NOTE: Please do not vote on my build unless you have thoroughly read through and/or tested it yourself. I spent a lot of time perfecting the gameplay and writing the guide and do not want uneducated critisism. However, constructive critisism and suggestions are welcome and appreciated.

Hello, and welcome to my Lux build. In this guide, I am going to explain how to play Lux using high amounts of Ability Power and an excellent amount of Magic Penetration. This combination, matched with expert use of her Crowd Control abilities, and her Passive, will make even the most beefy tank crumble before your power. Anyone without massive Magic Resistance is technically be taking true damage from all of your abiities. Even with powerful defense items like Force of Nature and the like, the opponent's Magic Resistance will be next to nothing and quickly drowned by the respectable amount of Ability Power you will have accumulated.

I will be explaining how to use Lux for the middle lane because I feel she has excellent potential to gank with her almighty ulti, the Gundam Beam (yes, I'm going to call it that through out the entire guide).

I personally do not like to see builds that have each rune type affecting a different statistic. I consider it to be too small of a boost to make a noticeable impact. There for, all my chosen runes are set towards given the extra OOMPH to Magic Penetration. Seeing as Seals cannot commit to Magic Penetration, I have dedicated it to Mana Regeneration to give a small, but humble bump.

This build features a basic Mastery Tree for Lux, putting nine in Offense to get the extra 15% Magic Penetration. The other 21 points is placed typically, but logically into Utility to help with Mana Regeneration, and the cooldown of your Abilities and Spells. With Intelligence and Sorcery, that alone is a 9% Cooldown Reduction for your Abilities. It is also highly important that you put the two points into Utility Mastery, as you will be grabbing the blue buff often to make up for weak Mana Regeneration.

To maximize your damage potential, it is important that you utilize all your abilities (passive included) in the correct order when going toe to toe with a full HP enemy.

This is the attack order I tend to use:

Light binding > Basic Attack > Lucent Singularity on the opposite side of the opponent > (Ghost if you can to help chase) > Disperse Lucent Singularity > Basic Attack > Finales Funkeln

This is the part that most people will pay attention to, possibly even ignoring all other aspects of this guide, however it is important to note that this item build is perfectly matched with the Runes and Masteries listed above. And without further adieu, let the main event of the guide begin...



Start off the game by immediately grabbing Boots of Speed, a Health Potion, and TWO Mana Potions (You're going to need them), then head for the middle lane. I choose to start off the match with these items for numerous reasons:
1. The extra Movement Speed is beneficial to your passive, as you should almost always try to move in to make that basic attack in once you've successfully landed your Light Binding.
2. It will help you to back off as soon as you've executed your passive, potentially preventing your enemy from poking you.
3. If the opportunity to gank the top or bottom lane is presented, you will reach the lane faster.
4. You will burn through the Mana potions fast, so purchasing Boots of Speed leave you enough money to buy two potions instead of one, increasing your time in the lane. (If you feel confident that you won't be harmed much, grab three Mana Potions and ignore getting a Health Potion)

Try your best not to stand opposite of the enemy champion in terms of where the minions are, as there are usually more minions blocking you of your target champion. Standing parallel more often keeps only one minion between the two of you, enabling your Light Binding to hit the champion (as it will hit the first two targets in its path).

Continue to dwindle HP with your Light Binding and Lucent Singularity. If the opportunity presents itself early enough, signal a suitable teammate to wait in the nearby brush to gank, giving the signal to rush out once you lock the champion in place with Light Binding.

When your remaining mana reaches about a third of it's capacity, use your Clarity spell BEFORE using your Mana Potions. This is suggested because it will only recharge your Clarity Spell earlier for the second time you use it before returning to base. Through experience and multiple tests, I've concluded that moderate harassment and use of Clarity before Mana Potions will enable you to use Clarity again right as you are achieving your first rank of your Ulti often taking your opponent by surprise when you pop Clarity and nuke them with Light Binding>Basic Attack>Lucent Singularity BEHIND the opponent (as they will more than likely try to run> Basic Attack>Gundam Beam>RAPE.

You will want to use your Mana Potions AFTER the first use of Clarity but BEFORE the second use. It will enable you to keep a steady pace of offense against your opponent.

As a rule of thumb, try to stay in the lane until you have executed your first attempt at nuking your opponent with your Q, E, and R. Assuming you knew what you were doing and the enemy champion was obliterated, recall back to base and purchase you Mejai's Soulstealer.

As the end of "early game" draws near, your main objective will now be to farm minions, control your lane, and most importantly, GANK WHENEVER POSSIBLE. You need stacks to make this build work. Lux is excellent at ganking with her remarkable combination of Abilities, (bind, slow, and a long range, high damaging Beam of Death) so do not be discouraged! Get those Stacks, and finish your Sorcerer's Shoes and Haunting Guise to add Magic Pentration, AP, and more Movement Speed.

As the first turret inevitably falls, say hello to Mid Game.

By now, the enemy team should be wary and quick to retreat when you unexpectantly show up in their lane, mocking their pathetic Magic Resistance and dealing true damage. Continue your killing spree and farm minions because your next three items are costly and will take a while to achieve.

Once your level hits double digits, you should have your Void Staff. Work on getting the blue buff from the Ancient Golem whenever possible. Your poor Mana Regeneration is your biggest flaw, but with Clarity and continuously refreshing your blue buff, it shouldn't be that much of a problem.

Team fights are now starting to form, so when they do, keep to the back of your team and out of harm's way. Lux is very squishy but she makes up for it with the range of her Abilities. Always try to get the killing blow on the enemy champion, but in situations that being the final assailant isn't possible, do your best to do ANY damage no matter how little to the opponent before he/she dies. Two stacks is better than one; however, one stack is better than none.

It is important to note that you should try to avoid using your Gundam Beam unless it is to kill an opponent. You will be dealing somewhere between 600 and 800 damage with this ability alone with all your items by late game. It isn't fun to initiate a battle with your Ulti, damage them with your other abilities or having an ally deal damage, only to have them running away with no way of stopping them in their tracks. The Gundam Beam is the final blow, the overkill, the death-dealer of light. Use it accordingly.

By now, you should have, if not close to finishing the Rabadon's Deathcap. Things are getting intense, there have been battles everywhere, people are complaining that the Ancient Golem is always dead, enemies are afraid to over-extend, and most rewarding of all - you do massive amounts of damage now...

You may have been the King of the Rift in Early/Mid game, but be cautious now. Other champions are completing their builds as well, and any Summoner that knows what he/she is doing will be just as dangerous as you are.

Your main focus now should be to push down turrets with allies, utilizing your Sheen/Lich Bane with your passive for OMEGA basic attack damage, and providing support, both offensively and defensively, in team fights. Do not forget, now that late game has arrived, you now have Prismatic Wave to protect you and your allies with when the fighting gets too heated. It will shield anyone it passes through for a few seconds when it extends AND retracts, so try your best to keep your allies between you and your outgoing shield. Doing this will shield them TWICE upon its return. Keep it in mind, it can save lives by a thread.

Solo-ganking now becomes a rare opportunity AND a risky one, as champions start to travel in packs, baiting with their squishy champiion(s), while the rest of the team waits in the brush. Keep an eye on your map as you trudge to your destination. The jungle is going to be increasingly more dangerous now due to enemies constantly changing lanes, so take a ally or two with you when you refresh your blue buff. You can almost always guarantee getting the death blow on the Ancient Golen with propor timing of your Lucent Singularity Ability.

To be clear, I'll highlight key things to remember:

Fight from a distance. You have excellent range, utilize it.

Gank Early/Mid game to get your stacks snowballing.
Get the Blue Buff to help with Mana Regeneration
Stay behind your allies in team fights.
