Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
after much trial and alot of error, i've finally worked out a build that goes great for me.and hopefully you all too.
i'm not going to give you a whole pro/con, etc. there's a whole bunch you can read, i would recommend blue's teemo guide for strategy etc.blue's guide
i usually go first with, after that i go with, i then purchasefor some needed survibility, combined with your early AP and your, you should be last shotting with your team for much needed gold.
next purchase should be http://www.leagueoflegends.com/sites/default/files/game_data/220.127.116.11/content/item/3046.gif , you should be doing pretty good, mostly dependent on team collaboration and your mine fields, i would recommend mine spamming.
next item you should get, hopefully your going strong with the gold i would work for http://www.leagueoflegends.com/sites/default/files/game_data/18.104.22.168/content/item/3072.gif (x2) yes 2 of them as soon as possible, your fliping movement speed, attack speed and amazing damage should max out your double bloodthirsters, should be "GG" if not you probably have been dying alot and now need some "AnTi-KillaBle" item to make sure the enemy never wants to confront you 1v1.that would be, my last item is anotherfor that amazing crits and damage
Now alot of people are thinking " this is an expensive build","this probably sucks no armor pen" and more flaming
This build is expensive! and most definably does not suck! i've played alot of games with this build, i've played alot of games with many other builds, i've found this build to be a great early-mid-late game item set to get. even with the low ARP from your runes no one should be out damaging you with your trusty blind, poison and mines that you should be sitting by.( i almost always bait enemies to fight me on my turf! if not i fight with teamates. i'm a swifty assassin for a reason. i'm not gonna make dumb moves and i most certanly fight with an escape plan). plz comment if you have any commenting to do, "your dumb or stupid comments plz keep to yourself.
hope you try before you comment and make your own teemo build from what you've learned.
any questions to why i do what and why i picked what ask, and i shall try to fill you with my knowledge of why it works for me.
