[Mid] [9.14] Making Light Work of Climbing Elos

By unownreality
My name is unownreality. I've been playing since season 2, and Lux has always been my favorite champion to play. With an awesome lore behind her character and a fun kit, she became my main champion since season 5. I made gold in season 5, and platinum in season 6. Hit Diamond in season 7, and season 8. Happy to say right now, I am the in the top 200 Lux in NA. Lux enables me to help solo carry some games, and provide the utility my teammates need to succeed.

This will be my first guide, so bear with me a bit. Any questions, feel free to ask!

Guide Last Updated 7/17/19 for Patch 9.14

Pre-season and Mobafire guide appearance changes all in the same week! Yikes! Consider the guide a current work in progress while I adjust to preseason changes and the new mobafire setup. I'll include a new Chapter, Work in progress, to show the changes I make to the guide as I input them.

And please feel free to give feedback!

Runes! An explanation

Keystone Mastery

Electrocute is currently one of the strongest aggressive runes to take. Thankfully, it works out quite well on lux, and adds more potency to her burst. The only downside is the somewhat long cooldown.

Secondary Runes

Cheap Shot: When you use Light Binding on an enemy, this rune will allow you to deal bonus damage. Can also stack off Lucent Singularity when the slow is activated. Adds more potency to burst combo
Eyeball Collection: This will build up over time granting small values of ability power. However, feel free to swap to either rune if you prefer to have a vision preference in lane.
OR Zombie Ward/ Ghost Poro: Like I said before, if you feel vision is more important than the AP, feel free to go either of these. Personally, I think Zombie ward will do better in mid lane, and if you are roaming. If not, ghost poro in the river bushes help as well.
Ultimate Hunter: The new Ultimate Hat. Provides cooldown reduction on your ultimate. This rune is now more important on Lux since the reset mechanic on her ultimate is no longer as of 7/17/19

Minor Runes


I think its important to pause here and take a moment to look at why the suggested path is now Precision. We have seen the inspiration tree take several hits to what a lux would normally go. First it was the nerf on Stopwatch and then the small nerf on Slightly Magical Boots. With Patch 8.7, we see presence of mind gaining a huge buff, and all mages should take full advantage of that.
Presence of Mind: This is huge for Lux and all mages. Presence of mind fills the gap that was left by the removal of Morellonomicon's old passive. Restore mana on takedowns. As a sweet bonus for Lux players, the chance of 10% cooldown on your ultimate. That brings it down to 8-10secs on kills!

Coup de Grace: This is good on mages for the same reason mages exist. Long range fights, because we are squishy as hell. Most champions in game will have a higher HP than you, and this helps boost the damage. Chances are, you are already going to one shot those with less HP anyways.

Lux's Abilities
Lux's offensive abilities mark all affected enemies with light energy for 6 seconds. Her basic attacks and Final Spark consume the mark, dealing 20 - 190 (based on level) (+ 20% AP) bonus magic damage.
ACTIVE: Lux releases a sphere of light in a line that deals magic damage to the first two enemies hit and roots them for 2 seconds.
MAGIC DAMAGE: 70 / 115 / 160 / 205 / 250 (+ 70% AP)
ACTIVE: Lux shields herself and throws out her wand in a line, shielding allied champions in its path for 2.5 seconds. Lux's wand then returns to her, applying the shield to all allied champions it passes through as well as herself.
SHIELD STRENGTH: 100/130/160/190/220 (+0.6 ability power)

Lux now shields herself and fires the missile at the start of cast (instead of after the 0.25 second cast time). She is still rooted for the cast time.
Lux sends an anomaly of twisted light to the target area, slowing nearby enemies and granting sight of the area around it for up to 5 seconds. At the end of the duration or if Lucent Singularity is activated again, the singularity detonates, dealing magic damage to all enemies in the area.
SLOW: 25 / 30 / 35 / 40 / 45%
Magic Damage: 60 / 105 / 150 / 195 / 239 (+60% AP)

R: Final Spark ACTIVE:

After gathering energy for 1 second, Lux fires a giant laser in a line that deals magic damage to all enemies hit, briefly revealing them as well as the surrounding area.
MAGIC DAMAGE: 300 / 400 / 500 (+ 100% AP)
Lux Ability Breakdown & Tips

Passive: Illumination:

Illumination will greatly increase the chance of killing a minion into lane, and will allow you to farm minions in the early game. Late game, when combined with Final Spark and using your full combo, Illumination can proc 3 times in a single combo.
This is your make or break ability, and probably the most vital to Lux's kit. Hitting Light Binding can allow you to get off your entire combo and getting a kill. You can use Lucent Singularity's slow to help you land your Light Binding. You can use Light Binding in an invade, or to initiate a fight for your team. You can use Light Binding to pause a chase and escape to safety. The high cooldown of Light Binding means if you miss, you missed the entire opportunity to pick up a kill, or prevent your death. However, Light Binding has a low enough cooldown to wait it out for a short time before taking another shot. With max CDR, it will only take 6 secs.
Walk toward the direction of your shield to reduce the amount of time it takes to double up. Use this frequently when your team is fighting, or when moving through jungles.
Your main power, and your main source of poke. Lucent Singularity's range is large enough to poke without punishment, gain vision of bushes, slow the enemy in an engage, or help with your escape with its slow. You can use Lucent Singularity's slow to allow you to hit Light Binding. Use this ability to clear waves quickly. Particle speed as Morgana Q, and size of Morgana E. Try to predict where they will be, not where they are.
Finish off your combo with a potent ultimate. Be aware this deals far more damage than it has done previously. A simple QorE will apply illumination and likely end with a kill.
Items Breakdown

Starting Items: Doran's Ring Health Potionx2

Item Sequence

Doran's Ring 400
Health Potion 50
This is your starting build. You could technically start a dark seal, but you will sacrifice the mana sustain. Lux's abilities cost a decent amount of mana, so the ring is a better choice.

Winning Lane: Needlessly Large Rod Dark Seal

Item Sequence

Dark Seal 350
Needlessly Large Rod 1250
Blasting Wand: You're probably asking yourself, why ruin your sustain in lane by sacrificing a Lost Chapter in favor of just ability power?! Well, if you are winning lane, the damage provided by Blasting will allow you to force out your opponent and punish their attempts at farming. You will suffer in mana sustain, but if you can farm effectively, and prevent your opponent from farming and pick up a kill, the delay of the Lost Chapter will be worth it.

Dark Seal: If you are picking up a few kills and assists, consider picking up a Dark Seal. Only upgrade to a Mejai if you are at 10 stacks.

Losing Lane: Null-Magic Mantle Seeker's Armguard

Item Sequence

Null-Magic Mantle 450
Seeker's Armguard 1000
Null-Magic Mantle: Note: As of 7.9, you do not want to build a Negatron Cloak. If you find that you still need the magic resist to help you win lane, it is okay to rush a Null-Magic Mantle into Banshee's Veil.

Seeker's Armguard: This will help against AD assassins like talon. Don't rush into a Zhonya's Hourglass or you will have trouble sustaining mana in lane.

Ideal First Buy: Lost Chapter

Item Sequence

Lost Chapter 1100
This will help solve your mana problem from the high ability costs, while providing a decent amount of ability power. This item is vital for playing mid lane, and should be your priority for your first back.

Core Items: Sorcerer's Shoes Luden's Tempest Morellonomicon

Item Sequence

Sorcerer's Shoes 1100
Luden's Tempest 3200
Morellonomicon 3000
Sorcerer's Shoes: Ideal for a mage like lux. Mana penetration. Need I say more?

Morellonomicon: The new Morellonomicon is even better than before, but at a cost. It no longer grants mana on kills or assists. In it's place, it picks up magic penetration (Which is still very strong as of 8.4)HP, and grievous wounds on ALL targets! Goodbye vlad hard counter!

Luden's Tempest: DON'T RUSH THIS ITEM! Hold onto Lost Chapter until the end of laning phase. Helps your clear the back line of minions and increases your poke drastically. A large amount of ability power. Now also provides mana!

Final Build (in addition to above items): Void Staff Rabadon's Deathcap Spellbinder

Item Sequence

Void Staff 2800
Rabadon's Deathcap 3600
Spellbinder 2900
Spellbinder: This item is a bit tricky to use, but could give you a better chance at catching out a target. Pop this if you notice that you are in trouble and need a burst of speed to escape. Try to hold onto it though for your burst. If you launch a Q within two seconds of popping it, you will have the additional ability power available for your burst.

Void Staff: Magic Pen to make abilities hurt more, and a decent amount of ability power. Should be a priority buy.

Rabadon's Deathcap: This is going to give you alot of power. I would only get Rabadon's after level 16, when your ultimate gives you a large damage boost. This will allow you to one-shot anyone with 1500hp or excessively squishy.

Zhonya's Hourglass: This item is a must against some champions. I reccomend rushing this on a matchup against a fizz, or a zed, as both have ultimate with the capability of one shotting you, but has time before it does so.

Other Cool Awesome Items for Lux: Mejai's Soulstealer Lich Bane Elixir of Sorcery Banshee's Veil

Item Sequence

Mejai's Soulstealer 1600
Lich Bane 3000
Banshee's Veil 2600
Elixir of Sorcery 500
Mejai's Soulstealer: This item is very useful if you invest in a dark seal early and reach 10 stacks fairly quickly, or if you are playing against a primarily squishy team. If you buy Mejai's Soulstealer, you should keep it at a minimum of 15 stacks at all times. Consider selling it if you fall below 10, and definitely sell it if you drop to 0.

Lich Bane: A fairly decent item for Lux, although there are better options. In order to pop Illumination you will have to auto attack after using an ability. This is the same functionality that Lich Bane provides. Good for an added burst, but you suffer in utility.

Elixir of Sorcery: This is the final pot you should take. Feel free to buy it as well if you are a little short on buying your final item. Don't buy any early game

Banshee's Veil: The new MR item for Mage's. Banshee's will improve the quality of life against other mages, as well as help save you from gank attempts. The new Banshee's veil brings with it the same base qualities as Abyssal Sceptre but the safe passive of the old Banshee's Veil into a perfect item for Lux.

Items to Avoid: Hextech items, Seraph's Embrace, and Hextech Items

Hextech Items: They don't work well with Lux's kit. At all. Avoid them

Seraph's Embrace: Sure more mana sounds like a great idea, but the long cool downs on Lux's abilities make stacking your tear agonizingly slow. Furthermore, You should have plenty of mana sustain late game with Morellonomicon. Oh wait, they updated it to no longer refund mana on kills or assists. Hmmm, this is awkward... Anyways, Seraph's is still a no go.
Farming in Lane
Here is where Lux struggles early game, and probably the reason she is not picked frequently in higher elos. She struggles to kill the caster minions with a single ability. However, with a lower cooldown and lower mana cost, you can quickly cast this twice to more effectively push your lane. Most of the time, you are going to have to combine Lucent Singularity with Light Binding to kill the caster minions. It takes just over a whole item to fully kill the back line of minions with an ability. Usually this takes just over 100AP for the first 10 mins to one-shot a fully maxed out Lucent Singularity.

On the bright side, this gets far better. After buying Luden's Tempest, you'll find you can clear the entire wave with Lucent Singularity. Whatever survives, you kill off by popping Illumination.

I find it useful to occasionally use Final Spark to clear a wave quickly if your opponent has roamed, or has gone back. With Lux's slow overall mobility, its hard to chase after them, so by clearing the wave, you force pressure onto the mid lane turret, and buy priority to then roam or go back and buy. The low cooldown of Final Spark should mean that by the time you get back into lane, the ability is off cooldown.
Lux's Wombo Combos

Lux's Poof Combo

The main combo to wipe off nearly anyone off the face of Runeterra is the following:
Q&E -> AA -> E -> R -> AA

That's just a bunch of words, so i shall explain. I recommend you start off fishing to hit your Q Light Binding. If you feel you are going to hit Light Binding, Launch Lucent Singularity immediately at your targets location, and launch an auto attack while the particle is traveling. Immediately after launching your auto attack to proc Illumination pop your e to refresh illumination and go into an ultimate. The ultimate will proc and refresh Illumination. If somehow your opponent is still alive, launch a final auto attack to deal the final Illumination blow. Your entire combo at full build can deal anywhere from 2,000-3,000 damage, depending on your opponents MR and Armor.

Can't catch me Combo

Getting chased and going to die? Use this!
E Hold & Expire -> Q

Let your E slow buy you distance. Just before he leaves the slow, detonate E and launch a Light Binding to insure your escape.

This is my Dragon/Baron/Buff

This will give you a burst big enough to challenge a smite.
E (hold)-> Q -> R

Use E to grant you vision of the buff. Depending on their kill speed, Detonate E, in time with the launching of the Q, and use your ultimate. The damage gives you just over 1k damage, and provides a challenge to securing the objective for the other team. Just the E hold alone, might scare them off.

Go Away Combo

To force someone away from the fight.
Q -> R

This combo will deal enough damage to scare them off the fight, and make their engage dirty. This combo keeps your main damage (E) available for the real fight.
Early and Mid Game
Focus on trading with your opponent, but keep an eye on your mana consumption. Lucent Singularity has a very high mana cost, but is also your best trading ability. Max Lucent Singularity first. Make sure to follow up with an auto-attack to proc Illumination.

If you are falling behind in lane, don't worry. Lux can farm pretty well under tower, and her q can ward off any potential divers. If you are ahead, force yourself on your opponent in lane. Lux is even a good champion to roam with. Her long range on the ultimate can execute champions who think they are safe, and with the new CDR on her ult if she gets a kill, the cooldown is well worth the attempt.

Lux isn't a great pusher, but she can clear waves. Focus on clearing waves to prevent the enemy team from sieging the tower. If a wave is pushing on another tower, the mobility on lux allows her to roam, clear the wave quickly, and get back before a fight breaks out. In addition, lux Q/E/R burst can steal dragon quite effectively. The combo deals more damage then smite, as long as her ult is level 2.
Late Game
Poke and get picks. Use Light Binding to catch off enemies, and have your team follow up if you can't or don't have the damage to burst them out. Watch when you use your ultimate. Be sure you are going to hit Light Binding before you launch Lucent Singularity and Final Spark. Many times, I fire my whole combo, only to find out that the hit box for Light Binding missed slightly. Now you have to deal with long cd timers, and your burst gone. This is prime time for enemy initiation.

Late game, you are the target. Stay in the back line, and use the range of Lucent Singularity to poke. Continuously cast Prismatic Barrier to protect the team against poke, or possibly, help with an initiation.

Lastly, don't focus the tanks. Lux does not kill tanks, and is most effective against the ADC, Mid, and Support champions. Although the malphite may be on top of your team, and your instincts say to use your abilities on malphite, You aren't going to do much to him. Land a light binding to kite them off, but not much more. Even if you do some damage to malphite, the high ability cooldowns is not worth the damage.
Lux is a strong champion if you use her correctly. She can have impactful in matches that are drawn out, and all it takes is a single Lux pick to win a match or teamfight. Lux is pretty easy to pick up, but takes a while to master.

Please for the love of God, don't waste Lux's talent on support. Lux was born a mage, not a mute string player.

Good luck Summoners!
