On my personal League Blog I made a strategical guide to Lux. However it's time my battle tactics get published on the forums. Lux is a champion that was once respected as being a powerful champion in the right hands. However as she grew old, new players tend to judge her based on her looks. Primarily playing her as a support because she has a shield and snare, and doesn't "look" powerful. I first became interested in Lux when I was playing against one. I too underestimated her because I've been told she's just a support. But boy did that girl roam, and by 15 minutes she got herself eight kills. Specializing in burst champions myself, I couldn't pass up this potential. For me she came naturally, so it was a perfect fit. In my guide I'm going to explain to you all of the powerful things about Lux I learned by accident.
Runes & Masteries
Marks: I chose regular magic penetration. This is for the early game ranged burst. Or, I would recommend scaling to be a late game powerhouse.
