Well, hello! This Teemo guide is my first guide and it's technically based off of Teemo: hybrid with an AP edge, but I believe I made a big enough change for my build to be in a new guide. I play pretty offensively and pretty much focus on getting the kill, as it's gonna reflect upon in this guide. Comparatively to jts2's, my build 1 lacks around 28 AP, but has 60 points more of AD. This gives a better overall damage output in team fights, since you're gonna be right-clicking a lot. I mean, yeah, with 28 less AP, sure, you're gonna deal a tiny bit less damage with your Q and your shrooms, but you hit a lot harder with your auto-attacks.

Pros

Easy to learn
Easy to killsteal
Really fast innate AS
Really fast movespeed
Nukey/burst
Blind stops auto-attacks
Hard to gank with shrooms as wards
Global taunt

Cons

Real squishy
Shrooms are easily detectable with consumables
Focused
Beaten by casters

See how there's two builds? Well, in this section, I'm telling you what the difference is.

Build 1
Don't be mistaken by its low attack speed percentage. 's on-hit effects does not factor in into the stats above, and nor does .
This is usually how I build my Teemo and is a newly developed between my friend and I. Build 1 melts people down, and it focuses on more DPS. It gives a nice mix of AS and AP, with a side of AD in early game. With Teemo's innately quick AS, coupled with build 1's burst damage, this will be a total kill-steal fest. Trust me, I'm an expert at it.

Build 2
I started out using Build 2, based off of jts2's build. This one, you don't really move as much, since you're just casting the **** outta your enemies. Build 2 is based more on casting Q and activating Lich Bane.

Always have your Blinding Dart first. Since this Teemo has a ****load of movespeed at level 1, you can rush the brushes, cloak, and dominate enemy AD carries. Blinding Dart disables their auto-attack, then follow up with Exhaust for some more damage reduction on them. More about Exhaust later on. Keep this skill on par with your passive poison E.

Ehh. Early game, not really as viable, since you shouldn't be needing to get in lane quicker or to gank. Damn useful for getting away of losing fights, sure, but earlier game should be more focused on poking, harassing, and farming. Get this a bit later.

This poison is real useful. It makes you hit quite a bit harder and it gives you damage over time. You can easily hurt and harass enemy champions with your Q first, follow up with an auto-attack, and falling back. Keep this skill on par with your AP blast Q.

dem shrooms. This is what makes Teemo such a ***** to fight against. It does a ***load of damage, slows, has vision, and shows you where enemies are. It's like a ward x100. Gotta remember to be shrooming it up at the Hotel Shroomifornia. Hit places to prevent ganks, escapes, and jungling. More on shrooming locations later.

To be completed later...

Core items

I really do think the Greaves are a better choice than Sorc's Shoes. You need the early attack speed, compared to MPen that you'll have later on. Plus, it balances better in the long run. You can't beat other champions when comparing damage output with AP in mid game, but you can shoot them a lot with your Greaves.

This is pretty much necessary. Without Rabadabadon's, your AP caster champ is way weak. As I stated previously, AS works out much better early game, since your poison actually can harass quite well in early laning.

During late game, with all your CDR in place already, your frenzic Q-spamming will activate Lich Bane an insane number of times during a team fight. This will give your Q more damage, and that your auto-attack will get boosted a lot, too.

Bang for buck, this thing is gives you the best value out of any item. It's so easy to get stacks with Teemo's auto-attack anyways, and on-hit with your poison is just great.

Viable items

During late game, to be honest, the MPen really means more than 20% attack speed.

I love this thing. Gives you some awesome CDR, lotsa attack speed, and much-needed mana regen. However, Guinsoo's gives you much more upon stacks and is much cheaper, too.

Wit's End is an interesting item. Sometimes, it's useful for the MR, but sometimes, you probably won't have much stacks on when they cast spells on you. Take caution when using it.

Necessity

Flash can and pretty much will save your *** on every champion you play. 'nuff said.

Top picks

As mentioned before, Exhaust gives you a double-AD-carry-screwer-upper by combining it with your Q. When you decide to focus an AD carry, hit them with a Q first, making them miss every shot. Keep auto-attacking. When they're out of their blind, hit them with Exhaust. They hit for less and move even less. While it's absolute perfect against AD carries, Exhaust also reduces ability damage on the enemy. Good stuff.

Just when that fink thinks he's gonna survive all your passive Toxic Shot poison and your magic shroom poison, you hit him with Ignite. Good for getting kills on stragglers, but not as versatile as Exhaust.

If you insist...

The reason why I don't suggest Ghost is because you already have your W. I mean, yeah, the more the better, but seeing how you won't be able to do as well in a fight really makes this a less-desirable option.

Red being DO IT OR ELSE TERRIBLE THINGS WILL HAPPEN
Blue being STILL DO IT, BECAUSE YOU CAN NEVER HAVE TOO MANY

Red is pretty urgent shroom locations. Dragon can provide a generous amount of gold, so use shrooms to ward it up. You can lead the Dragon into the shroom too. Baron, of course, at later game, since everybody would totally do Baron at level 6...

Be sensible; place these shrooms at escape routes, general wards, and traps. Having teammates to lure the enemies into shrooms is really beneficial.

These runes are pretty just generic AP champ runes. A good mix of everything you need. Some CDR, MPen, flat AP, and then some health for added good-luck.
Really, this part is up to you to go AP-based or DPS-based runes. I just play mostly AP, so this is what I had on hand.

Build 1
For build 1, the masteries are geared more towards the caster part of this champion. You'll have MPen and CDR and **** like that.

Build 2
In build 2, the masteries are focused more on the DPS part of this champion. You'll have more APen and AS and **** like that.

Welp, this is the end of my Teemo guide. I hope you'll use this build and try some of my tricks to help you to be a better Teemo player. Please, please, please give me suggestion and feedback to how to make this a better Teemo guide and make me a better player. If you're gonna downvote this to hell, please just say why so I can fix the problem and that way, we'll both be happy. Like other guiders? and tutors, send me back some scores if you've met this guide with success. I really doubt this would be really popular, though, but hey, at least I can say I tried.

If anyone would actually like to play with me, add me on...
