Hello everyone!
This my very own guide for Lux! :D
I've used this build for such a long time, and it never let me down.

The reason why you rush sheen early, is for the extra mana and AP also the delicious passive of sheen scales with passive, which means extra extra damage from your passive GG!
Of all the Lux-players I've seen, I'm the only one who rushes Sheen. Also I've never lost vs another Lux. Bad or Good.

You need alot of CDR(Cooldown reduction) on Lux. That's why you have the Morello's evil tome.

There's 1 exception in this build. If your jungler doesnt give you blues, you should go Chalice > Athene's unholy Grail for the mana regen. But if you're premade with your jungler or if you know he will give you blues, dont mind going Chalice.
Well.. that's all! Have fun summoners ;)

Also, the armor seals counters when you're being ganked. I've experienced 100 of times where I've been ganked, even though Lux is very strong at escaping, so remember that!
The feeling of being abit safer if you're getting ganked is always good.

Early game you should save mana for combos when your enemy makes a mistake. You can of course use your E to hurt the minions for a easier lasthit. - Thats what I do atleast ;)
