now even more punishing AD
i had recent success and fun with the [new] item update. atma replaced with inf. edge, and bloodthirster sooner. you will like and agree. have fun peeps XD

It's almost like the new Teemo patch updates are made for this build - it's almost wrong how awesome and fun the AD stackage adds up ;D I'm having a blast!

Masteries updated: correction of error for Arcane Knowledge (boosting Magic Penetration 10% in Poisons), and I added Summoner's Wrath (since I encourage constant Ignites.)

Phantom Dancer just got moved forward, thus promoting survivability & devastation xD

The more I play this build, the more I love it. Once the items/weapons are half-built, the game changes - it's amazingly fun, so I hope it works as well for you as it does for me ;D

So...

HAVE YOU TRIED IT?

I want to know what you think :)
Feedback would be greatly appreciated. Thanks! xD

The guide's just been updated: replacing Mercury's Treads with Madred's Bloodrazor and adjusting the item build-order to compensate for movement-speed plus purchase-vs-damage efficiency.

~EN JOY`

I fixed a few errors in the Runes text. Hope everyone has fun with this build, as I have ;D

I concur Capt'n - I've found that works well too (also on my mind)
Hey, thanx again xD

In fact, you'll notice I really liked your idea [logical]
I tip my hat to you Good Capt'n ;)

I got the astronaut skin too; teemo with lazarz is too good. I generally run armor pen on him; even though he does a bunch of magic damage, anyone who attacks that quick really benefits from it.

Fulundry,
Thanks for your input - really excellent and I appreciate it ;)
I understand what you are saying about spell vamp. Interesting. Thank you for your thoughts! (Maybe I will swap those for damage quint's, not sure yet - need more $xp$ haha.)
Relatively speaking, as Teemo is quite targeted in general (and of course there are those team-up moments of d00m), I haven't really had too much of a problem health-wise, probably due to the armor runes and Quick Move, whereas if I do get Exhausted, I Blind to avoid immediate damage, flee with Quick Move and usually can escape (nobody's perfect haha.) It might be my play style, as I play safe as possible while feeding aggressively (something I picked up to survive and have a chance with the squishiest little furball.)
If you have the extra runes to try it out, let me know what you think.
The damage is pretty surprising and effective and it's nice because it builds quickly with a good interval for feeding / going back -ratio.
I dunno, I just try to have fun - I hope you smile at the AD melt-factor (like I said, part Items/etc., part classified YASA space-tech.)

btw: I will definitely try your guild when I get GP (which is on my list) Thanks for sharing :)

Few questions:

I don't think spell vamp on teemo is a good idea in general, and you're not building him AP. that means that you are going to heal 6% of 45 per hit, which is 2.7. Your shrooms are more of a map control device (again, especially with ad teemo), which means that you are gaining very little out of the spell vamp

Atma's with no health items? Teemo is one of the squisiest characters in the game; at least give him Frozen Mallet if you're gonna build that.

Finally, no health items/runes/masteris at all will not allow you to reach all that damage potential. If you get hit with one Exhaust you're probably screwed.

I like the damage, and your build does have your own flavor (which is nice) but the above seems like it could be improved.
