Basically this is the first guide that I've done and probably the only one I do depending on the feedback. I'm a gold league player, I play mostly Teemo so just giving some of my knowledge away. This guide may or may not work for you, personally I have a lot of success with it. You start of with your boots potions ward to be safe and not really worry about a gank before level 6. Once you go back and buy I suggest you go straight into a haunting guise for the ap magic pen and health. Teemo doesn't have a whole lot of health to begin with so it helps to build this item first so you can take a couple extra hits early. The Liandry's Torment should be your next item so that when you poke and harass with blinding dart your getting that extra tick damage in along with the extra dmg on your shrooms. After Liandry's it's really up to you how to build. You need to ask yourself a couple questions when you build your next item. A. Does the other team have a lot of AP champs? B. Am I just not doing enough damage? C. Are people getting away from me when I could be picking up kills with a slow or am I dying too fast? If you've asked yourself these questions then depending on which is the question that is write the following item should be what you build next. A. Abyssal Scepter, It's a great item if the other team is heavy into AP the amount of MR you get from it will keep you from doing to alot of 1 rotation champs like fizz. B. Deathcap, everyone that plays ap knows that if you're lacking on dmg you need to build a deathcap. C. Rylai's, The slow that you will get from your darts will allow you and others to catch up to champs much easier and the health from the item will make you much harder to kill. After you've decided which item is the next in your build you really just need build the rest of them items in whatever order you see fit.
