Heimerdinger

Mage

The eccentric Professor Cecil B. Heimerdinger is one of the most innovative and esteemed inventors the world has ever known.

Strengths

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.

Passive · Hextech Affinity — Gain Move Speed while near allied towers and turrets deployed by Heimerdinger.
Q · H-28 G Evolution Turret — Heimerdinger lays down a rapid-fire cannon turret equipped with a secondary pass-through beam attack (turrets deal half damage to towers).
W · Hextech Micro-Rockets — Heimerdinger fires long-range rockets that converge on his cursor.
E · CH-2 Electron Storm Grenade — Heimerdinger lobs a grenade at a location, dealing damage to enemy units, as well as stunning anyone directly hit and slowing surrounding units.
Ultimate · UPGRADE!!! — Heimerdinger invents an upgrade, causing his next spell to have increased effects.

A suggested 5-lane lineup built around Heimerdinger, based on hero partnerships and role synergy — not win rate.
