Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This Lux build was my real first attempt at not only tinkering at existing builds, but crafting my own.
Lux is really squishy and you have to keep that in mind. Her greatest weakness is basically that she gets free damage after every spell when auto-attacking via Ilumination, however that will put her in harm's way, as she should ALWAYS dance in the back. While you really need the extra damage output of Deathfire, which has saved my live and many 1v1 fights countless times so far (okay 6) there is a differing build if you rock, which you will-
If yuo feel yourself dying once too often, stay with Deathfire and Rylai, if you get insane, switch them out for NASHOR'S TOOTH then LICH BANE, to really dish out some damage after your already brutal spells.
Concerning her spells:
I always try to lead them in with my sphere, the slow is good and allows you to hit your bind. In a teamfight, the sphere also adds some nice protection with its slow. Hit it where the fighting is, DETONATE, and then auto-attack once or twice. They should be dead. If not bind, attack, and see them fall.
Try to always have a peek at enemy HP for your Ultimate: Finales Funkeln. It's a finisher if they flee, if I ever saw one ( can also be used once at their doorstep, fleeing to their fountain to some NICE effect) Also, get the blue buff. Near the end, this means your Ulti will be ready every 24secs... 24!!!! LAZA POWAA
Try this build and tell me how it works for you.... I haven't lost with this build yet
IMPORTANT NOTE: try to sprinkle in some MANA Pots here and then because she sucks it up like crazy.
