My name is Professor Cecil also know as Professor Heimy, and I bring to you my Cheese Strategy of how to get to Level 2/3/4/5/6 faster than the enemy laner and what exactly you can do with those level advantages.

Keep in mind all level advantages presented here past level 3 last more or less 30 seconds, so do plays around those.

I started playing Heimerdinger since near end of Season 2 when I got invited to the game by a University friend at around October of 2012 and first Champion I actually played when I started was Ahri surprisingly when she was at Free Week not much after I found the Turret Master and never gave up on him.

Season 3, I ended Nrº 1 Heimerdinger Eu-W, Nrº3 World and Nrº1 Performance wise on Champion before rework with 59% Win Rate, got near Diamond elo however after Heimerdinger got reworked I ended quitting and not long after I had no time to dedicate to the game due to work reasons.

My Heimerdinger stats on Season 3:


Season 5, I ended Top 300 Heimerdinger World with 66% Win Rate, ended Platinum 4 with around 90 games and decayed to Gold 1 with 75 Lp´s due to inactivity, ended having to quit due to family illness problems and not long after work reasons as well.

My Heimerdinger stats on Season 5:

Season 8 and with now available time, I am currently top 20´s on Heimerdinger and 7th Ranked Heimerdinger on Eu-W.

Champion ranks will vary depending on my scores, etc so they are in a constant upgrade. :p

At the start I had some issues with not having available the Old Raptor Camp Strategy, however, with some patience, I found a creative way to rework it.

With this guide, I bring you both the normal Heimerdinger as well an Reworked version of the Old Raptor Camp, where you get early Gold Advantage and Level Advantage if played properly you should have the Upper Hand early game which is a big game changer of how Mid and Late Game can progress.

Pros + Ranged Poke + Brush reveal + AoE CC and AoE Slow + Great Objective Control + High Burst + Strong late-game Heimerdinger is a control mage that excels at team fights. While he does feel reliant on H-28G Evolution Turret since he does not have an in-built escape there are many times you can bait the enemy into your H-28G Evolution Turret and stun them with CH-2 Electron Storm Grenade. Heimerdinger has a solution for most possible events on his kit making him a very versatile champion.

Cons - Hard to recover when behind - Susceptible to CC - Hard to Master - Requires to plan ahead - Junglers don't want to gank your lane - People might flame you Heimerdinger sadly is not all roses, he has many strengths but he also has a couple of weaknesses. Overusing your H-28G Evolution Turret can lead you to die, not positioning them properly as well makes you more vulnerable. Jungler barely gives you blue buffs and your team might not know how to play around you, your team might also expect you to be able to push Towers super fast early game and that is not how it works, as your H-28G Evolution Turret are not that strong to deal with that aspect so soon.

	FLASH: Heimerdinger standard Summoner Spell, it can be used both offensively and defensively, you can check below for all the offensive type of plays you can do as Heimerdinger with Flash.
	SMITE: Heimerdinger bread and butter for what this Guide offers, on how to be an filthy Smite abuser on Heimerdinger , plus it offers you the real combos to aim for without going for the 8.10 Patch Scuttle Crab Fiesta.
	TELEPORT: Heimerdinger is a Champion that excels quite well with Teleport, it allows for coming back to your lane, or go for a Teleport gank on one of the enemy laners or to help your Jungler contest some objective.
	IGNITE: Heimerdinger with Ignite is more aggressive than Heimerdinger with Teleport, however as the Elo progresses and the laner knows how to play against Heimerdinger in general this Summoner Spell value decreases.
	CLEANSE: Heimerdinger with Cleanse is not your usual Champion Select final Summoner Spell pick, as Heimerdinger two of the Champions I would highly consider taking this Summoner Spell against would be Zoe and Fiddlesticks or against an extremely heavy Crowd Control enemy team composition, also take into consideration Cleanse counters Ignite damage, however it does not remove the healing reduction debuff from Ignite.
	HEAL: Heimerdinger with Heal combination makes it a fairly strong Summoner Spell for Heimerdinger, that can give you an advantage on 1 vs 2 fights on level 6 duels, as it can make you survive and still get a tasty double kill with your UPGRADE!!! + H-28Q Apex Turret, however take into account late game most heals can be countered by Morellonomicon or Executioner's Calling.
	GHOST: Heimerdinger with Ghost like it is not bad of a Summoner Spell however I would not take it personally, unless you want to cheese even further Movement Speed + homestart buff + Celerity for the Jungle Camp for even higher H-28G Evolution Turret damage, other than that I believe the other Summoner Spells are far more useful.
	BARRIER: Heimerdinger with Barrier is great against Champions that can instantly burst you, like Syndra, Zed, LeBlanc for example, plus it ignores two ticks of the Ignite, plus it can also be used offensively the same way as Heal for 1 vs 2 situations with UPGRADE!!! + H-28Q Apex Turret at early levels.
	EXHAUST: Heimerdinger with Exhaust is also a great option if you are facing a strong all in Champion to the point it denies nearly almost the entirety of his burst, champions like Zed and Talon are one of the few matchups you might want to take Exhaust.

	Sorcery: Heimerdinger and for most general builds Sorcery is the least confuse rune to aim for. Sorcery offers you the best, Offensive Runes, Defensive Runes, and Utility Runes.

	Summon Aery: Heimerdinger and Summon Aery for pretty much half of Season 8 has been a match made in Heaven itself, his H-28G Evolution Turret will proc it, all your skills proc it as well, and there is no cooldown, and in matter of fact the closer you are to the enemy the faster you can proc Summon Aery again, due to the return of Aery to your Champion. Summon Aery is 100% hit rate and despite not having the best Ability Power Ratio Scaling, it is an effective and brutal aggressive way of poking over and over the enemy Mid Laner since Heimerdinger got a great Auto Attack animation.

	Nullifying Orb: Nullifying Orb is one of the options you have as a secondary rune on Sorcery, it gives you a certain safety against multiple Ability Power threats on enemy team or if you are dealing with a Champion that can easily burst you down. Remember a dead Heimerdinger does no damage but one that is alive sure is annoying to deal with. Every 60 seconds Nullifying Orb recharges and whenever it gets activated it only lasts 4 seconds. A level 18 and full build Heimerdinger usually gets around 170-240 Magic Damage Shield when you take damage that would get you below 30% HP, depending on how many Infernal Dragons your team got, if your team got Elder Dragon or Baron Nashor or if you have Elixir of Sorcery up.

	Manaflow Band: Manaflow Band is one of the options you have as a secondary rune on Sorcery, it gives you more mana pool and gives some freedom if you buy Luden's Tempest as first item and you do not get Blue Buff or if you buy Archangel's Staff it gives you more Ability Power and Extra Shield. Manaflow Band is not as efficient as it used to be after it got changed on Patch 8.7, despite that, there are many matchups that you can use it on as Heimerdinger, one example is Anivia. Manaflow Band passive when stacked restores 1% of your missing mana every 5 seconds, which let's be honest is not that great. I would say that to get the 10 stacks of Manaflow Band as Heimerdinger it usually takes around 7 to 10 minutes into the game in a normal scenario. Also take into consideration H-28G Evolution Turret beam also procs Manaflow Band. This rune is now more viable with the addition of Nimbus Cloak to the 2nd Row of Runes on Sorcery as well the fact it replaced The Ultimate Hat being this last one on the Domination Rune renamed as Ultimate Hunter.

	Celerity: Heimerdinger and Celerity is the bread and butter of the Smite strategy which is also provided on this guide if you are interested. Movement speed bonus that leads to your initial turrets doing more damage and with this you can clear a Jungle Camp without much trouble. Laning phase, wise your passive Hextech Affinity, further makes Celerity stronger and it buffs up your entire kit especially your H-28G Evolution Turret. Celerity is also good without going for the Smite strategy provided on this Guide. Celerity + Homestart Buff boosts your Ability Power greatly since you nearly reach 700 movement speed for the duration of the buff. You can take advantage of this early boost in between Inner Tower (Tier 1 Tower) and Outer Tower (Tier 2 Tower). If you feel your Jungler is getting invaded you can help secure one of the Jungle sides. Celerity + Hextech Affinity gives you an Ability Power boost when you are near your H-28G Evolution Turret or when you are near your own team Towers, it gives you early 6 Ability Power and can be increased with all of the items below. Best Items for Heimerdinger that can boost your movement speed are: Boots: Boots Ionian Boots of Lucidity Mobility Boots Boots of Swiftness Mercury's Treads Ninja Tabi Sorcerer's Shoes Active Items: Shurelya's Battlesong Spellbinder Flat % Movement Speed Items: Aether Wisp Shurelya's Battlesong Twin Shadows Spellbinder Champion Skills that buff Heimerdinger movement speed are: Bard and his Caretaker's Shrine; Janna and her passive Tailwind; Jayce and his Acceleration Gate; Karma and her Inspire or the empowered version Mantra Bonus - Defiance; Kayle and her Divine Blessing; Kled and his Chaaaaaaaarge!!!; Lulu and her Whimsy; Mordekaiser and his Harvesters of Sorrow; Nami and her Ebb and Flow, Tidecaller's Blessing due to her passive Surging Tides; Nunu & Willump and his Call of the Freljord; Orianna and her Command: Dissonance; Sona and her Song of Celerity; Zilean and his Time Warp; Buffs for Heimerdinger that can buff your movement speed are: Your Passive Hextech Affinity; Cloud Drakes and Dragon Slayer: Stratus Walk and if out of combat the movement speed from the bonus is tripled; Elder Drake which initially increases the value of the other Drake buffs by 50% and any Elder Drake afterward increases everything by 100%;

	Absolute Focus: Absolute Focus is one of the possible routes you have as substitute to Celerity, it gives you Ability Power per Champion Level and you get to keep this bonus as long you have above 70% Health Points. Absolute Focus is a good option if you need Ability Power and need to rush defensive items. Absolute Focus synergizes the best with Taste of Blood and Ravenous Hunter and if you do well you should be able to upkeep 60-90% of the time Absolute Focus.

	Gathering Storm: Gathering Storm is one of the possible routes you have as last rune on Sorcery, it gives you Ability Power every 10 minutes and the longer the game goes the more Ability Power you get. Gathering Storm is great vs all champions, however, you will see the most benefits against Juggernauts, as it might require you to go with Magic Penetration and an HP Burning Build. Sorcerer's Shoes or Ionian Boots of Lucidity Luden's Tempest or Archangel's Staff Liandry's Torment Morellonomicon Rabadon's Deathcap Void Staff Is usually the type of build you might have to go vs High HP and Resistances enemies. Morellonomicon, Liandry's Torment and Void Staff tend to be the rushed items. So having that extra Ability Power over time removes some of the pressure of having to purchase Rabadon's Deathcap as it costs 3600 Gold.

	Scorch: Scorch is one of the possible routes you have as last rune on Sorcery, one of your skills does extra damage as a burn on enemy. I feel that Scorch is mostly an early game extra damage tool, rather than mid and late game, if you take this I would say to take it against some of the Low Wave Clear Champions at level 1/2/3 as there is the possibility you either kill them or remove them from lane if they overextended at level 1. Scorch is also semi-countered by Bone Plating so take that into consideration when you take this Rune. As many Supports or Marksman take Bone Plating especially if they are against a Matchup that can poke them a lot.

	Domination: Domination is a great burst Rune Page that you might want to take as Heimerdinger. As Heimerdinger, Domination offers you the best sustain runes for either laning phase or for doing solo objectives if such is needed, with the addition of a burst rune.

	Taste of Blood: Electrocute is your burst keystone from the Domination rune page and the best keystone it offers to Heimerdinger on the Domination tree. Heimerdinger has a ton of burst from his kit alone but if you add Electrocute you have the surprise factor when it comes to dealing damage to the enemy without them suspecting. Despite the Electrocute early levels damage nerf, the cooldown got cut by half making it possible to proc it from 1 up to 2 times per minion wave in the best case scenario.

	Taste of Blood: Taste of Blood is your sustain rune from the Domination page. Heimerdinger takes a ton of advantage with Taste of Blood compared to Cheap Shot. Taste of Blood is a heal that scales with your Ability Power and that every 20 seconds whenever you Auto Attack someone or do a skill it heals you, despite not being much every time, after a while it is several Health Potion that you end not buying. Taste of Blood relieves some of the damage you might have taken before, during or after a trade with the enemy. A full build Heimerdinger can get from 110 up to 170 heal from Taste of Blood. Despite Taste of Blood not having the best Ability Power Ratio Scaling, it is a nuisance to deal with if an enemy is playing against you.

	Cheap Shot: Cheap Shot is one of the possible routes you have as rune on Domination, one of your skills does extra damage as True Damage as long it impairs enemy movement and the cooldown is fairly low. Cheap Shot is up to you, I do not dislike the extra damage, however CH-2 Electron Storm Grenade is on a fairly long cooldown and I can imagine people forcing themselves over and over to use CH-2 Electron Storm Grenade just to get the extra damage which can lead you to die or waste mana too much. Late game 40 true damage is neglectable and I feel there are better options out there. I would only advise getting this rune as an exception if you are rushing Rylai's Crystal Scepter as skills will proc the True Damage effect and even still you have to be careful and do proper mana management as Rylai's Crystal Scepter rush means high likely you have to rush Morellonomicon second due to the enemy champion kit.

	Eyeball Collection: Eyeball Collection is your go happy where you farm kills or wards for extra Ability Power on Domination Rune Page. Eyeball Collection is a decent substitute and if you want to go for the most possible Ability Power than get Gathering Storm on Sorcery. If you take Eyeball Collection you will be replacing Taste of Blood and not Ravenous Hunter. I would consider this Rune if you have a Jungler like Jarvan IV or Shaco to give wings to the absurd amount of cheese the Smite Strategy can offer you.

	Ravenous Hunter: Ravenous Hunter is one of the options you have as an Rune on Domination and what I take 100% of the time, you will embrace it everyday. H-28G Evolution Turret and Ravenous Hunter is a match made in heaven. H-28G Evolution Turret auto attacks count as a single target entity when it comes to Ravenous Hunter and "Oh, boy!", you recover so much HP back. You get a Flat 2.5% Damage to Heal Ratio without any stacks and at 5 out of 5 stacks you get 15% Damage to Heal Ratio, and this is when Heimerdinger pops off when it comes solo objectives such as Baron Nashor and it also makes you so much harder to kill on Team Fights.

	Ingenious Hunter: Ingenious Hunter is one of the options you have as an last Rune on Domination. - Have many active items? - Enemy team has some assassins that can one-shot you? If the answer to both is yes, Ingenious Hunter might be the Rune for you. With 5 out of 5 stacks we are looking into 40% less cooldown on all the active items in-game. Zhonya's Hourglass, Seraph's Embrace, Hextech Rocketbelt, Spellbinder, Twin Shadows, Shurelya's Battlesong and Quicksilver Sash as Heimerdinger you can consider those. However, remember that it can be quite tricky to not take Ravenous Hunter on some matchups but it depends on your Playstyle obviously.

	Ultimate Hunter: Ultimate Hunter is one of the options you have as an last Rune on Domination, unfortunately this Rune no longer is existent on the Sorcery Rune Page as it was previously named The Ultimate Hat and has been moved into Domination, however it is still fairly strong. If you tend to roam most of the time than you can consider it especially if you are running an Ability Power build without much Cooldown Reduction.

	Inspiration: Inspiration is the most Utilitary Rune Page that you can take as Heimerdinger. As Heimerdinger, Inspiration is usually taken as an Secondary Rune Page to either get Perfect Timing for more defense along with the possibility to do a double immunity with Stopwatch and Zhonya's Hourglass or Minion Dematerializer for more wave clear and lane priority.

	Unsealed Spellbook: Unsealed Spellbook is your go too keystone from the Inspiration Rune Page and the only that matters as Heimerdinger. Heimerdinger is great with any Summoner Spell, so what if you could use any of them? Unsealed Spellbook makes this possible and for any Summoner Spell that you swap to your next Summoner Spell, further swaps have 20 seconds less cooldown.

	Magical Footwear: Magical Footwear is one of the Contraption Runes that you can select on the Inspiration Rune Page. Heimerdinger has an base 340 Movement Speed and at an early game he tends to buy Boots which cost 300 Gold, but this rune, gives you Boots free of cost at the 10 minute mark while giving you 35 Movement Speed instead of 25 Movement Speed. Movement Speed will always offer you a lot of repositioning potential for the most diverse cases. Every takedown being it from kill or assist makes you get the empowered boots 30 seconds sooner.

	Perfect Timing: Perfect Timing is one of the Contraption Runes that you can select on the Inspiration Rune Page. Perfect Timing is the defensive rune that gives you a free Stopwatch that can be used at the 10-minute mark. This rune suffered quite a lot of nerfs going from 6-minute mark to 8-minute mark than going into 10-minute mark into once again 8-minute mark and afterward 10-minute mark. It is hard to balance this rune since immunity to all forms of damage from either Stopwatch or Zhonya's Hourglass are both really strong items that can be used in a ton of ways. Perfect Timing also reduces the active cooldown on Zhonya's Hourglass by 15% which is really strong on Heimerdinger and his ability kit.

	Future's Market: Future's Market is one of the Tomorrow Runes that you can select on the Inspiration Rune Page. Future's Market is as if you had a bank loan with interest on it. Gives you the opportunity to rush an item much faster giving you quicker aggressivity or defensive value on a lane at the expense of losing gold to interest. If you do not take Minion Dematerializer I would consider taking this rune, since Inspiration secondary means you will have less damage, therefore, rushing Ability Power makes it important and mandatory.

	Minion Dematerializer: Minion Dematerializer is one of the Tomorrow Runes that you can select on the Inspiration Rune Page. Minion Dematerializer is a good rune option if you want to further be annoying and push waves faster especially on Cannon Minion waves. Minion Dematerializer one shots the minion that was clicked by you, either Melee Minions, Caster Minions or Cannon Minions, take into consideration it does not work against Siege Minions. It also gives you an increased % damage to the Minions you hit with either Auto Attacks or Abilities. Minion Dematerializer helps you get some lane priority which is always important for both you and your Jungler aside from the fact you do not need to spend resources to kill a minion be it either time, mana or health points.

	Cosmic Insight: Cosmic Insight is one of the Beyond Runes that you can select on the Inspiration Rune Page. Cosmic Insight is perhaps the strongest if not the best Rune in the entire game for multi-purpose cases. It lowers all the Summoner Spell Cooldowns, active items can be used a lot faster, it increases the maximum Cooldown Reduction cap from 40% to 45% and it gives you free 5% Cooldown Reduction. If you go Inspiration as a secondary or even primary rune page, always take Cosmic Insight it is extremely strong.

	Hextech Affinity: Heimerdinger passive grants you 20% Movement Speed as long you are on 300 Range from your H-28G Evolution Turret, Towers or your H-28Q Apex Turret.

This passive is mostly focused on Utility and you can squeeze the most of it against Melee Champions with no Gap Close skills, being one example Nasus.

In my personal opinion, despite giving movement speed under the parameters mentioned above, this passive binds Heimerdinger into a weird spot that might feel over-reliant on his H-28G Evolution Turret especially against High Wave Clear Champions, being a good example to the extreme Aurelion Sol himself as the only way to keep up is building Cooldown Reduction.

Item Builds with Cooldown Reduction increase the value of Heimerdinger passive.

I usually tend to buy Lost Chapter into Fiendish Codex as it gives 20% CDR, 75 Ability Power 300 Mana and 20% of your Maximum Mana Restored whenever you Level Up.

This build costs 2200 Gold and is the most cost efficient for everything Heimerdinger requires against most matchups on Mid Lane.

If you do go against something on Top Lane extremely tanky or that likes to take HP recovery items, you can consider buying 2 or 3 Doran's Ring into Void Staff and from here either get a Morellonomicon or a Zhonya's Hourglass.

	H-28G Evolution Turret: Heimerdinger builds a mini turret at the location you select on your Cursor, and every 20 seconds you get 1x H-28G Evolution Turret and mini turret recharge time can be lowered by Cooldown Reduction Items.

Heimerdinger and his H-28G Evolution Turret is what he most know for, whenever Heimerdinger appears everyone knows about his Turrets, they can be used Offensively, Defensively, they can Block most of the skillshots ingame and are also a great zoning tool.

Heimerdinger is a champion that requires good game knowledge to not feed as well Champion boundaries so you do not overextend beyond your limits as it can lead to the enemy laner to snowball due to how Heimerdinger kit works.

H-28G Evolution Turret plays a part in this.

For starters, you will want to practice the last hitting while H-28G Evolution Turret is also hitting Creeps.

Also, make sure you do not target 2 Creeps at the same time as there is a high chance you lose both.

Aside from that, you will want to know where the enemy jungler starts and know what Champion the enemy jungler is playing.

Champions with heavy high single target damage that are likely to gank or invade after first buff, like Lee Sin, Udyr, Jarvan IV, Shaco, Camille, Xin Zhao, Olaf are great examples of excellent dueling Champions at level 2.

You will want to be even more careful against those as when they are well played they can force your Flash and you can turn into a walking stick leading you to death.

Laning phase, placing all the 3x H-28G Evolution Turret on your lane not long after when you can leave base is perhaps the worst thing to do, at most you will only place 1x H-28G Evolution Turret and work around from there and whenever you have another available charge, you will place it so you are not capped.

Against Champions with Area of Damage skills, or skillshots with a long distance mostly on a line, you need to adapt so that 2x H-28G Evolution Turret are not in range for the enemy to kill both, the only Champion you will find near impossible to execute this macro play is Aurelion Sol due to his Astral Flight as the skill itself when is activated nearly occupies the entirety of the lane.

Plus during laning phase if possible always place your H-28G Evolution Turret on the opposite side your Jungler is as it can close the gap between your Jungler and the enemy laner and in case you cannot place both on the opposite side, at least place the one that is on your Jungler side a bit back so that the enemy laner feels more comfortable being on that side and that you can make the enemy have a fake safety so that your Jungler can have an easier time.

Going into Ability Power and Heimerdinger and his H-28G Evolution Turret, your H-28G Evolution Turret do not automatically change their damage according to the items you buy as their damage is based accordingly to the Ability Power or H-28G Evolution Turret rank, at the time you used them.

A bulletproof way to understand this is, for example, having a full build with let's say 700 Ability Power, you place 3x H-28G Evolution Turret anywhere in the map, you go to base and sell everything and come back to your Turrets, you will notice that the H-28G Evolution Turret damage is still the same from when you had 700 Ability Power even although currently after selling every item you have let's say 60 Ability Power.

So whenever possible when you come back to lane with more Ability Power try to replace your existing H-28G Evolution Turret if there is any, so that they do more damage and are more bulky with any Ability Power and Skill Rank Up you get on them.

Also when playing Heimerdinger and if the macro play allows it, you place "X" amount of H-28G Evolution Turret and make sure you always have 1 Charge of H-28G Evolution Turret spare, aside from very few circumstances.

So let's assume you got a kill on the lane, recalled to base and enemy Jungler went to mid cleared wave and destroyed all your 3x H-28G Evolution Turret which at the time being were Inactive due to you not being near them.

You have now 3x Charges of H-28G Evolution Turret and just got back to lane, you place 1x H-28G Evolution Turret defensively and 1x H-28G Evolution Turret in an aggressive position, and save the last Charge if required, until you have 2x Charges of H-28G Evolution Turret and than you use the other one so you have 3x H-28G Evolution Turret on lane and 1x H-28G Evolution Turret for replacement if needed to.

Also Heimerdinger has a trick specific utilization which relies on Auto Attacking as the beginner setup to execute it.

You use CH-2 Electron Storm Grenade and place 1x H-28G Evolution Turret while CH-2 Electron Storm Grenade is mid air.

Be aware that it is a high-risk strategy just to ensure that the H-28G Evolution Turret Beam hits the target since the H-28G Evolution Turret as the further the elo goes, people will exploit the fact that you used your only CC Skill for both offensive/defensive purposes.

In a macro play small guide, there are only 3 times you use the CH-2 Electron Storm Grenade + H-28G Evolution Turret combo mid-air and 3 times only:

- Whenever you have less than 3x H-28G Evolution Turret on lane optimally 2x H-28G Evolution Turret so you can have 3 Beams hit the target if you hit the Stun

- Whenever enemy Jungler was spotted in another lane or passed by a ward recently and you are not capped on H-28G Evolution Turret on the lane

- Whenever enemy Jungler was spotted in another lane or passed by a ward recently if you intend to use a Charge of H-28G Evolution Turret when you are already capped on H-28G Evolution Turret on the lane

The last one is to replace the defensive H-28G Evolution Turret into an aggressive position.

This is the most important thing when playing Heimerdinger since CH-2 Electron Storm Grenade is both your Engage and Disengage Tool.

If I do this I will tend to do it whenever I have 2x H-28G Evolution Turret on lane cast CH-2 Electron Storm Grenade while it is mid-air place 1x H-28G Evolution Turret wait for half second and then use Hextech Micro-Rockets like this the enemy is hit with 6 Beams and it is the most the safe combo with less key inputs.

If you hit the CH-2 Electron Storm Grenade on the enemy, instead of Hextech Micro-Rockets, use the UPGRADE!!! + Hextech Rocket Swarm the likelihood to 100 to 0 enemy is extremely high if they are playing an extremely squishy champion, 6 Beams + 3x H-28G Evolution Turret Auto Attacks, 2x Summon Aery and UPGRADE!!! + Hextech Rocket Swarm usually kills the enemy, if you feel Summon Aery won't be enough you can always play with Electrocute and the result should be a kill as long those parameters match.

	Hextech Micro-Rockets: Heimerdinger fires 5 individual rockets. Each rocket that hits a Champion any H-28G Evolution Turret gets 20% Turret Beam Charge up to 100% Turret Beam Charge if you hit all 5 of them.

Item Builds with Cooldown Reduction increase the value of Heimerdinger passive as well providing him with enough tools to give him possible lane priority.

When poking an enemy champion try to open up the Hextech Micro-Rockets radius so that at least one rocket hits the enemy.

You can also try and take advantage of enemy laner minions being low health points to sneak in more damage from Hextech Micro-Rockets.

Null-Magic Mantle can also be purchased too, later on, complete into one of those items: Negatron Cloak Chalice of Harmony Aegis of the Legion Mercury's Treads Spectre's Cowl Quicksilver Sash Hexdrinker Athene's Unholy Grail Mikael's Blessing Locket of the Iron Solari Zeke's Convergence Wit's End Gargoyle Stoneplate Circlet of the Iron Solari from Ornn with his Living Forge Zz'Rot Portal Spirit Visage Adaptive Helm Abyssal Mask Banshee's Veil Maw of Malmortius Mercurial Scimitar Infernal Mask from Ornn with his Living Forge You can consider buying Null-Magic Mantle if you are one of the following Champions: All Champions in League of Legends

	Negatron Cloak: Not many Champions take advantage of Negatron Cloak as first item, Season 8 removed alot of potential from this item as first buy. Negatron Cloak is usually the second buy for people who buy Abyssal Mask as the first complete item. Negatron Cloak can also be purchased too, later on, complete into one of those items: Wit's End Gargoyle Stoneplate Zz'Rot Portal Abyssal Mask You can consider buying Negatron Cloak if you are one of the following Champions: AD or AP Juggernauts AD or AP Bruisers Some Attack Speed Hybrid Champions for Wit's End

	Mercury's Treads: Heimerdinger in general got great Crowd Control with his CH-2 Electron Storm Grenade or his Empowered Version CH-3X Lightning Grenade. Pretty much the item to buy if you are a Juggernaut, Assassin, Mage or a Marksman, looking to survive into Heimerdinger stun combo. You can consider buying Mercury's Treads if you are one of the following Champions: All Champions in League of Legends

	Spectre's Cowl: Spectre's Cowl, should always be the your first item choice vs Heimerdinger if you are playing a Juggernaut type of champion. It boosts you Health Points Regen by 150% whenever you take damage for 10 seconds. Spectre's Cowl is best used along with Doran's Shield and Second Wind. Nevertheless Spectre's Cowl is an all in one sustain item that gives you Flat Health Points and Magic Resist. Take into consideration that Spectre's Cowl effects can be lowered by the following: Katarina and her ultimate Death Lotus Varus and his Hail of Arrows Executioner's Calling Mortal Reminder Morellonomicon Bramble Vest if you Auto Attack the enemy Thornmail if you Auto Attack the enemy Ignite Spectre's Cowl can also be purchased too, later on, complete into one of those items: Spirit Visage Adaptive Helm You can consider buying Spectre's Cowl if you are one of the following Champions: AD or AP Juggernauts AD or AP Bruiser in case an off-tank is required

	Hexdrinker: Hexdrinker, should always be your first item choice vs Heimerdinger or multiple AP threats if you are playing an AD Assassin or Bruiser type of champion with some exceptions taking advantage of Tiamat as early rush item. It grants you a shield that negates 110 up to 280 Magic Damage depending on your level when you are below 30% of Health Points. Normally you should be able to get this item around 5 up to 8 minutes into the game considering you are on either Top Lane or Mid Lane, therefore you should get a shield that denies around 160 up to 200 Magic Damage at this point. If you are playing Jungler I would definitely say past 14 minutes it's doable to purchase, therefore you should get a shield that denies around 200 up to 220 Magic Damage at this point. Hexdrinker makes you resistant enough when you have to go as a Melee AD into the H-28G Evolution Turret zone alongside his H-28Q Apex Turret when Heimerdinger aim is to use the CH-2 Electron Storm Grenade combo. Hexdrinker can also be purchased too, later on, complete into the following item: Maw of Malmortius You can consider buying Hexdrinker if you are one of the following Champions: All AD Bruisers All AD Assassins Akali as an exception due to her Hybrid Kit.

	Quicksilver Sash: Quicksilver Sash is an out of Crowd Control trump card with a 90 seconds cooldown. Heimerdinger has great Crowd Control with his regular stun CH-2 Electron Storm Grenade or his empowered grenade version CH-3X Lightning Grenade. Quicksilver Sash is also good against extremely heavy CC enemy team compositions, however despite all that it no longer removes the Death Mark from Zed as it used too back in Season 6. Quicksilver Sash can also be purchased too, later on, complete into one of those items: Mercurial Scimitar You can consider buying Quicksilver Sash if you are one of the following Champions: AD Marksman AP Mage AD Bruiser Active from Quicksilver Sash base cooldown is 90 seconds and only works on self.

	Mikael's Crucible: Mikael's Blessing is an out of Crowd Control trump card that can be used on one ally teammate with a 120 seconds cooldown and if successful on removing the CC it gives that ally 40% movement speed for 2 seconds. Mikael's Blessing tends to be used by a Utility Jungler or AD or AP Support on AD Marksman's or AP Mages. Heimerdinger has great Crowd Control with his regular stun CH-2 Electron Storm Grenade or his empowered grenade version CH-3X Lightning Grenade. Mikael's Blessing does not work against Suppression skills such as Malzahar with his Nether Grasp, Warwick with his Infinite Duress and lastly Skarner with his Impale.

	Locket of the Iron Solari: Locket of the Iron Solari active is really strong against all sources of damage aside from Pyke and his Death from Below and Urgot and his Fear Beyond Death as long the enemy health bar is below the one-shot threshold mechanic. Locket of the Iron Solari offers an AoE Shield to your entire team if they are close to the caster of the item active. Heimerdinger and his empowered grenade version CH-3X Lightning Grenade damage is reduced to at least half in most case scenarios as long you or your teammate utilizes Locket of the Iron Solari active properly. And the more Health Points the item active caster has the more shield it grants to your team. You can consider buying Locket of the Iron Solari if you are one of the following Champions: AD or AP Support AD or AP Juggernaut Utility Jungler Active from Locket of the Iron Solari base cooldown is 120 seconds and is only usable on Champions.

	Gargoyle Stoneplate: Gargoyle Stoneplate passive is really good against Heimerdinger since Heimerdinger is a Control Mage, and tends to be near the team squishies so you are guaranteed to proc Gargoyle Stoneplate, 3 enemy targets passive which in return provides you with a stronger Active benefit. Gargoyle Stoneplate makes you extremely harder to kill due too how much Health Points you get on active, however, remember you also deal less damage temporarily. You can consider buying Gargoyle Stoneplate if you are one of the following Champions: AD or AP Support AD or AP Juggernaut Utility Jungler Active from Gargoyle Stoneplate base cooldown is 90 seconds and only works on self. Below you can find the cooldowns for the Active from Gargoyle Stoneplate with the Runes System.

	Circlet of the Iron Solari: Circlet of the Iron Solari active is really strong against all sources of damage aside from Pyke and his Death from Below and Urgot and his Fear Beyond Death as long the enemy health bar is below the one-shot threshold mechanic. Circlet of the Iron Solari is the Masterwork Upgrade that Ornn offers you for an additional 500 Gold for an additional 15 Armor and 15 Magic Resist compared to the Locket of the Iron Solari. Remember that it requires Ornn to be level 13 before you can purchase this Upgrade and the limit of Masterwork Upgrades you can buy is only one. Circlet of the Iron Solari offers an AoE Shield to your entire team if they are close to the caster of the item active. Heimerdinger and his empowered grenade version CH-3X Lightning Grenade damage is reduced to at least half in most case scenarios as long you or your teammate utilizes Circlet of the Iron Solari active properly.

	Spirit Visage: Heimerdinger is semi countered by Spirit Visage to a certain extent. Spirit Visage is your answer if you are a Melee Champion that relies on skills that recover your Health such as Nasus or Illaoi for example, being the only exceptions Fiddlesticks, Swain and Vladimir as they are Ranged Champions. This item helps you endure to an extent the harass Heimerdinger keeps doing to you. Take into consideration that Spirit Visage effects can be lowered by the following: Katarina and her ultimate Death Lotus Varus and his Hail of Arrows Executioner's Calling Mortal Reminder Morellonomicon Bramble Vest if you Auto Attack the enemy Thornmail if you Auto Attack the enemy Ignite You can consider buying Spirit Visage if you are one of the following Champions: Aatrox Camille Cho'Gath Darius Dr. Mundo Fiora Fiddlesticks Garen Gangplank Gragas Illaoi Irelia Maokai Nasus Olaf Renekton Rengar Swain Singed Trundle Vladimir Volibear Warwick Xin Zhao Yorick Zac

	Adaptive Helm: Heimerdinger is highly countered by this item, especially on his damage from H-28G Evolution Turret. In a standard scenario, Heimerdinger can only get 1 combo against you with Adaptive Helm, and at this point Heimerdinger, either poked you properly and his gonna kill you with his stun combo. Which is still extremely hard and unlikely to happen at an early or mid game stage 1vs1, or you do not have enough damage to kill Heimerdinger and both escape alive, and you should still have a positive trade. You can consider buying Adaptive Helm if you are one of the following Champions: AD or AP Juggernauts AD or AP Bruiser in case an off-tank is required

	Abyssal Mask: Heimerdinger haves an hard time by Champions that use this item. It gets near impossible to Heimerdinger properly itemize into wave clear, defense nullification and sustain if you buy this. If you are an AP Tank or a Hybrid between physical and magical damage dealing skills and your facing Heimerdinger or multiple AP threats, after you purchased initially Catalyst of Aeons than complete afterward Abyssal Mask. Take into consideration that Abyssal Mask effects can be lowered by the following: Katarina and her ultimate Death Lotus Varus and his Hail of Arrows Executioner's Calling Mortal Reminder Morellonomicon Bramble Vest if you Auto Attack the enemy Thornmail if you Auto Attack the enemy Ignite You can consider buying Abyssal Mask if you are one of the following Champions: Amumu Cho'Gath Diana Elise Leona Galio Gragas Malphite Maokai Nautilus Ornn Swain Sejuani Singed Sion Champions that I did not list above but that still can take advantage of Abyssal Mask are Fiddlesticks, Fizz, Lissandra however not as the first buy, but more of a mid-game into a late-game purchase. Also be aware that Abyssal Mask extra damage debuff range got lowered so the Champions here are the only ones that can squeeze the most potential from the item itself taking into factor they are Melee Champions that have gap closers to get into the enemy, being the only exception Fiddlesticks, Lissandra and Swain.

	Banshee's Veil: Heimerdinger can't burst you down easily if you have Banshee's Veil. However, do take into consideration most Heimerdinger players do buy Luden's Tempest which can remove the spell shield a lot easier than you might imagine due to Luden's Tempest passive effect. Banshee's Veil spell shield cooldown is 40 seconds and it's not affected by Cooldown nor Ingenious Hunter as this rune only works for Active Items Cooldown Reduction. Also, try to get the habit of pinging the Banshee's Veil cooldown whenever it's down. You can consider buying Banshee's Veil if you are one of the following Champions: AP Mages AP Juggernauts Hybrid Marksman's

	Maw of Malmortius: Heimerdinger can't burst you down easily if you have Maw of Malmortius. Maw of Malmortius is the upgrade coming from Hexdrinker that offers a flat 350 magic damage reduction whenever you are to get below 30% of your HP, which lasts 5 seconds and has a cooldown of 90 seconds. When under the effect mentioned above Maw of Malmortius also grants you 20 Attack Damage, 10% Lifesteal and 10% Spellvamp until your out of combat, which the effect can be kept and refreshed as long you attack any target be it either Champion, Minions or Monsters.

Mercurial Scimitar is the upgrade coming from Quicksilver Sash that aside from the CC removal it also offers you a 50% Movement Speed boost that lasts 1 second. Mercurial Scimitar buying point is the 50% Movement Speed that allows you to reposition either more Offensively or Defensively. Take into consideration that Mercurial Scimitar lifesteal effect can be lowered by the following: Katarina and her ultimate Death Lotus Varus and his Hail of Arrows Executioner's Calling Mortal Reminder Morellonomicon Bramble Vest if you Auto Attack the enemy Thornmail if you Auto Attack the enemy Ignite You can consider buying Mercurial Scimitar if you are one of the following Champions: AD Bruisers AD Assassins AD Marksman's AP Mages if required but more at late-game last item Active from Mercurial Scimitar base cooldown is 90 seconds and only works on self.

	Infernal Mask: Heimerdinger haves an hard time by Champions that use this item. It gets near impossible to Heimerdinger properly itemize into wave clear, defense nullification and sustain if you buy this. If you are an AP Tank or a Hybrid between physical and magical damage dealing skills and your facing Heimerdinger or multiple AP threats, and you already have Abyssal Mask and you have an Ornn on your team consider buying the Masterwork Upgrade, for 1000 Gold more you get 200 Health Points and 35 Magic Resist more. Take into consideration that Infernal Mask effects can be lowered by the following: Katarina and her ultimate Death Lotus Varus and his Hail of Arrows Executioner's Calling Mortal Reminder Morellonomicon Bramble Vest if you Auto Attack the enemy Thornmail if you Auto Attack the enemy Ignite You can consider buying Infernal Mask if you are one of the following Champions: Amumu Cho'Gath Diana Elise Leona Galio Gragas Malphite Maokai Nautilus Ornn Swain Sejuani Singed Sion Champions that I did not list above but that still can take advantage of Infernal Mask are Fiddlesticks, Fizz, Lissandra however not as the first buy, but more of a mid-game into a late-game purchase. Also be aware that Infernal Mask extra damage debuff range got lowered so the Champions here are the only ones that can squeeze the most potential from the item itself taking into factor they are Melee Champions that have gap closers to get into the enemy, being the only exception Fiddlesticks, Lissandra and Swain.
