Teemo excels at harassing the opposing lane champion due to Toxic Shot and Blinding Dart.
You can use Noxious Trap as a way of scouting potential enemy ganks to protect you in lane.
You can use Blinding Dart to prevent your lane opponent from getting the last hit on important minions, like the Siege minion.
Your LoL Teemo build can focus on either attack speed boosting or on increasing your ability power (or a hybrid of the two). Usually it's a better idea to maximize your AP. Late game, single hits or traps will do insane damage and can poke very well.
LoL Teemo players may find him to be a confusing champion to build out properly. You'll find that his build varies when he is playing against either well-rounded or homogenous team compositions, meaning you shouldn't choose the same Teemo build every round of League of Legends
The best items to include in your champion's build are: Liandry's Anguish, Rabadon's Deathcap, and Horizon Focus. Those who included these pieces in their kits had a higher win rate than those who used other Teemo builds. Similarly, if you are facing a mixed enemy team composition, you should really consider grabbing him the Precision, and Resolve runes. In recent games, he won the greatest number of his rounds when built with these runes.
