Lux is a ranged, Mage champion only costing 3150 IP/ 790 RP. She has a very high ability Power ratio which means she can deal heavy amounts of damage to her opponents. Lux is NOT a tank, you should be behind your team in team fights; shielding the tank, applying AOE damage with your E and binding opponents to initiate a fight.

As lux early game is very simple. Farm, Poke, Roam and Repeat. You should not roam if you are behind in Cs because it will put the opponent on a Cs lead which may become devastating late game. As lux you should not be risky by playing very aggressively since you are very squishy. If you do decide to play aggressively you have your Barrier in case things get ugly. Once you hit level 6 you have a huge power spike, you now have the ability to one shot (combo) an opponent since you trigger thunderlords and your passive. Your ult is also good for sniping an opponent.

Push out lanes but make sure you ward so you don't get caught out. Stay with your team afterwards so if a team fight does occur your abilities will benefit heavily to winning the fight.

STAY WITH YOUR TEAM!! Late game you are a target since you are squishy and a threat to most champions, therefore having your team with you should make it more safer.

If you want to be good at lux here are a few tips:

1. Make sure your farm is consistent

2. Once you land your bind on a squishy target perform your full combo because it is likely that person will die

3. Yasuo's W does not stop your ult

4. Practice, understand how much damage each ability does because late game it is easy to miscalculate and end up over killing your opponent or have your opponent creep up to you after your combo seeking out revenge.
