[12.2] β™₯ Lunar Rabbit Leader | DatKawaiiBunny's Lux Guide

By DatKawaiiBunny

Welcome to my sensation Lux support and mid-lane guide! I hope this guide helps you on your journey to learning Lux, The Lady of Luminosity. In this guide, I will be going over pros & cons, runes, abilities, items, spells, and gameplay tips. If you have any questions, I would love to help! Just leave them in the comments. Also, if you have any concerns, feel free to message me!If you're curious, I started making a to-do list for my guides. You can check it out below in "Ending/Credits".

This guide is based on my experience playing Lux. I will mainly be focusing on support but I will add some mid-lane runes and items. Some of the runes/items might be repeated because I take them for both mid and support.

β€œIn the name of Demacia, I will punish you!”

Hello, I'm DatKawaiiBunny! I'm a Gold IV ADC and support main. I've been playing League of Legends since April of season 7 as an ADC main, specifically a Caitlyn main. My overall goal is to climb to platinum. My highest mastery champions are Lux, Caitlyn, and Xayah. I usually stream 3 times a week, and upload clips to Youtube, so come and say hi, or ask me questions about Lux.

Lux is my most played champion with over 500k mastery points. She has been my go-to support in ranked for years! Lux support has it all. Crowd control with Light Binding, a shield with Prismatic Barrier, and a fantastic ultimate that could be used in teamfights, Final Spark. I update my guide each time I play her with items, runes, etc. I really appreciate you guys taking the time to read my Lux guide. Thanks a lot, and happy supporting!


β™₯ Long Range

β™₯ Lots of AOE/CC

β™₯ High AP Damage

β™₯ Good Shield

β™₯ Low Cooldown on Final Spark

Lux is quite a strong support. She has a little bit of everything, range, damage, and sustain. Her Q Light Binding can root two enemy units at the same time, and her E, Lucent Singularity slows all enemies that are standing in the circle. Not only that, but she has a pretty good shield, Prismatic Barrier that can shield yourself and allies twice. If you're going full AP Lux, you will do a lot of damage with your abilities, especially with Final Spark. It deals the most damage and has a low cooldown mid/late game.

β™₯ Squishy

β™₯ Mana Problems

β™₯ All Abilities are Skillshots

β™₯ Long Cooldowns Early

β™₯ No Mobility

Of course, Lux has some problems. She's a very squishy champion throughout the whole game, especially at level 1. Without runes/items, her health is at 490 and she has 19 armor. Her abilities are all skillshots, even Prismatic Barrier, so she requires a bit of practice. Also, she has a little bit of a mana problem. Make sure to not spam your abilities too much.

Arcane Comet
Out of all of the runes, Arcane Comet is the best rune for Lux support. Damaging an enemy champion with an ability hurls a comet at their location, dealing 30 - 100 (based on level) (+ 20% AP) (+ 35% bonus AD) damage. If Arcane Comet is on cooldown, the remaining cooldown is reduced.

Summon: Aery
If you're going full support Lux, I suggest taking Summon Aery. Your attacks and abilities send Summon Aery to an target. It deals 10 - 40 (based on level) (+ 10% AP) (+ 15% bonus AD) damage to enemies and shields allies for 35 - 80 (based on level) (+ 25% AP) or (+ 40% bonus AD) damage.

Manaflow Band
Manaflow Band is the best option for Lux because she uses up a lot of mana early with Lucent Singularity. Hitting enemy champions with a spell grants 25 maximum mana, up to 250 mana. Upon earning 250 mana, Manaflow Band restores 1% of your missing mana every 5 seconds.

Transcendence is the perfect rune for AP and enchanter Lux support. When you reach level 5 and 8, you will gain 5 ability haste. At level 11, on champion takedowns, your basic abilities (everything except Final Spark) will be reduced by 20%.

If you would like to deal more damage, specifically during the early game, take Scorch. Your next damaging ability hit deals 15 - 35 bonus magic damage (based on level) after 1 second. You can also Gathering Storm for mid-late game damage. Every 10 minutes, you gain 8 AP.

Biscuit Delivery
At 2, 4, and 6 minutes, you will receive a Total Biscuit of Everlasting Will. Consuming a biscuit will instantly grant 50 mana and permanently increase your maximum mana by 50. This is a great early game rune since Lux uses up a lot of mana because of Lucent Singularity.

Cosmic Insight
I highly recommend this rune for enchanter Lux. Cosmic Insight gives you 15 summoner spell haste and 10 item haste, so this will go nicely with active items, like Redemption and Mikael's Blessing.

Perfect Timing
Perfect Timing definitely comes in handy, especially if they have assassins, such as Zed or Kayn. At the start of the game, you have a Commencing Stopwatch. At 14 minutes in, it will turn into a regular Stopwatch. However, takedowns reduce the cooldown by 2 minutes. Also, the item contributes 250 gold towards Zhonya's Hourglass.

Presence of mind
Since Lux has a bit of a mana problem, Presence of Mind will help. Damaging an enemy champion increases your mana regeneration by 1.5 βˆ’ 11 mana per second (depending on level). However, it is reduced to 80% for ranged champions. Enemy champion takedowns restore 15% of your maximum mana.

Coup De Grace
If you're going full AP Lux and/or taking Dark Harvest, this is a great option. When champions are below 40% health, you deal 8% more damage. ( Dark Harvest appears when the champion is below 50% of their max health.)

Ability Sequence
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

β™₯ Passive: Illumination

Lux's damaging spells charge the target with energy for 6 seconds. Lux's next attack ignites the energy, dealing 18 - 190 (at levels 1 - 18) (+20% of ability power) magic damage to the target.

β™₯ Light Binding

Cost: 50
Cooldown: 11 / 10.5 / 10 / 9.5 / 9

Lux throws out a skillshot that immobilizes 80 / 125 / 170 / 215 / 260 (+60% of ability power) magic damage to up to two enemy units for 2 seconds.

β™₯ Prismatic Barrier

Cost: 60 / 65 / 70 / 75 / 80
Cooldown: 14 / 13 / 12 / 11 / 10

Lux throws a projectile that shields her and any allies hit for 2.5 seconds. They are granted a 45 / 65 / 85 / 105 / 125 (+35% of ability power) damage shield. After Prismatic Barrier reaches max range, the shield comes back and shields Lux and any allies for the same amount. The second shield stacks with the first shield while also refreshing the shield duration.

β™₯ Lucent Singularity

Cost: 70 / 80 / 90 / 100 / 110
Cooldown: 10 / 9.5 / 9 / 8.5 / 8

Lux throws her ability in a targeted area, which slows nearby enemies by 25 / 30 / 35 / 40 /45% and .25 seconds. The zone lasts 5 seconds and can be reactivated. The ability deals 70 / 120 / 170 / 220 / 270 (+70% of ability power) magic damage. Enemies that are damaged by the Lucent Singularity are slowed for 1 second.

β™₯ Final Spark

Cost: 100
Cooldown: 60 / 50 / 40

Lux fires a laser that deals 300 / 400 / 500 (+100% of ability power) damage to all targets in the area and reveals it. It ignites and refreshes Lux's Illumination debuff if it hits enemies already afflicted. Lux can Flash while using Final Spark. Her ultimate won't follow her when she Flash.

Flash teleports your champion wherever your cursor is. Flash is a good engage and escape tool for Lux. You can Flash then use Light Binding. It's also a key spell for all champions, except Yuumi.

Heal is a pretty standard bot lane spell. However, your ADC usually takes Heal. If they don't, I highly recommend you do. It heals you and the closest allied champion to your cursor (or the most wounded ally if no target is near the cursor) by 90 - 345 health and gives you both +30% movement speed for 1 second.

Ignite deals damage 70 - 410 true damage on a targeted enemy champion for 5 seconds and applies grievous wounds, which reduces all healing received and regeneration rates by 40%. Ignite helps in teamfights and against champions that heal, such as Dr. Mundo and Vladimir.

On a rare occasion, take Barrier for more sustain. This helps against counters and poke champions, such as Zyra or Thresh. Barrier shields your character for 95 + (20 per level) for 2 seconds.

Exhaust slows down a targeted enemy champion for 30% of their movement speed, and reduces their damage by 40% for 2.5 seconds. Exhaust can make engaging easier, mostly because Lux can root up to two enemy units with Light Binding and slow enemies within a target area with Lucent Singularity.

Support is one of the most important roles. There's more to it than just playing the champion. You have to understand your job in the laning phase, teamfights, as well as warding, and wave control.

Lux's job in lane is to harass the enemies and set up opportunities for yourself, your ADC, and/or your jungler. Don't be afraid to get kills because you need gold. AP items are expensive. If you are able to pull off a combo, do it. However, don't purposefully take kills. Your ADC needs gold too.

β™₯ Level 1:

You just want to get level two. Preferably before the enemies level up. Your job is to set the tone for the lane by either being aggressive, or passive.

β™₯ Level 2:

Not only does it depend on wave control and lane pressure, but it also depends on which support item you bought. I only recommend taking Spellthief's Edge because you won't mana regeneration with Relic Shield.

β™₯ Level 3 - 5:

Level 6 is when you get your ultimate, which is your strongest ability. Before then, your job is to get as much money as possible and to provide pressure so you can get objectives, like dragon and first turret . As Lux, you should be aggressive, but not reckless.

β™₯ Level 6:

Now, you have your ultimate, Final Spark. You can now burst down the enemies with a standard Q + E + R + E (recasted) combo! Your ultimate can also come in handy if your team is trying to steal the dragon .

β™₯ Roaming:

Personally, I like to roam after I get to level 6, but you can roam sooner. This is where you really have to communicate with your teammates. Roaming is also a great opportunity to deep ward, ward the river, or ward objectives, like a dragon. Lux has good roaming because of her root and ultimate. Some good times to roam are when:
  • You and your ADC recalled and the wave is pushed bot lane
  • Mid has priority, so you can help get the tower
  • Your jungler is ganking mid. You can most likely 3 v 1 or 3 v 2.

β™₯ Teamfight Tips:

Teamfights are very important. They can easily turn the game around. Lux has the perfect kit for teamfights. Light Binding can root two champions, Lucent Singularity can slow and damage multiple champions, along with her ultimate, Final Spark. Make sure to peel for your ADC and stay behind your frontline. Shield as many allies as possible, especially if you're going enchantress support Lux. Sometimes, you can steal dragon with Final Spark. You usually deal enough damage mid/late game. ( Chilling Smite and Challenging Smite deal 900 true damage.)

β™₯ I would like to thank everyone for reading and voting for my Lux guide! I hope my guide helped you along your journey. I try to make these simple so they can help a wide range of people.

Guides are usually updated at the start of a new patch and throughout the month, if I have time. I love answering questions and helping people, so feel free to ask as many questions as you want! Also, feel free to point out typos. I find some from time to time.
