[2.3] Lux Guide - Dr. Curvy's Guide to Lux Support [In-Depth + Vid]

The starting items for Lux will be different. It will depend, if you are wanting to go for an AP Lux or Enchanter Lux support build.

For your starting items on Lux (AP), you can either take Amplifying Tome  or Ruby Crystal . But that depends on how your playstyle is within the early game;

• If you are aggressive in lane, take Amplifying Tome  
• If you are passive then in lane, take  Sapphire Crystal , the extra mana would be beneficial for poking in lane with your Lucent Singularity at Level 1.

For your starting items on Lux (Enchanter), you can either take Amplifying Tome  or Ruby Crystal . But that depends on how your playstyle is within the early game;

• If you are aggressive in lane, take Amplifying Tome  
• If you are passive then in lane, take  Ruby Crystal , the tanky stats will help if you are getting poked early.

This will be built in to an early Ardent Censer , as your first item.

But you can either choose Ardent Censer or Harmonic Echo  (when you are going Enchanter), but that depends on these factors:

Ardent Censer as a first item will usually depend on who your ADC is, champions like Jinx , Vayne or even [kaisa] would benefit from this. The reason is because you and your ADC gain attack speed, as well as on hit (bonus) magic damage for 6 seconds. Make sure to take advantage of it!

Harmonic Echo as a first item will benefit from champions that are very aggressive in the early game (a.k.a Lane Bully). Champions like Draven , Miss Fortune and even Jhin would benefit from this because it heals you and your ADC at 100 stacks, so don't be afraid to trade in lane once you see this item at maximum stacks!

When it comes to AP Lux however, you would defintely want to get Luden's Echo as your first item. This is good because you deal tons of damage with your abilities, and the enemy will get scared of your damage and may not try to trade. 

Your second item will be the Awakened Soulstealer . Each unique takedown grant you 3 Ultimate Haste, which will cap out at 15 Haste! Add on top of that your Ionian Boots of Lucidity , you will be spamming your ultimate like crazy!

Third item for me, is usually where I choose my boots & enchant considering the active is crucial to a mid-to-late game teamfights. I am here to breakdown the boots you should get, to know what is a must-buy;

• Ionian Boots of Lucidity is the boots I usually get when my whole team and I are snowballing. Having more Ability Haste means you are able to spam out your spells even more. Remember Ability Haste has no cap, so spam them abilities like it's URF.
• [Ninja Tabi] is when the enemy team has a fed AD Assassin or ADC that you don't want to mess with. Also if you need to survive, for when you need to be there for your team. This item will be useful for champions like Zed or even Yasuo .
• Mercury's Treads is for when you are against a bursty support like Lux (yourself) or Seraphine , It also comes in handy when you are against the AP Assassins like Akali , Evelynn , Fizz & Kennen . Also Mercury's Treads reduces the amount of CC (crowd control) time dealt to you.

Which Boot enchant should you get?

Got your boots? Now what enchant would you go with? Here are a some suggestions;

• [Locket Enchant] is SO USEFUL! I am so surprised that no one uses this enchant often, especially the support players out there (Tank Baron Laner's can benefit from this too.) Giving your shield an AOE shield that can probably save everyone is
  kind of broken, add on to Lux 's [lux:2] then your team will positively survive those late game teamfights for Baron or Elder Dragon. Just make sure to POSITION properly, an enemy assassin or enemy jungler can easily focus you down, especially when Flash is on cooldown.
• Redeeming Enchant is so UNDERRATED. I started using this recently on my match games as Lux and may I say it is a lifesaver. For Lux she barely has a healing skill, but pairing her with the items I recommended and this enchant...you will leave the fight probably around 70% health. I love this item! I simp for this one.
• Shadows Enchant is probably that enchant where the game recommends you to get, but compared to others this is the least efficient enchant - for me anyways. See by the late game you would probably have your Sweeping Lens that is way more efficient, as well as using the vision plants that is around the jungle. However, scouting out where champions are with the shadows will come in handy and give a sense where majority of their team is. But the slow will be useful for you to catch them with Light Binding .

For you 4th & 5th item could be situational and it all depends on you, here are some items that you might want to add to your build:

ENCHANTER (LUX)

• Athene's Unholy Grail for even more healing. You will be surprise how much healing you can do once late game hits.
• Zeke's Convergence is a tremendously powerful item! Not only does it bring the armor and magic resistances to Lux , but it also bring a buff that increases the attack of the highest AD in the game for 2 seconds whenever you cast your ultimate.
• Protector's Vow This is very useful when there is a lot of assassins trying to take you or your ADC down. The shield can be triggered whenever a champion, monster, or even a turret hits you, both you and an ally next to you will get the shield. Don't forget more armor stats so that you can survive! Useful in all AD team comps.
• Adaptive Helm This is probably my secret favorite item. Especially when you are faced with an annoying Kennen , Teemo , Orianna and Akali . Reduces the magic damage of the same ability for 15% for 4 seconds! That's enough to shut down, any annoying AP threat. Hell, even AP Malphite . If you are faced with pure AP team comps, this is a must buy after your core.
• Rylai's Crystal Scepter this item will help you to catch up to people at the late game, the slow on it's passive is so powerful with you Lucent Singularity , that you can snipe someone with Final Spark if they enemy ever survives your ult, which they don't.
• Thornmail  for the enemies who build lifesteal like Master Yi , Darius and even Draven . Anti healing is a must, so that you can win these fights. It will be a big deal, within the late game.

AP (LUX)

• Morellonomicon for the enemies who build lifesteal like Master Yi , Darius and even Draven . Anti healing is a must, so that you can win these fights. It will be a big deal, within the late game
• Rabadon's Deathcap for more bursting power! You can hit and use Final Spark and snipe them haters.
• Void Staff for the enemies who started building magic resist.
• Rylai's Crystal Scepter as I mentioned above, this item will help you to catch up to people at the late game, the slow on it's passive is so powerful with you Lucent Singularity , that you can snipe someone with Final Spark if they enemy ever survives your ult, which they don't.
