Hello This Is my first build which I want to give out to all the shacos out there. I am pretty new to MOBAFire so dont expect much a fancyness
I've come to the point where I want to share my epic ownage with Shaco.
I've had more than 300 games with Shaco so far and got influences from HC Patonki. Before you even ask, Yes I have tried Jungle Shaco, AD Shaco and The +80% AP Shaco build. This being said, I want to share my opinion about these three fellows. Jungle Shaco, I Find him very viable and great jungler/ganker. He packs nice stress to the enemy team but ends up getting killed and gets disabled by Oracles. AD Shaco is plain useless and doesnt need that much of introduction.
The AP Shaco which has +80% In MOBAFire is also nice, but it just misses the 'Magical touch'
Now we get to my build. Just follow along and please feel free to try the build before voting.
KThnxBai ~ Sincerely, Mirguloz

PROS
-Great Damage
-Serves more help to your team
-Makes people angry.
-Huge fear with damage.
-Great ganker

CONS
-Gets you easily killed if not used properly
-New Players use to forget the Active on DFG
-Only one AOE ability
-Gives you nightmares

So The Runes gives you great advantage in every situation.

-Magic Penetration Marks, Simple reason. MOAR DAMAGE !!!

-Mana Regen Seals, Another simple reason. You will run out of mana too easily in early game.

-CDR Glyphs, Not so simple reason. These can be replaced with flat AP glyphs, but this means you need to buy CDR Boots instead of MRP. These also give nicely lower CDR to JiTB :)

-Quintessences, Theres 3 kind of quints to use. I personally love the flat AP Ones, but also Movement speed and HP are viable to cover up the missing speed or the early HP :)

My masteries are again just my choice, and i use these, because the UTILITY tree mixed with a little bit OFFENCE, just does this build even more insane. You will never run low on mana, and if you think you still does, then just take the Bluebuff. It shouldn't be a problem, when you Spam those JiTB in the beginning and use the following masteries/runes.

I shall just simplify that with these items, I Guarantee that you will rip new ********s to the enemies. I'll explain the items easily and short why these ?

-Doran ring, Gives you everything you can ask for early game. It grants you AP,HP,and Mana regen. These three things are the 'key' to pure ownage.

-DFG (Deathfire grasp), This Items active and Two-shiv poison deals the most annoying damage that you ever imagine. Lets say you have Veigar just farming like a ******** in the mid lane. You pop your ghost, then Deceive, get to the range and throw DFG + Shiv. That almost packs up the kill, If not, Just poke the ****er with ignite and that should finish it.

-Boots, This is the item with two choice. If you decide to take the Flat AP Glyphs, You will buy CDR boots for JiTB and Shiv. If you decide to take CDR Glyphs, Then I highly recommend you to take the Magic Penetration boots for MOAR CARNAGE !!!

-Rabandons deathcap, Why would you even question this ? OFC YOU BUY A EFFIN' OP CAP !!!

-Lich Bane, After purchasing this item, Only GOD can stop you. With DFG + Shiv combo, Boxes, Deceive and this items proc between every makes everyone lose their butt virginity in a sec or two.

-Rylais Scepter, One more item which gives you all you need HP And AP. This is extremely dangerous combination when it comes to JiTB's and Rylai's realationship. These two makes baby jesus cry.

-Void Staff [Sell D.Ring and cover with this], Oh dear Why ? Because we demand more PENETRATION TO THIS FIELD OF JUSTICE !
