Hello. My guide centers toward Ability Power Lulu, focusing on her build and skills. Lulu, The Fae Sorceress: Ability Power is my first guide. There will probably be a couple issues on the coding, formats, and my runes/builds/masteries but I'll try to fix or improve it as soon as possible. Also, please try it before commenting.

You're welcome to leave feedback or advice. :)

Pros

-Ranged Champion
-Easy Poke/Harass
-Escaping is Child's Play
-Polymorphs Enemies into Squirrels

Cons

-Usually Focused
-Mana Consumed Quickly
-Squishy Early Game
-Will Probably Take Over The World With Squirrels

The Offense Tree

Greater Glyph of Scaling Mana Regeneration: More mana regeneration!
Greater Seal of Scaling Mana Regeneration: Even more mana regeneration!
greater quintessence potency: More ability power!
Greater Mark of Ability Power: Even more ability power!

Great Summoner Spells


Flash: Flash allows you a quick, fast, escape out of ganks.


Ignite: Ignite can finish off the enemy champion, or cast this on him when you both are at low Health to ensure you get the kill.


Heal: When in team fights, use Heal to restore some health and get your allies back to their feet.


Decent Summoner Spells


Ghost: Using Ghost will let you either run away, or chase from/an enemy.


Exhaust: Like Ghost, you can either give chase by slowing them down, or escape faster than your chaser.


Teleport: Using teleport can get you to anywhere quickly, but it's not useful when in fights/chasing/running away.


Clarity: I can't decide whether to include this or not, but I will anyway. Using clarity will give you mana, but using it means you're just spamming attacks and consuming mana too quickly. But then again, it gives you mana. :D


Other spells, like surge, smite, promote, or revive aren't that useful. You can consider Cleanse, but I don't use it a lot.

I max out Help, Pix!, Whimsy, and lastly, Glitterlance. Level up Wild Growth whenever it's possible.

Glitterlance: You and Pix shoot you a bolt that slows enemies by %80 for 2 seconds. One bolt can only hit one enemy. Use Help, Pix! on an enemy, allied or enemy minions or champions to get a easy shot.

Whimsy: You can cast this to give you ability power and movement speed for a short period. Or it can turn someone into a squirrel. I prefer the latter.

Help, Pix!: Attach Pix to an ally as a shield and helper, or to an enemy champion for damage, easy shot with Glitterlance, and vision of them.

Wild Growth: Lulu's ult. She heals an ally, and makes them twice their size. Use it on the major damage dealer when in team fights, or on someone who has very low health.

I get Faerie Charm in the beginning for mana regeneration, leading to philosopher's stone. I also got Ionian Boots of Lucidity. Then Rabadon's Deathcap, Morello's Evil Tome, & Deathfire Grasp for tons of Ability Power. The last slot should be for something like magic resist, armor, or mana.

This is my hopefully short, simple, and effective guide to Lulu. It's not that great, but please let me have some good feedback? :D I know it's not the perfect Lulu guide, but you'll be able to play her and make at least some people rage at you. :)

Good luck, and have fun playing Lulu!
