First of all, I hate writing in English.
Maybe it's because I write badly. So sorry for any possible error. =D

This guide has as base my tactics of the game with AP champions.
These are champions that I play but i belive that can be utilized for others.

Let´s go...

How can be observed, are utilized the same for all champs.
I like them because magic penetration is so good in early game and ability power in lvl 18 is ecenssial.
But nothing prevents other configurations ;D

As Runes the Masteries are the same for all champs.
The tactic is distribute the points in mana, mana regen, ability power and magic penetration.

One the best way to ensure the growth of champ and of the team is remain the longest time in lane. For this it is necessary have health regen and mana regen.
For these reason all my champs begin with Philosopher´s Stone, so that also give money.

Ahri
She consume too many mana. After philosopher´s and boots i recomend buy more mana (catalyst the protector).
Your skills not produce high damage. Then buy itens with cooldown reduction and magic penetration for the skill spamming.
Will of the Ancients it is good for complete your passive.

Fizz
This champ is too over power.
He is a melee and ablility power atack. So Sheen is essencial in begin and late game will transformed in Lich Bane.
Because he is melee, he need life. For this Giant´s Belt is so good and in late game will transformed in Rylai´s Crystal Scepter that of more ability power and slow.
Magic penetration (Void Staff) also is good.

Lux
She is a KS Queen. :D
Very attention for play with Lux. You can´t die. NEVER.
I´m joking :P But avoid die because your secret is Mejai´s Soulstealer. Before ending the boots buy it. Your cooldown reduction it is a very important.
Lich Bane is very important too, but in late game is so better.
As well as Ahri, Lux consumes much mana. Buy Catalyst the Protector.
The Void Staff is important in early game.
Never forget to buy Wards.
No one escape the Lux.

LeBlanc
She is a full magic penetration.
Void Staff and Haunting Guise are very important. But life also is necessary therefore buy Giant´s Belt and transform in Rylai´s Crystal Scepter in late game.
Will of the Ancients save his life.


I have not mentioned but Rabadon´s Deathcape is extremely important for all champs!

Before anything...
Ever improve your ultimate!!!

Ahri
For she it is necessary all skills in lvl 3. But after improve only Skill "Q" beacuse you need early one great skill. Then improve all "W" because "E" not will make a diference.

Fizz
For he get first "Q" skill. Nice for a first blood.
After that, get "E" to escape from enemies :D
Then improve only "W". This skill will take more damage.
Thereafter, i like to improve only "W" skill. It is not damage in area.
Finish taking "E" skill.

Lux
Ignore "W" skill. This will not make a diference in early.
Start taking the "E" skill. After take "Q" skill. Merge this skills.
Only late game, get "W".
The "E" skill is nice because take a good damage.

LeBlanc
First pick "E" skill. This good for pick up your enemy and take a first blood. But then no improve this skill.
Take "Q" and after "W" (you can escape now :P).
Then only improve "Q". This skill is important for the ultimate.

Lux - Mejai´s Soulstealer:
If you are very concerned, and die a lot, can not join the stacks and the items will become useless.
However, if you can keep 20 stacks, will have enough Ability Power and big Cooldown Reduction.

Fizz and LeBlanc:
It is an expensive build. If you can not make money, will be left behind.

Ahri
Nice for save their allies utilizing your taunt (Skill "E").

Fizz
Your ultimate of a large damage in the area and slowing the enemies.
Your Dash (skill "Q") can save your allies killing enemies

Lux
Ok, your ultimate is a great KS. :P
But it also save your allies.
Skill "Q" hold the enemies and "E" slow they.
Furthermore, Skill "W" give a one shield for your allies.
Nice champ for Team Work

LeBlanc
"E" skill hold the enemies allowing that allies escape or kill they.
In combination "Q" and other skill, the enemy is silenced.
