Not Updated For Current Season
Ok, so I don't really know who read this **** since you just need to look at the items, runes, masteries and the skill sequence to have a fairly sweet Teemo / LeBlanc / Dr.Mundo, but I have to write a 300 character build description to get a ''complete'' build.
Ofc. this is just my opinion of how the builds should look like. So you can ofc. think a little bit outside the box if you want to.
Teemo: So for Teemo I'm starting with Blinding Dart for harrasing, that's also why I choose to buy boots from start (you also get money over to buy 3 health pots). Then I buy Meki Pendant (mana reg.) since your mana disappears kind of fast when you are harrasing. Late game I just keep buying attack speed...
LeBlanc: I'm starting with Distortion, i'ts good for harrasing and escaping. Save it untill you're lvl 2 and hav Sigil of silence. Then you can attack with Sigil of silence first and then attack with Distortion and then jump back without being attacked. Mana is not a big problem for LeBlanc late game if you play as I do, but it's a problem early game that's why I choose to have 2 Greater Quintessence of Replenishment. Items is focused on Mana reg. early game and Ability power late game.
Dr.Mundo: Mundo is both a great tank and a great damage-champ. One thing you have to think of is that early game Mundo is NOT invincible, HE CAN DIE!! So wait until lvl 6 (at least) to tank. Early game it's good to have boots of swiftness since you can run back and forth, from side to side and throw your cleaver at your opponents.
