Hi There!
Welcome to my first guide on mobafire, I dont have much experiance with guides but im sure this will help. As you can see this is a guide for Heimerdinger, I made this guide to spread how AMAZING Heimerdinger is.

So, here goes. I hope you enjoy this guide and I hope it shows you a thing or two about Heimerdinger.

Heimerdinger is an AP Caster that generally plays in mid lane or jungle, however this guide focuses more on Mid lane Heimerdinger.

Now, Lets take a closer look at Heimerdinger...

For masteries, I like to take 21 points in Offense and 9 points in Utility.


I take all the points on the right side of the Offense Tree to give me a bonus in AP damage, such as Mental Force , Blast and Archmage

In the Utility Tree, I take points for movement speed, Neutral Buff Duration and Mana per Level, It is important that you have extended buff duration!

Guide Top


NOTE: Ignore this part if you are not level 30!

Runes are a great thing, but unfortunatly they dont get good until you have reached the cap level. The Tier 1 Runes provide So much less than the Tier 3 Runes. Here is what runes i like to take for Heimerdinger


Greater Mark of Magic Penetration

Greater Seal of Scaling Mana Regeneration

Greater Glyph of Magic Resist

Greater Quintessence of Ability Power
    I take Magic Pen. marks, for breaking through enemy defense.
    I take Mana Regen. Seals, because
Heimerdinger is Very mana hungry
    I take Magic Resist Glyphs because usually, the enemy mid will also be a caster.
    I take Ability Power Quintessences for that extra bit of early AP power.

Passive - Techmaturgical Repair Bots - Nearby Turrets and Allies enjoy increased Health Regeneration.

Heimerdinger Lays down a machine gun turret. Turrets gain abilities as this skill is increased (Turrets deal 1/2 damage to towers.)
This ability is just fantastic, the evolution turret deals alot of damage to minions, making it a great farming tool, however champions can take it out easily when they are with their minions.

Heimerdinger fires long-range rockets that hit the enimies closest to Heimerdinger.
This is a nice ability, it deals moderate damage to 3 enimies closest to Heimerdinger, This is great in jungle team fights.

Heimerdinger lobs a grenade at a target location, dealing damage and stunning enimies directly hit and blind surrounding enimies.
Again, another great ability. It deals high damage and if you get a direct hit you stun the enimies/enemy and blinds enimies on the out-skirts of the blast! Wow!

Passive - Increases cooldown reduction. Active - Activate to heal all nearby evolution turrets and cause them to fire frost shots, which reduce enimies movement speeds
This is an amazing ability in 1v1 combat. Open with a concussion grenade for the stun then place 2 turrets nearby, activate UPGRADE!!! for the frost shots and your target will not escape.

Summoner Spells

Viable Summoner Spells

Ignite - Ignite is great for all casters, i strongly recommend you dont skip over this one!

Flash - This spell is great for Heimerdinger, as he does not have any escape methods.

Clarity - It's ok taking this spell for Heimerdinger, But if you don't spam too hard mana problems can be avoided. It has a very reasonable cool down.

Semi-Viable Summoner Spells

Ghost - This is OK, but not really a spell or an AP caster, take it if you have no other options.

Heal - I suppose this is an OK spell. Very handy indeed.

Exhaust - You dont really need it at all, but if you dont have any other options take it.

Teleport - Quite a handy spell to have, It lets you get around the map quickly. If you are under level 12, take this instead of Flash

Non-Viable Summoner Spells

Surge - Hmm... OK... Where do i start? This summoner spell is awful, on any champion. Espesically not an AP Caster. This Summoner Spell Has Now Been Removed

Promote - What are doing, dont pick that one! You are not a tank, you dont need this. This Summoner Spell Has Now Been Removed

Clairvoyance - Not this one either, You arnt a support. Dont take it.

Revive - The aim of the game is not to die, But seriously its a waste of a summoner spell.

Cleanse - I guess this is ok, but i am right in saying this is a non-variable summoner spell for an AP caster.

Starter Items

In 5v5 I like to start off with an Amplifying Tome and 1 Health Potion

The next time you go back try and have about 1.8k gold, Then upgrade the Amplifying Tome to a Kage's lucky pick and pick up a pair of Sorcerer's Shoes and a Chalice of Harmony
Next you want to start building for a Rod of Ages, buying a Catalyst the Protector first.

Mid-Game Items

Now that you have Rod of Ages, build for a Rabadon's Deathcap. This will give you amazing ability power.

From here upgrade Chalice of Harmony to Athene's Unholy Grail.

Late-Game Items

Next, start to build for Zhonya's Hourglass and buy Elixir of Brilliance for the AP boost.

Ok so im going to sum up everyting i've just said in the guide. Here are a few key points.

    Remember to ask a jungler for blue, as you are quite mana hungry
Rabadon's Deathcap Is a MUST!
Always strat off with an Amplifying Tome
Place turrets in your lane to farm minons easily and quickly
You do exceptional damage to squishy targets ( Ashe, Annie)
You are quite squishy if focused!
Take either: Flash, Ignite or Clarity
Mana regen runes!
I consider Heimerdinger as the very best mid-laner
