Please don't spam comments, if you didn't like my guide and want to downvote, comment and explain why. And for you that want to upvote, THANK YOU and I hope I could help you improve your comprehending on this fascinating game that is League of Legends!!!

I suppose you might be asking yourself who am I and why the hell I think I can write a guide?!! Well, first of all I wrote this guide for my own growing and OF COURSE BECAUSE OF YOU!
I play Lol since Season 2 and my current division/tier(Elo) is Diamond V. I play in the brazilian server and my nickname is Gikuza.

For masteries I strongly recomend the 9-21-0, but if you are willing to make more damage you can try 21-9-0. If you are on the Bronze,Silver or Gold I would recommend 9-21-0.

The Elise AP > TANK , as I said on the beginning, is my most common build ( I use it 90% of the games) and also made up for when you get an early advantage with gankings or kills.

Spirit of the Ancient Golem must be built every single game, unless your team is wayyyyyyyy ahead in gold. Then you can try Spirit of the Spectral Wraith

It's very important for this more AP elise that you get the magic penetration needed with the Haunting Guise and the Sorcerer's Shoes so that you will start hurting a LOT <3

Liandry's Torment and Rylai's Crystal Scepter will give you the damage you need to burst a squishy enemy such as the ADC or APC.

After finishing Spirit of the Ancient Golem, Haunting Guise and Sorcerer's Shoes you can choose between Rylai's Crystal Scepter(if your team is ahead in gold), Spirit Visage(for sustain and if the enemy's APC is fed) and Locket of the Iron Solari(for team fights)

We're almost there!!! A phew more tips and you will be ready to become a pro with elise!!!
The skill sequence is very important to explore all the damage she can cause.
For Ganks(after level 3) you start in the human form so that you can hit the stun. After the stun you use your "W" and "Q", then change to spider form to finish the combo using "Q" and "W" again.
You might aslo use the "E" after to kill the enemy champion. In other words: Cocoon--> Volatile Spiderling--> Neurotoxin--> Spider Form--> Skittering Frenzy--> Venomous Bite and sometimes, after using the combo, you might need to Rappel--> Neurotoxin or Venomous Bite

Pros:
-Strong gank early game
-Hard to be countered
-One of the fastest champions at making the jungle
-Can easily solo the dragon in the early game
-Great sustain while in spider form
Cons:
-Does no damage if you doesn't hit the combo
-Once it's behind in gold becomes squishy
-Vulnerable when abilities are on cooldown
-It's late game usefulness depends on early ganks(kill/assists)

To become a good jungler you gotta know how to make the jungle, thereby here am I to help you <3. So, for this pre-season and season 4 you should start your jungle always on the bot lane side. If you are on the purple side you start at Blue, if you are on the blue side you start at red. With the pre-season changes now you can smite the blue or red(depending on wich side you are) and you have time to smite again when you go to the other side of the jungle.Once the Blue/Red has spawned at 1:55 you gotta smite it right away. After you have got the double buffs you do either wraiths or wolves to get level 3. Once you are level 3, feel free to gank or continue doing the jungle. It will depend if you can get kill/assists ganking or if the lanes are too advanced.

Here I will show some match-ups against others junglers.

- hard - you can't counter junge him unless you get an early kill over him

- easy - you have more potential damage, thereby you can counter him.

- medium - he has as much damage as you early game, so will only depend of your individual skills to counter him.

- hard - same thing that lee sin.

- medium - He is quite tanky, dont try counter-jungling him, but for sure you can counter-gank him

- medium - He get low most of times on early jungle, if you can caught him low, doing jungle it's a SCORE <3

- easy - In 1v1 you can easily win the trade

- hard - don't try 1v1 him cause you'll die :(

- hard - he can trade pretty well because of the sustain

- easy - Easy to counter jungle once he is pretty weak until level 6

- easy - If you hit the combo, congrats! You've just killed him <3

- hard - You can counter jungle/gank the same way he can

Elise is a very OP champ, but you need to get used with her first(I'd say 20 games or less). Before choosing her, make sure your team has a INITIATOR, because she isn't.If your team doesn't have a initiator and you gotta initiate the TF's make sure you're tanky enough. I know you'll enjoy playing Elise because she can make very funny plays such as epic chases, early kills and escapes <3
