Pros:
*Tons of health, 4.5k with the full build
*Decent early game damage for early kills
*CDR really speeds up team fights and farming
*Enemies will eventually come to realize you are not an easy target, letting you support your team with little interference

Cons:
*Not as much damage as some more AP centric support builds
*Semi expensive build that will require you to do some extra mid-game farming

This build is for support Lulu, and when finished, you will wind up with 4.5k HP, and some decent damage output with some handy CDR to boot. I usually wind up with at least 25-30 assists and after much fussing around with Lulu, have found this to be the best build for my play style. You will be able to survive almost anything heavy damage dealing champs throw at you late game and the extra CDR will let you fully utilize Lulu's skill kit to give your team a winning edge during fights.

I wanted to state that I usually grab one Greater Quint of Insight to put my MP at an even 10, but for some odd reason they are not showing up in the rune builder. So it's 2 Potency Quints and 1 Insight.

I go with a 0/21/9 mastery page to give Lulu early protection, as it deceives people into thinking she will be an easy target or gank. The health is essential to the build, and the CDR helps and pairs nicely with the boots of Lucidity and Frozen Heart.

I pretty much stick to this build, but will sometimes use Merc Treads if the enemy is AP heavy, or Sorc Shoes if more damage is required. Also, building Deathcap before Rylai's has worked out fine, but I find the extra little bit of CC and health is nice to have earlier, allowing you to last longer and it compliments Lulu's kit nicely. I never had mana issues with Lulu, but Morello's Evil Tome could potentially be used instead of Rylai's if you feel like Reverie isn't giving you enough of what you need.

I like to max out Glitterlance first as it has a low CD and will be your main source for getting needed farm, as well as allowing for the maximum slow to let your teammates finish off any enemies that try to run.

I like to go with flash and teleport. Teleport specifically for being able to recall and return to lane quickly early on, and to be at team fights later if you happen to be off farming somewhere.

This is the first submission I've made to Mobafire and has served me well, hope you enjoy it. If you have any suggestions or improvements please don't hesitate to leave a comment
