Lux

Lux, The Lady of Luminosity

Lux is a long range caster with high Abilty Power ratios.  She is mostly used at mid, but can be a support champion as well.  

The best lux guide i ever read said something like "if you are close enough to ignite, you are playing Lux wrong."  Obviously there are times where this isn't true, but for the most part remember what her specialty is, long range nuking, and stick to it.  

Lux is a squishy champion and usually doesn't build much health because she is far from battle.  Gap-closer champions who deal high burst damage can beat her if she gets out of place, or lane bullys with a lot of sustain like a vlad.  Building MR is a must for late games against her.  If a team fight is about to start, try to bait her Q, Light Binding and E, Lucent Singularity combo and after she uses it, initiate so she fights while those are on cooldown.  

- Ability power scales well with Lux's skills.

- Max cooldown reduction brings her ultimate Final Spark to just a 24 second cooldown when lvl 16 or higher

- She can blow most champs up without even getting in range to be attacked. 

- Amazing Area of Effect spells for damage and control.

- Lux has a weak early game and is very item dependant.

- She is a thirsty champion and is next to useless when out of mana.

- Bursty or assassin style champions can neutralize Lux quickly because she is so squishy.

- She uses all skillshots, so if you can't land abilities, you're gonna have a bad time.
