This is lux of the centuries build. This build is the one i use in blind pick with some other tones. Please dont follow this build completely. Work with it make it your own!

I have chosen these runes because with these runes you can rule the mid or bot lane easily with your early game ability output.

These runes were chosen for ruling mid or bot lane. The speed lux needs because lux needs to be swift. also because if lux didnt have that extra unc with the masteries she would never survive

These items were chosen for ability power and cool-downs. Al tho there is some flaws so don't copy this completely just make it your own get comfortable with them.

i start withbecuase it can be used really nice when running or just setting up a kill. is very useful for farming once u got ur first blasting wand itll be a breeze saves u from ignights and ganks it has saved me and my team mates alot.
is very useful when u need that clutch moment.

All in all this build has some flaws and also some good stuff use this build and you will be hitting it c: Have fun!
