How to play and combo preview

Written guide · based on the official ability texts

Heimerdinger is a turret mage: his passive gives him speed near allied or deployed turrets. H-28G Evolution Turret places a turret with a piercing laser, Hextech Micro-Rockets converge toward his cursor, CH-2 Electron Storm Grenade stuns and slows, and UPGRADE!!! boosts the effects of his next spell.

Heimerdinger's strengths

His turrets deal continuous damage and help control an area or a lane.
CH-2 Electron Storm Grenade stuns the units hit directly and slows nearby ones.
UPGRADE!!! boosts the effects of his next spell.

Heimerdinger's weaknesses

His power depends on his turrets: far from them, he is vulnerable.
Not very mobile outside his speed near turrets.
The Grenade and Micro-Rockets have long cooldowns.

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.

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.

Counters and matchups

How to play against Heimerdinger

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!
