[2.3] Pix on steroids - Lulu guide

Start with Boots of Speed - period. After the hard nerf to her skill range, poking with Lulu became extremely challenging. Having boots will allow you to get in and out of poke range easily. You will also be able to roam to river to help your jungler or go for a ward.

If your a player who likes to spam skills like I do, getting Sapphire Crystal and then Archangel's Staff is a wise decision.

Your core items should first be Ionian Boots of Lucidity paired with Redeeming Enchant for shorter CD and it will help you greatly on your first dragon. The second item that you should get is Ardent Censer . The bonus attack speed which will stack from both your Whimsy and the item effects are massive, and will help your adc more then anything. 

The next two items should be Harmonic Echo or Athene's Unholy Grail , and that depends on the situation: if your feeling safe and the enemy has little one-shot heroes, take Harmonic Echo . If the enemy Akali or Katarina are Licking their lips while waiting for you to overextend - Take Athene's Unholy Grail , since it gives MR.

Typically, you wouldn't get to a stage where you have more then 3 items, since you are playing support. But in case you do, I'd recommend Rabadon's Deathcap as your forth item, with either [Ludan's echo] or Morellonomicon as your last. Rabadon gives huge amounts of AP. Morello is good if the enemy has a lot of heal, and Ludan will also give you shorter cooldown, more ap and a nice addition to your glitter. 

DO NOT TAKE Liandry's Torment OR Infinity Orb ! a lot of people tend to think that the item effects will move on to whoever Pix is helping, but the truth is - she only applies the effects if she's attacking with Lulu . 

One last point, which should be understood when it comes to playing any mage supports - Avoid tank items. I understand that, especially with newer players, getting jumped on can be scary. But you also have to understand that buying tank items means less AP, which means your shields, heals and buffs also become weaker. The true potential to carry comes from understanding where to be, when to be. and once you master that, you'll find tank items irrelevant.

Also, Frontline is not your place anyway, which makes most of tank item effects quite useless.

P.S - Rod of Ages takes time to stack and has no supportive effects or cooldown reduction, so I would avoid that as well.
