Hello everyone, this is LEmon Elephants and I have worked very hard to prepare my very first guide for my favorite champion Heimerdinger. Heimerdinger has always been very underplayed which made those of us who did play him have a special feeling in our hearts whenever we laid eyes upon our brainiac friend. A very versatile champion, Heimerdinger is a very fun and viable pick for all sorts of play styles ranging from support to aggressive AP mid. With interesting turret mechanics and a 3 sided ultimate, you never know what trick the Revered Inventor might pull out of his sleeve.

Like it, tell me why!
Have a problem? Feel free to down vote but please let me know how I can improve my guide.
Thank You

This section is for the beginners to league of legends. If you stick to the game a little longer you will know these terms like the back of your hand but to help you get on your way here is.....


  • ace= all of the enemy team is dead for the moment. Beware spawn times but now is an excellent time to push.
  • aoe = area of effect, an ability which covers an area, rather than a single character.
  • AP = Ability Power. The stat which boosts the effectiveness of abilities.
  • aura = A 'passive' which applies not only to the hero who has it, but also to heroes within the given range for the aura. A shareable passive.
  • bd/backdoor= To attack the enemies towers and base without the cover of your creeps there
  • brush = The large grass in LoL which causes your hero to be hidden to people outside of the brush
  • buff = Typically a temporary increase to some stat(s)
  • carry = A character who, if played properly, wins late game fights for a team. Typically these heroes are weak early game and require a lot of farming.
  • CC = crowd control. Moves that interfere with the other champions actions such as stun, fear, knockbacks/ups and blind.
  • CD= Cool down, the time between using abilities.
  • champion = The particular character that you as the summoner control
  • dd = direct damage ability. Typically DDs are unavoidable: Click ability, click target, profit. For example: Annie's Q fireball.
  • Disable = A Disable is a debuff that usually prevents some kind of action on the player. Stuns, roots, silences are all examples of disables
  • DOT = Damage over time.
  • dps = Damage per second. Also referes to characters who job it is to deal damage (As opposed to support and tanks)
  • executed= killed by a tower with no enemy hero receiving credit for it
  • Farm = Farming involves the amassing of gold for player. This is usually best done by killing a lot of creeps and killing them very quickly. Certain Heroes like Ashe and Tristana are great farmers: The first has a +gold passive, and the latter has an AOE passive.
  • feed = A player who dies constantly feeds the other team (via the gold reward for killing someone). Being called a feeder is not a compliment. A player who is fed has a lot of kills.
  • grass = see brush
  • harass - to annoy the enemy with small bursts of non lethal damage, often forcing them to go heal or be set up for a gank.
  • hero = non-canon name for a champion
  • humiliation= killed by a creep with no enemy hero receiving credit for it
  • IAS= Increased Attack Speed
  • juke, juking = When being chased, juking is to fool your pursuers. Typically this happens in the jungle. A successful juke could range from eluding the enemy by exploiting line of sight, or could simply cause the enemy to mistarget a spell.
  • jungle = to attack neutral creeps, allowing for 2 solo lanes and better ganking.
  • lane = the road like expanses that contain towers and lead to and from the bases

  • ms = movement speed
  • neutrals = The creep-enemies who live in the jungle
  • neuts = neutrals
  • passive = An ability which is not activated but helps a character. For example, Morgana's passive allows her to heal a small % of the damage her spells inflict. Passives usually apply only to the hero who has them.
  • pbaoe = point blank area of affect. The area of effect is centered around the caster such as Nunu's Ultimate or any aura. (not widely used)
  • Proc = refers to a weapon, item or ability activating with the "Chance on Hit" or "Chance on Use" effect (an ability or a spell). "Programmed Random OCcurence"
  • Root = A debuff which prevents any movement by a champion (summoner spells excluded)
  • Silence = A debuff which prevents any abilities being used by a champion (summoner spells excluded)
  • skillshot = an ability that fires a projectile that can be dodged. For example: Morgana's cage, Ashe's ultimate arrow
  • Snowball = an item that grows with kills, that can quickly become very dangerous unless kept in checked by death.
  • Stun = A debuff which prevents any action by a champion (summoner spells excluded)
  • summoner = Your representation in the game. Essentially you are the puppet master of your selected Champion and you have your own summoner abilities along with the champion's abilities.

  • tp - summoner spell teleport used to traverse the map "I'll tp back in"
  • ult = ultimate ability. The R Ability.
  • unique = In LoL certain auras/passive are unique, meaning they do not stack.
  • top, mid, bottom = the lanes in LoL.

  • jungle = The mass of trees and paths that exist between the lane
  • gg = good game.
  • gj = good job.
  • gl hf - good luck, have fun, usually an encouraging sportsmanlike phrase said before a game,
  • disc, dc = disconnect from a game.
  • b = back, fall back, they're coming for you
  • back = fall back, they're coming for you
  • bait - to deliberately appear in a position to be easily ganged so as to lure 1 or more players to be gangked by your team "go bait them in to the jungle"
  • base, basing = going back to base
  • bp,pill, pilling = blue pilling, going back to base
  • care = be careful, they may be coming for you

  • DD (alternative)= don't die. Also sometimes direct damage
  • focus = To target a player. Meaning that as a team you all will all focus on a specified hero to kill first.
  • gank - to go (often with more than one player) to try and kill an enemy, often by surprise "lets gank bottom" . An Ambush

  • Kite= to draw a hero away from a comfort zone such as tower or allies and into a gank, creepwave, or other painful situation
  • lom = low on mana
  • miss, mia = Missing, missing in action. Commonly used to describe when a hero is missing from a lane and may indicate to the team that a gank may happen.
  • oom = out of mana
  • pot = potion (sometimes elixirs too)
  • push - to gather up a creep wave and attempt to destroy an enemy tower "I'm going to push bottom"
  • QQ = meaning to tell some one to quit, often as a rage quit. Coincidentally depicts a set of crying eyes and has also come to mean "cry more"
  • raqequit = To quit a game in anger (Being killed, losing)
  • shop,buy = To go back to base to go shopping, can mean you should shop or they are shopping

    (This is not really my dictionary but I like to call it that. I found it here on the LoL forum. Many thanks to Larias a forumn Adjudicator that threw this together!)

Lore and Skin Recommendation


Below is Heimerdingers's lore, this is straight from Riot, let's thank them for their great game and thoughtful creativity.
It is unusual to see yordles outside of Bandle City, but the lure of science was something Heimerdinger could not resist. By the time he'd completed his third doctorate, he had already become the greatest of all yordle scientists and there was little his home could still offer him. The great academies of Piltover far to the north called to him, daring him to make his mark in the City of Progress. Knowing he would never thrive away from his own kind, Heimerdinger gathered like-minded yordles to join him in his quest, thus forming the backbone of the now famous Yordle Academy of Science & Progress. Since then, he has become one of the most respected minds of the modern age and his academy is one of the leading institutions in all of Valoran.

Heimerdinger has pioneered many new scientific achievements, delving deeper and deeper into the field of techmaturgy, including the development of the now ubiquitous star-rods that light many of the streets of the city-states. However, there is something strange about the Revered Inventor. In his quest to expand knowledge, he underwent an experiment of his own design to allow him to use a greater portion of his brain simultaneously. It most certainly worked, but at an unusual cost - Heimerdinger's brain increased in size. His head changed along with it and now the great scientist looks like a yordle with a giant brain-shaped head. Heimerdinger has turned his attentions to the current state of war on Valoran, however, and works to rectify what he considers is an unacceptable situation. Heimerdinger believes that science is the key to saving the world. Much more, he has rolled up his sleeves and is out to prove this as a member of the League of Legends - most definitely as the League's smartest champion!

Science is on the march. Look out!

Runes are an essential aspect to League of Legends for any champion. Luckily these runes are almost always completely up to us and we may change them to what we prefer. I am in no way telling you that these are must haves, merely the runes I recommend.













Greater Quintessences of Ability Power- These runes are fantastic on many AP mid laners. Whether you have burst, or sustained damage these will help boost up the damage through the scaling that all of Heimerdinger's abilities boast.

Greater Quintessence of Scaling Ability Powere- An alternative option to boost your magic damage. this is very similar to quintessences of AP however these provide less AP in the beginning and more later on. Great if you are building late game heimy.

Greater Quintessence of Health- Another helpful option, great for strategy of baiting opponents under your turrets followed by a quick stun. Heimerdinger is a very squishy champion and this can help negate some of the problems that arrive as a side effect.

Greater Quintessences of Movement Speed- Very useful options to help you get to and from lane faster and to move around for positioning those pesky missiles.


Greater Glyph Of Magic Resistance- Very powerful and versatile runes, these can be used for almost any build and are particularly effective on mid champions as a majority of the opponents you will face will be doing primarily magic damage.

Greater Glyphs of Mana regeneration- Very useful for a champion like Heimerdinger who burns through mana so fast. I recommend these over glyphs of scaling mana regeneration because you only really need this extra mana early game.

Greater Glyphs of Cooldown Reduction- Very expensive and not my favorite for Heimerdinger. For 820 IP a pop they will require lots of IP grinding that is most likely better spent on cheaper runes.


Greater Marks of Magic Penetration- Most likely the best option for Heimerdinger. This early game magic penetration paired with sorcerers boots helps a lot to support Heimerdinger's new found bursting potential. These are the only marks I truly recommend.

Greater marks of Scaling ability power are the only other marks I like for Heimerdinger. Pick these if enemy team is obviously not very tanky and you feel the late game ability power will be more helpful than magic penetration, though this is rarely the case.


Greater Seals of Gold are my personal favorite runes. Seals are where Heimerdinger's flexibility of roles shows in runes and this is a prime example. Many people feel these are a waste but to do a little bit of math, 9 of these seals paired with an early game kage's lucky pick will give you roughly 1958 gold by the end of a 45 minute game!!!

Greater Seals of Armor are fantastic. They are very inexpensive and give you a great bonus to early game armor when facing pesky AD mid laners like Talon and Zed.

Greater seals of Scaling Armor revolve around the same principle as seals of armor. Choose these when enemy team has strong late game physical damage or if you want to add these to a "Laterdinger" style build.


The idea behind Heimerdinger's runes are that they will adapt to your playstyle feel free to choose what fits you best but try to remember this and think about what I said. This will help you draw your own conclusions about what runes might fit Heimerdinger best and let you compare your thoughts to mine.

Summoner's wrath is a very effective mastery, especially when you roll exhaust and ignite which is my personal preference.

Sorcery is very good for Heimerdinger as he has some relatively long cooldowns and this CDR is very nice for its cost in masteries.

Butcher is very helpful when you are last hitting, as 4 bonus damage can make quite a big difference when last hitting. Not essential it only makes your life easier early game but if you have mastered last hitting with Heimerdinger feel free to put points in something else.

Blast is very helpful, 18 ability power at level 18 for 4 points is most effective way to get ability power in masteries. If building full damage it is the only way to go.

Havoc is a great damage boosting mastery on all champions. I recommend taking 2-3 points in this as the percent bonus scaled very well with your turrets basic attacks.

Arcane knowledge is, in my opinion, the best mastery in the offense tree. 8% magic penetration is absolutely sentential for Heimerdinger.

Meditation is great, almost always get 3 points in this. Fantastic mana regen on such a mana reliant champion.

Improved Recall- You need 1 more point to advance up the utility tree and I recommend putting it here. Much more useful for putting 1 point in than your other option.

Mastermind will help you a lot as you will be very reliant on your summoner spells for early game kills and as such I recommend putting 3 points in it.

Expanded mind is not a must but the mana boost is quite nice.

Greed is great. Earlier I talked about how with an early kage's lucky pick and 9 gold seals will give you about 2k gold at the end of a 45 minute game. With 4 points in this and the other Gold/10 items you will receive 2498 gold by the end of a 45 minute game! I highly recommend getting 4 points in this especially when playing supportdinger or against a counter mid.

Runic Affinity is highly recommended because blue is sooooo great on Heimerdinger. This will largely increase the time you hold blue buff making it possible to have blue buff on at almost all times.

Most likely my favorite mastery, strength of spirit works extremely well with any caster you stack mana on. When you get Seraph's Embrace you will have 2410 mana without masteries and runes. This means that you will gain 18 health regeneration per 5 seconds by the end of the game. Adding this to your passive you will heal roughly 10 health per second which can make a gigantic difference in many ways.

Heimerdinger constructs a turret at the target location. Heimerdinger stores the parts for a new turret every 24/23/22/21/20 seconds and can keep 1/1/2/2/3 in reserve. The storage time is affected by cooldown reduction.

H-28G Evolution Turret Stats:
Health: 150 (+25 per champion level)
Attack - Cannon: 15/22/29/36/42 (+12.5% of ability power) magic damage
Attack - Beam: 50/75/100/125/150 (+50% of ability power) magic damage in a line, 12 second cooldown (affected by Cooldown Reduction)
Heimerdinger can have up to 3 turrets constructed at a time.
Turrets go offline if Heimerdinger is more than 1000 units away for longer than 8 seconds.

This is a phenomenal ability if played well. Often very difficult to line up this move effectively this move often separates good Heimerdingers from the bad ones. Try to master using this move efficiently in teamfights!
Heimerdinger unleashes a barrage of 5 rockets that converge on the target location and fan beyond it up to a maximum range, each rocket dealing 60 / 90 / 120 / 150 / 180 (+45% of ability power) magic damage to the first enemy it hits.
Enemy champions and neutral monsters that are hit by more than one rocket take 20% magic damage for each rocket beyond the first, up to a maximum of 108 / 162 / 216 / 270 / 324 (+81% of ability power). Enemy minions take 36 / 54 / 72 / 90 / 108 (+45% of ability power) damage from each rocket.

Very good ability post-rework. Much more difficult to hit but has so many uses. As you are able to change the angle of the shots it can go from a borderline OP single target poke to a fantastic farming and teamfight ability.
