Hi summoners, I'm Light no Ning, first of all, sorry for my english, I'm spanish. This is my first guide that I write on mobafire, so I hope you enjoy it.
I actually play at EU server, add me if you want so we play together :) .
Since I started LoL (long time ago, june 2010), I saw that the characters I played the best were the AP. I loved mid lane, and I improved my skills more and more. This guide is for Gragas, but I will probably make also guides for Swain and Lux.

PROs

-Extremly nice farmer
-Nice Ap ratios
-3 AoE skills
-Nice durability thanks to W and passive
-Combo will deal lots of damage

CONs

-3 skillshots, needs skill to master
-You can save your enemies with a bad throw of [EXPLOSIVE CASK]
-I dont know more... do you?

I take Greater Mark of Magic Penetration for the extra mag. penetretion. Combined with the Sorcerer Boots, you will break most of the Basic magic resis, which is 30.
Usually, I choose Greater Seal of Scaling Ability Power because it gives really nice ability power at the end of the game, but i also recommend Greater Seal of Scaling Mana Regeneration for the mana reg.
For glyphs, I take Greater Glyph of Ability Power, for the extra ap. I take Greater Quintessence of Ability Power for the same reason.

For masteries, I go with the basic 9/0/21, placing the point at the flash mastery.

I start with the Doran's Ring and go to mid lane. Doran's ring is a really good item and really cheap, which will help you a lot in the lane. That 100hp, 15 ap and 4 mana/5secs are just fantastic. When I get the neccessary gold, I go b and buy the [Boots of Speed] and, if I can, another Doran's Ring. Also, I take 1 or 2 red potions. With this, you will be really powerful at lane.
I upgrade the Boots to Sorcerer's Shoes as soon as possible. If you are getting CC'd a lot, then Mercury's Treads are also a really nice item.
I start building the Rod of Ages by the catalyst the protector. Extra HP and mana, and also the regeneration when lvl up. This item increases a lot your durability at lane. I finish the Rod of Ages, then go to Rabadon's Deathcap, then Rylai's Crystal Scepter, Banshee's Veil and finally, I usually take a Guardian Angel, but a Abyssal Mask is also a really nice item.

Gragas is a character with 3 skill shots (as lux, well, counting the shield, she has 4 skillshots), but they are easy to use (they are fast, compared to other skillshots)

The skill sequence is really easy to follow, Explosive Cask> Barrel Roll> Body Slam> Drunken Rage. Be sure of using Drunken Rage whenever possible for the extra AD for lasthitting and restoring your mana in lane. It is also good for getting down towers. The combo of Explosive Cask-> Ignite-> Barrel Roll-> Body Slam is really powerful, and your opponents life will get down in just a moment, if not died. Also, try to use Drunken Rage before using Body Slam for the extra damage, Body Slam scales with AP and also with ->AD<-.

I choose Flash and Ignite.

Flash is a relly good spell (if not the best of the game) for every character. Gragas also has Body Slam, so whit Flash and Body Slam you have a nice escape and chasing method. You can pass over two walls at the same time, you can tower dive easily, put out of range of tower, etc.

Ignite is a really nice extra dmg. Added to your combo, it will be devastating. It is also really good for champs who heal a lot such as Vladimir, Dr. Mundo and Swain.

Alternative summoner spells:

Ghost : The alternative to Flash, I use it with Lux, and it works also well with Gragas. If you chose this spell, remember to change the mastery tree at the utility part.

Teleport : It's ok, as you go to mid lane. But I prefer Ghost or Flash over Teleport.

Not to choose:

Clarity: Gragas is mana hungry, yes, but you have your Drunken Rage and a lot of mana reg, so why do you want clarity? You don't need it.
Fortify: I've seen lots of Gragas with this spell. I don't recommend it, if someone is taking it, you must not be that one. Let it to the tank, you are the AP carry.

Well, my guide is finished. I know it's not the best guide ever, but if you comment and vote it, you will make me proud of it, even if the commentaries are bad. Thanks for reading my guide, and see you in the game!
