Hi, I'm iDemiZe and this is my first build. Teemo is one of my favorite champions of all time, his poison is incredible, he gets all the kills, and a Multikill is easy for him. I just want to show you my Mid strategy for him/her (does anyone know yet?) Hope it helps!

Now for Teemo I would go for x9 of Greater Mark of Desolation, because I feel he isn't strong enough beginning game to hold himself up without a little extra pack to his punch. For my Seals I recommend x9 Greater Seal of Alacrity, because Teemo's poison impact damage for Toxic Shot is a wonderful HP dropper in my opinion, and the faster you attack, the faster they die. For my Glyphs, use x9 Greater Glyph of Malice, now you could switch the Seal and Glyph around whenever you want, because the AS loss on your Glyph isn't that bad, but the Crit Chance difference between the two is bigger, it all depends on if you want to focus your AS or Cc. The Crit chance rune on Teemo i recommend because if you can land some crits on your lane enemy it provides much more efficient dmg. output, which is never unhelpful. Last but not least are the Quintessences. These 3 are optional but i absolutely think they are the most effective Quints. They are: Greater Quintessence of Desolation, again because the ArmP helps, Greater Quintessence of Malice, and Greater Quintessence of Fortitude, b/c Teemo is a low base HP char. and the more hp the better.


Greater Mark of Desolation Greater Quintessence of Desolation

In Offense-
3/3 Deadliness (If your crit runes aren't sufficient this is helpful)
1/1 Cripple (Exhaust is one of my main summoner spells and you do more damage to the enemy while it is active)
1/4 Archaic Knowldge (So you can get Havoc)
4/4 Alacrity (Again with the runes)
3/3 Sunder (Must I say it again?)
2/2 Offensive Mastery (Easier Farming = Faster GP)
3/3 Brute Force
3/3 Lethality (More dmg. to your crits which are more likely to happen ^-^)
1/1 Havoc

NONE for Defense


In Utility-
3/3 Good Hands (You're mid, less time Dead is good in its own way but its also helpful because while your dead, early game mid can level up 2 or more than you are currently, which makes you alot more vulnerable.)
1/3 Preserverance (Switch GH and P up if you want it's not my choice)
4/4Awarness (Gotta love leveling faster)
1/1 Greed ($$$)
