i'm still writing this build and figuring out some issues so the guide won't be complete yet

Hi guys its the explosive heimer this is my first guide so don't be too mad at me if I muck it up. I'm no professional so please feel free if you want to give me a tip to help improve this guide.

I will be using some phrases in this build. Skip this chapter if you know the in game phrases already.
ap=ability power
ad=attack damage
mr=magic resist
cdr=cooldown reduction
adc=atttack damage carry
apc=ability power carry

Heimerdinger is a ranged caster with many pros and cons. Here is a list of them.
PROS

• Has amazing burst damage
• has an aoe stun/slow
• good wave clearing and amazing pushing with his turrets
• has fairly good sustain with his passive
• farm's easily
  CONS
  
  • very very squishy
  • no natural escape options
  • he has a weird, weird afro
  • vulnerable to ganks

Many people think of heimerdinger a a troll pick when they see him. Heck if you play him in ranked or normal you will be flamed alot. But you should always try out new things don't be stuck to the meta. Try out things that people never thought of. BREAK THE METAAA:)

I pick these runes as my standard runes but there are some other runes you may want to consider if you are facing different mid laners...

• you may want this if you are going against an ap mid with burst damage
• the best for ad mids
• dunno i feel the ap from the non scaling quints help you more from early-mid but whatever you like
• the rest is up to you according on what you would like to changebut try to keep change minimal and only change the quints if possible
  If you are not lv 21 and above yet DON'T but any tier 1/2 runes cus they r a waste of ip

helps you to stay in lane for al longer period of time ,its like a mini aegis
You want to max your q first as its your main damage tool and it can help the jungler and yourself to farm in the laning phase.try to always put all 3 turrets down and don't use em for wards, you should use your trinkets instead. I will cover the places you should ward in where to ward.if the opponent has a blink like leblanc or talon try to stay within your turrets to dissuade them as they will probably kill themselves. try to put 1-2 turrets down to help your jungler before heading to lane to set down some turrets. By the way, if the opposing team has a blizcrank, you may want to set 3 turrets in a cone formation to protect the buff.
ahh this skill, the burst potential on this skill is insane, you can deal so much damage especially when you ulti this skill. I take a point in this skill to harass your opponent in the laning ph***e.be sure to land these as they have crazy range and damage. Their only down size is that they are really hard to hit.
CH-1 ELECTRON STORM GRENADE this skill is an aoe stun/slow it is really potent when it hits but is the most difficult skill on heimerdinger to land.try to ulti this skill and hit the entire enemy team with this in a teamfight.
this basically gives your other skills a massive boost. Putting down an ulti'ed q or e can change the course of an entire teamfight while an ultied w can allow you to easily busrst someone to death

x2 Fairly straightforward and standard start for any ap casters. Grabbing the doran's ring for the mana as heimerdinger is fairly mana hungry and the health pots for even more sustain in lane. I take the warding totem to get a free ward. Always try to remember which buff the enemy jungler starts with and look at the second one that he has not taken. If he tries to gank it will be from that side.
I then pick up boots and a chalice as heimer is mana hungry and the extra movement speed will help him alot. If you can try to pick up a ward or two along with some health pots, then use your remaining gold to start building towards athene's. The CDR, extra AP and mana regen is awesome on heimdinger. If the opponent is an ad caster get a seeker's armguard then build anthene's. Get a sorc shoes. Upon completing your sorc shoes, get a needlessly large rod and build it towards a zonya's hourglasszonya's hourglass. Being the squishy guy he is, heimdinger needs that survivability to dish out the heavy damagehe is capable of. especially useful for screwing up combo reliant champions like malzahar or heavy burst from someone like zed's death mark.
Then its time for the almightyradabon's deathcap. If everyone has been laughing at you for ages for having "the least contribution" then prove them wrong and show them heimerdinger is not a champion to laugh at. By now if you are snowballing then feel free to grab a mejai's. I personally dislike this item as i find it unreliable and you can fall behind and not get back up. If you are not careful. I would personally recommend either a deathfire or a lich bane. Finsish with a Gaurdian angelGA or any item from the list below.
