Lux Build Guide by NegIected
Not Updated For Current Season
For runes i chose AP runes because you would want the huge burst at the beginning so it would be easier to kill and get fed.
I chose Cool Down Masteries so all your ultimate can have a lower cool down. At level 16 if you get the items then you will have 24 second cool down on your ultimate.
For your summoner skills i reccomend Flash ignite because your jungler will give you blue so its useless for Clarity.
