Teemo is one of the funnest champions to play in my opinion because he can blind, put out fast damage, and he has great map control. Not to mention he goes invisible ;)

Items

Strongly recommended

Runes

Teemo's runes can pretty much be any runes seeing as he's such a flexible hybrid champion however I like to use
3x

and 9x

I found that this rune set is the best (that I've tried) for teemo

Noxious Trap Locations

*Map Key*

Red Dots: place shrooms here first
Black Dots: ALWAYS have a shroom here after level 10
Purple Dots: "iffy" spots if you find people walk there alot
White Dots: Good spots to use your shrooms as a ward if you kill someone so you have time to run

How and when to use his skills

- Definitely an easy skill to use, your basic goal in team fights is to blind the dps/high ad opponents like xin zhao, trynd, master yi, etc if opponents have no ad's aim for tanks seeing as all tanks are melee with their attacks

- This skill is very fun to use (for me) just because you can get above 500 regular movement speed with it, basic times to use it are just when your running from ganks or your chasing someone

- Toxic shot is just a passive ability of teemo's this ability is really good because you can just attack opponents and if you get them to around 1 bar your poison will do the rest :).. nothing more to be said on this 1

- teemo's shrooms are a really good map control and or good for being able to kill those people that are jungling if you place them correctly, look above for more info on where to place shrooms :)

Will be updated soon
