Not Updated For Current Season
Normally you would say; "Why don't you get lifesteal first!" or "Critical is for Noobs!" or even "Attack Speed is the Best!".
Well this is a mix of Damage and Critical.
(Note; I'll continue to update now and than.)
I start off with a Brawler's Gloves for the 10% Critical Chance since it really does deal a lot of damage, I also get 2 Health Potions because I find lifesteal very useless with Teemo since you don't go dps till the end.
I than temperately get a Berserker's Greave for the Attack Speed and Movement and if you have enough quickly get the Zeal for the Critical Chance and Attack Speed.
I than go for the Damage and work on the Infinity Edge, depending on your money, if you have 1,850 than get a BF. Sword. But if you have 975 Gold get the Pickaxe even though some of you might want to save for the BF. Sword.
