Teemo Build Guide by Ferrovial

This is actually a pretty good guide, I did a few tweaks myself however to the items (like two things) but used your main ability sequence and your masteries and it worked really great. I found that instead of building a Frozen Mallet, building a Rylai's Crystal Scepter gives him the bit of AP bonus he needs to make his Mushrooms deadly and still gives him that nice bonus of health.

+1 :)

Wow, this build is really great. The only things that I would change is this: I would use Berserker's Greaves instead of the Dagger. But that's about the only thing I would change. The first game I played with this build I used these items: Doran's Blade - Berserker's Greaves - Malady - Wit's End - Frozen Mallet - Madred's Razors. My score for that game: 17-10-4. (And that is just because my team was absolutely dreadful.) +1

Great guide, definitely deserved the +1.

However, two things struck me while reading. The easy one first: I think the AP-Masteries in the offense tree are wasted. Your build does not rely on the AP-scaling and the only AP-item (malady) is used because it offers other awesome stats.
Of course you'll want to grab the 10% magic pen (and thus the CDR too), so I'd settle for something like →that.

Secondly, I'd like to clear up some calculation errors concerning attack speed. You wrote in the FAQ-section:

Even the stats-overview by mobafire at the beginning of guides is mixing up AS rates and item-percentages, so you're not alone. I'll open a ("suggestion")-thread about that in the forums soon.

Teemo has a base attack rate of 0.69, which is an important number for the whole topic. He additionally gains 3.38% of that rate on each level-up, so at level 18 he has 17×3.38%=57.46% in addition, which is 0.69×1.5746≈1.087. If you hover with your mouse over the AS in the lower left corner, you'll see that number at level 18 (there are two, this one is the first part).
The second value shown down there is the impact of items, runes and masteries. The sum of those two values can't be raised beyond 2.5, as correctly said in the guide. We already have 1.087, so 2.5-1.087=1.413 attack rate is left open.
The %-values of items, runes and masteries refer to the base attack rate, this is a common source for mistakes. So we have room for 1.413/0.69=2.0478... ≈ 205% attack speed stuff.
With Malady, Wit's End and Madred's Bloodrazor we've got 130%. Seals provide almost 7%, masteries another 6%. Summs up to 143%, or 183% with the passive.

So, we can conclude that if one wants to buy another AS item, maybe the black cleaver, not much AS will be wasted. We've got about 22% before the passive becomes partly useless and even 62% if one wants to max AS in general (which is probably stupid).

Cheers.
