Hello and welcome to my awesome guide to own with teemo.
Following this guide might not win you the game but it sure will make playing teemo much more enjoyable. lol? idk

The reasons for the runes I use is because it adds quite a lot of AP in the beginning of the game and some defense since your squishy and targered a lot. Also, having that amount,whatever is shown at the top, will help you own and get kills in the start with the poison damage which is not cared by many poeple. I got lots of kills with the passive on my E and it also saved me by making the nemy scared of me C:

The masteries are pretty much straight forward. I went with the classic AP materies due to how much extra AP you get in the beginning/mid/late games so not much to say here.

The reason for the weird build of AP and attack speed is because it is awesome. I love going AP with teemo due to his Q/E/R. His Q does a lot of damage when you increase your AP and your E is just beautiful watching the enemy melt after getting hit just once by your melee. Your R is one of the main reasons why AP is so important for teemo. I believe that teemo's job is to shroom(aka plant R)whenever and where ever possible. Teemo's R + high AP = super strong slowing mines that last 10mins after planting. That is just awesome. The reason for the attack speed is because it makes you stronger when actually fighting people and not just shrooming. A lot of peopel underestimate teemo when fighting 1v1 or 2v1 when teemo is alone. After you complete the build, which might take a while, it is worth it every gold. You can own anyone from AP to AD to Tanks who think your too weak to damage them. These are the ultimate items that make teemo the Teemonator.

I really don't get why people need help with this part because this is just nonessential.....atleast for me I dont find it that important. The skill sequences all depend on the situation and on the way the person plays and it is their choice to make.

Flash is everyone's bff. It saves more lives than anyother skills would. I use to just ghost all the time because I would be fast for a long time but hey guess what, if the enemy stuns you or drags you back what happen? RIP
Always take flash and remember to flash through walls.
I take ignite for early kills and to help with 1v1 and finishing kills that just need that little more damage. So remember take these two.

In conclusion thanks for reading this awesome teemonator guide that I made and btw this is my first build so understand if it isn't as cool as the other ones where there are pictures or videos of skills or items where you can move your mouse over to see the stats and what not. This build should be used often as I have owned with it and it makes you feel strong. Just try it and please leave comments and votes and tell your friends about it even if it sucks or rocks. Thank you again and hope you enjoy your next game with the teemonator lol.
