I remember reading this guide 1 year ago. It really helped me a lot when learning Lux.

I am not a fan of lich bane since nerfs. It also is not that great in team fights as Lux should be played walking around the outside. I think sheen is a great item though, but I would not upgrade that. Perhaps late game it would be good.

I think Mejai's is a very op item on Lux if you have a big lead, it helps you finish the games.

In terms of runes, I used to agree with scaling AP runes. But at level 12, I do not see a big difference between flat AP runes and AP per level runes. I always use flat AP runes since the meta makes AP mids go aggressive early due to assassins. I saw GoldenGlue play Lux once, he went scaling AP, Hai noticed that. From that Hai did a level 2 all in and killed goldenglue because golden was defenseless. I think flat AP is essential for early harass because of that. The fact that Lux has an easy time getting kills at level 6 is true but I still think flat AP runes is needed for aggression early.

You can make the Lee Sin and Light Binding icons smaller by using so you get . This is better compared to just lee sin (and no size thing) which just gives .

Anyway you get my upvote because I love you for making this guide. You should make it longer :D

Just a quick note, you don't have to use remote resources to get champion icons and such. You might want to take a look at the BBCode guide.
