Not Updated For Current Season
This is a build for teemo focused on a more defensive playstyle. Teemo is way to squishy to be in the front ranks trying to nuke.
With this build you will have slightly less than 100% (95% to be exact) magic penetration (the 15% penetration from masteries is not calculated in the total), meaning that the magic damage you do will almost not me mitigated at all by the enemyÃ�ï¿½Ã¯Â¿Â½Ã�Â¯Ã�Â¿Ã�Â½Ã�ï¿½Ã¯Â¿Â½Ã�ï¿½Ã�Â´s magic resistance. The shrooms will deal more than 1000 dmg, and the poison tick from your normal attacks for above 100dmg/sec. Blinding dart will hit for ~650. This translates to: 1 shroom followed by 1 dart and 1 regular shot will deal around 2200 damage total, and thats just the magical damage! Add to this the (low) physical damage and the damage from ignite and take that number up a even more.
Of course, not using any defensive items will make you die really fast if you are soloing and not placing shrooms for protection. So, with this build, shrooms and an escaperoute are crucial!
The shrooms will be your primary gankers, so place those in every bush and corner. Remember to use ignite aswell to add more damage to the DoT and further increase your ability power when ignite is on cooldown (due to masteries).
This build will harass and make the enemy run when they spot you, and the kills will start adding up really fast. Using this i got a triple kill from a shroom while i was waiting for respawn!
Best of luck to you all!
