targets, but focusing it creates the biggest impact.

How to play around Heimerdinger's combos

• It's better to destroy all of Heimerdinger's turrets at once with the help of creeps than to fight them one at a time.
• Be wary of Heimerdinger's Upgrade!!!, as he can use it to find an answer to most trouble he gets into. Once his ultimate is down, go in for the kill!
