Hello Summoners! I first want to thank you for reading my guide, this is my first guide ever written so tips and such would be great, hope you will like it!

Pros:
+ Insanely good jungling due to his turrets tanking
+ Great damage
+ Counters Bruisers in lategame with his tankiness and slowing turrets
+ Becomes Tanky with this build
+ Sexiest Champion in the game
+ Best dance and laugh in the game

Cons:
- Squishy without his items
- No jump or other escape mechanism other then slows and a possible stun
- Gets focused a lot because of your awesomeness
- Quite slow without items

I picked these runes because of some simple reasons:
You need armour in Jungle aswell as overall turretdiving and stuff.
You need magic resist for the lategame and such.
The Attackdamage is a huge boost for your damage during the whole game especially early on.

These masteries will boost your damage a lot and your overall tankiness in the jungle aswell as in fights.

Okay so I will try to give you as much explanation on this stuff as possible, I will pretty much give you my opinion why I think these items are good and what you could buy instead.

Berserkers Greaves: These boots are great for clearing your jungle and boosting your damage in fights and taking objects.

Blessing of the Elder Lizard: This item is great for jungling, you will get some additional damage on your auto attacks, this is TRUE damage, wich means that you will ignore armour with this damage, this damage applies on your turrets aswell, so you will get extremely good damage over time with turrets and this item. It boosts your damage, your sustain and is just extremely good in the jungle!

Blade of the ruined king: This item will allow you to deal damage based on the targets current health with the passive.
The item gives you attack damage, attack speed, lifesteal aswell as one of the best item-actives in the game, the active steal movementspeed and health from the target, this active is extremely good for chasing or getting away, and probably the best active when it comes to 1v1s.

Trinity Force: This items boosts your utility (with the slow and the additional movementspeed), your damage (with the attackspeed, crit and the Spellblade passive) and gives you mana and health, a great all around item wich fits most champions in some way.

Infinity Edge: Only one reason I pick this item and that is DAMAGE it gives you an insane damage boost wich will help you pick those APCs and ADCs off!

Frozenmallet: This item will give you a good amount of health and a little bit of AD, the slow is one of the main things about this item, you will slow each auto, this helps A LOT when you're heimerdinger, I get this item mainly because of the tankiness, this could be replaced by other survival items such as: Banshees Veil, Warmogs Armour, Guardian Angel, Randuins Omen, Sunfire cape and so on!

When using your E ability, try to use it where you think the enemy will be running to, it's a slow projectile and therefore can be hard to use

Use your turrets to tank buffs and objectives such as Dragon, Baron or a turret!

Your R will make it so that your Turrets slow their targets and so that your E will go faster when using, use your R when ganking, fighting or getting ganked!
