SPACEWelcome to my first guide. This is a guide to, in my opinion, the most strategic, powerful, and fulfilling champion: Heimerdinger, The Revered Inventor. SPACE Heimerdinger is a very strong mid lane champion who specializes in pushing lanes with his excelled crowd control, as well as being an extremely helpful part of any team fight. Heimerdinger's main source of damage is from his H-28G Evolution Turret, as well as dealing tons of damage from Hextech Micro-Rockets and CH-1 Concussion Grenade. In team fights, Heimerdinger's ultimate, UPGRADE!!! causes his H-28G Evolution Turret to shoot slowing frost shots. To avoid painful mistakes, costing your team the fight, read through this guide and learn all there is to know about what it takes to be a master with Heimerdinger. Released: 00/00/13 Roles: Mage, Pusher, Ranged Price: 3150 IP / 790 RP

Pros + Crowd control. + Can be very powerful. + Easy CS. + Useful in team fight. + He will wreck you. + Good early game. // Heimerdinger is the best person for crowd control. It is the easiest thing for Heimerdinger to pick up over 300 CS in a game. His turrets, along with his powerful rockets and grenades, make him a force to be reckoned with. If played successfully in mid lane, you can push a tower without taking a single thing of damage.

Cons - S l o w. - Moderately squishy. - Rune/Mastery dependent. - Can accidentally take buffs. - Mana hungry. - Low health value. // Heimerdinger is a very slow champion! But don't let his speed fool you! Although he's slow, Heimerdinger doesn't go down without a fight. I can't tell you how many times i've ran away and gotten a kill while my turrets have finished an enemy off. Because he's so squishy, it's important to not get too risky, and to let your turrets to most of your work.

SPACEFor masteries, I take a 9/0/21 page focusing on everything you need to keep yourself alive, collect gold, and set yourself up for victory.

Sorcerer's Shoes gives you more penetration and more speed.. AND IT'S GREAT. I'm a firm believer in boots, so I highly suggest taking these early in the game. +15 Magic Penetration +45 Movement Speed You may also want to add Enchantment: Alacrity if you find that the speed you have isn't enough.

Mejai's Soulstealer is a wonderful item you should take somewhat early in the game. Due to it's affect, it's a great item to take as you begin to rack in the kills and assists. You get the following stats. upon 20 Stacks: +20 Ability Power +160 Ability Power +15% Cooldown Reduction 1 Stack(s)/Assist 2 Stack(s)/Kill

Athene's Unholy Grail is personally one of my favorite items. It's a very well rounded item that gives you the following: +60 Ability Power +40 Magic Resist. +15 Mana Regen. +15% Cooldown Reduct. On kill or assist: +12% of mana is restored

Rabadon's Deathcap is just a bruiser item for the AP champs. Rabadon will give you a lot, and I mean A LOT of Ability Power. Rabadon will give you: +120 Ability Power +25% Ability Power This will be where a large chunk of your ability power comes from.

Void Staff is an item I feel that is essential. Void staff increases your ability power, and gives you magic penetration, letting all of that ability power go to destroying your enemy. Void Staff gives you: +70 Ability Power +35% Magic Penetration Magic penetration helps kill *****es. 'nuff said.

Deathfire Grasp is an item I normally didn't have in my build, but I've seen it's usefulness. It grants you an UNIQUE ACTIVE ability to deal 15% of the enemies total health, and makes them 20% more vulnerable to magic damage. It also gives you: +100 Ability Power +15% Cooldown Reduct.

Honorable Mentions:

---

Zhonya's Hourglass is an item I would recommend if you are getting a bit more abused than you should by AD champions. It gives some armor, which Heimerdinger doesn't really have any of. It gives you: +100 Ability Power +50 Armor UNIQUE ACTIVE: Stasis for 2.5 seconds

Abyssal Mask is an item I would recommend if you are getting abused by a champion using a lot of Ability Power, or if there are just a majority of AP champions on the other team. It grants you: +70 Ability Power +45 Magic Resistance UNIQUE AURA -20 Magic Resist to enemies

Frozen Heart is an item i would only recommend if you find yourself against an AD champion that you seem to almost kill, but die before your turrets or other abilities give you the chance to. It's a very risky buy, but it could save your butt. It gives you: +90 Armor +20 Cooldown Reduction +400 Mana Affects Enemies by: -20 Attack Speed

Let it be known that this, just like any champion, is NOT A SET IN STONE SEQUENCE!!!
The sequence in which you take your skills is all dependent on who you are facing mid lane, and what you feel will benefit you most. The most important thing you need to know is to take your H-28G Evolution Turrets FIRST ALWAYS. H-28G Evolution Turret will be your primary source of income, power, and reliability. These are your life supports. These will save your life, and get you triple kills. Although H-28G Evolution Turrets are your primary skill used during mid lane, his W and E ability as well as his R ability are all very important to utilize well also. Hextech Micro-Rockets are excellent for tight situations as well as abusing during mid lane. If running away from a champion, or catching up to a running away enemy, Hextech is a real lifesaver. Ch-1 Concussion Grenades is a useful, even more powerful skill, which also has the beneficial additions of revealing terrain and causing stun. Finally, his UPGRADE!!! makes getting a quick runaway easy. If you know the enemy is coming, you can active this power and cause your H-28G Evolution Turrets slow the enemy as it hits them.

The Evolution Turret is your primary source of damage output and is completely necessary to play Heimerdinger well. It is very important that you take this item FIRST. Heimerdinger's H-28G Evolution Turret has a few basic functions you need to know about. H-28G Evolution Turret gains new improvements on each level you improve it. Rank 1: Yellow Turret Rank 2: Green Turret - Reduces Armor and Magic Resist by 1 for two seconds every hit (up to 50 stacks) Rank 3: Green Turrets - Ability to cast 2 turrets rather than one Rank 4: Green Turrets - +125 Health Rank 5: Red Turrets - +50% Splash Damage (Damage that affects surrounding enemies) ACTIVE: Heimerdinger constructs a Turret with 260 + (15 × level) health that fires at nearby enemies, dealing magic damage (half damage to towers and inhibitors). Heimerdinger stores enough parts for a new turret every 25 seconds (affected by cooldown reduction). Turrets attack 50% faster for the first 6 seconds after placement. Turrets disappear automatically when Heimerdinger dies. Turrets receive upgrades and transform with every ability rank. TURRET RANGE: 525 TURRET ATTACK SPEED: 1.25 SIGHT RADIUS: 625 RANGE: 250 COOLDOWN: 1 (FORMS NEW TURRET EVERY 23 SECONDS) MANA: 70 / 80 / 90 / 100 / 110

The Hextech Micro-Rockets are another one of Heimerdinger's primary skills you're going to want to take early due to it's large damage output, it's range, it's ability to hit multiple enemies, and it's benefits in last-minute kill situations. ACTIVE: Heimerdinger fires 3 long range rockets that hit the enemies closest to him. RANGE: 1000 COOLDOWN: 10 MANA: 65 / 85 / 105 / 125 / 145

CH-1 Concussion Grenade

Ch-1 Concussion Grenade is Heimerdinger's real powerful, and useful move for farming cs, and for quick get-aways. Later in the game, you should be able to use the Ch-1 concussion Grenade to clear away entire mobs of CS from your lane, or if someone is chasing you, you can time it right and end up stunning them for a quick get-away. ACTIVE: Heimerdinger lobs a grenade at a targeted location, dealing magic damage to enemy units and blinding them. Enemies who are directly hit are stunned for 1.5 seconds. PROJECTILE SPEED: 750 RANGE: 925 COOLDOWN: 13 / 12 / 11 / 10 / 9 MANA: 80 / 90 / 100 / 110 / 120
