Welcome to SHACO AP guide.For start , let's talk about Shaco.
Shaco it's one of the most FUN champion to play,very hard to catch,boxes,shivs and yea..got the worm dance! *dance*
K so let's begin..

For runes i take a standard mage runes like Magic Penetration x9 for marks , Mana Regen per lvl x9 seals , Ability Power x9 glyphs and Ability Power x9 quintessence

We start with Doran's Ring..why? because give health , mana regen and ap..we need them all..and the hp bonus its pretty good to dont die..maybe..
We continue build Boots of Speed continued by Fiendish Codex.. MANA REGEN AND AP , YEA!
After we done Boots of Mobility we go for Morello's Evil Tome..more mana regen and ap , double yea!
And we finish with Rabadon's Deathcap and Rylai's Crystal Scepter.
The last 2 items depends on how you play or which you are vs.

Deceive

- can be used to escape , gank , or just pass by to not be seen

Jack in the Box

- that's why all don't come in bushes when are vs shaco..just be sure you are planting them in your escape way or kill way

Two-Shiv Poison

- just an ability that do dmg..and when i say dmg i mean A LOT OF DMG + slow , at high lvl they gonna hate with

Hallucinate

- one of the most awesome skill..you can do everywith you with clone like escape (hallucinate -> deceive) , send him around to kite or to see in bushes (controlate by ALT , keep press ALT and use mouse) or one of my favourite to kill!..they are low hp at turret? no problem , hide somewhere , press R and send the clone at him..and boom DEAD! ..not always..

For summoner spells i take flash and ignite.

Flash - to escape seriuos ganks or if Deceive its on cd
Ignite - we always get mad if the escape with 10 hp right? -.-'

I just started it , still updating when i got time..
