Thanks for looking at this guide, I will try to go into detail about the items, runes, and masteries that I have chosen but please, before rating or saying the build sucks... Try it out for yourself, see what you think.

I think the runes are rather self explanatory and I'm not really sure what to say about them. extra attack speed, some defense, and an exp boost for when you are soloing. (Which you should be doing a lot of...

Lots of damage and AP. The spellsword is a MUST on teemo, and of course attack speed... I put 3 into utility for mid/late game roaming and mushroom placement. Of course this reflects playstyle and should not be followed to the dot.

Alright so this is probably the most important section because this is what the guide is all about... Alright let's go through each item one by one.

1) Doran's Blade:
This item is a rather simple choice. Of course, you can decide to go boots 3 pots, but I prefer to get an advantage of damage and health over other player right from the start. This will be explained more later.

2) Beserker's Grieves:
I get beserker's grieves next, attack speed is the essence of on-hit teemo and the movement speed advantage is a must.

3) Malady:
In my opinion, this has always been a MUST HAVE on teemo, the attack speed... the extra damage on hit.... decrease enemy defenses... yeah... Oh and a bonus of AP too...

4) Wit's End:
Wit's End is exactly the same as malady except it increases your MR instead of decreasing your opponent's.

5) Blade of the Ruined King:
Ah yes, This used to be Madred's Bloodrazor but it has recently been replaced by this... A buffed version :) This awesome toy makes you the on-hit ninja of doom that you are, It defines your essence... Just get it......

6) Liandry's Torment OR Runaan's Hurricane (recomended):
:) Two of my new favorite items. these do so much damage it's not even funny... But then again it really is. These items will make your opponents cry...

7) Frozen Mallet:
Last but not least, Frozen Mallet. This thing is great. It slows everyone on-hit. You might be seeing where this is going, THIS THING GOES AMAZING WITH LIANDRY'S TORMENT!!!! Slow em and then use a ability like blinding dart and BAM 10% off their health.

BOOTS:
You can upgrade your boots to whatever you want. I usually just get the speed increase but it's your choice...

FARMING IS A MUST. You have to farm a lot and get fed early game. That's why I suggest middle but you can manage bottom and top too. If you don't farm, your screwed. SO FARM! Last hit... Don't just auto-attack....

Early Game:
Farm, farm, harass, farm, kill, farm.... you get the idea, Play aggressive.

Mid Game:
Stay in lane for most of mid game. Be more aggressive and kill the enemy laners. Get Fed.

Late Game:
As long as you are as fed as you should be just go out and pwn some faces. If you are not as fed as you should be then be cautious, stay by your team and get gold and exp to keep up with the opponents. Good Luck :)

Farm, play aggressive, and you will become a nightmare to your opponents. Thanks for reading, post any suggestions you have in the comments.... Don't complain too much about my runes, masteries, or skill order. That's not what this guide is about....

Good Luck :)
