Lux's Skills
Lux is a great poker, but also strangely good at bursting enemies out of nowhere. When you encounter an enemy, do the following burst order.
Light Binding > Basic Attack >
Lucent Singularity > Finales Funkeln > Basic Attack. If they are still alive, they won't want a piece of you and they'll run. If they do come at you, throw out your
Prismatic Barrier and wait for your cooldowns to come off. Then do it again. (Minus your ult)
Her passive,
Illumination is great for farming minions and poking at enemy champions. It also is great for doing damage to enemy champions late game, as it gets stronger every level. Pretty much you hit the target with
Light Binding,
Lucent Singularity, or Finales Funkeln and it applies the "mark". Follow up with a basic attack and they take increased damage.
Tips: If the target has a mark on them, Finales Funkeln procs the mark, doing damage, and reapplies it. Keep that in mind as they are trying to recall under the turret.
Her Q,
Light Binding, is one of the best snares, if not the best snare, because it affects 2 targets in the line. Keep in mind that this is a SNARE, meaning NOT A STUN, meaning they cannot move, but can still cast spells at you, basic attack you, and what ever they want as long as the ability doesn't lead to them moving.
Tips: This will snare 2 enemies, which is great when trying to run, or as someone else is running too. When in lane and you snare the enemy champion, follow up with basic attack >
Lucent Singularity > Basic attack. Getting the 2
Illumination hits off really maximizes damage.
Your W,
Prismatic Barrier, is useful in the sense that you can shield yourself and allies twice. Why I pick it up at level 1 but not max it first or second is because Lux in this build is an AP Mid, and is also a Mage, not bot support. It is nice to have though so that you can get an easy assist by shielding your teammate as the chase someone or to save yourself or a teammate from exhaust.
Tips: Try to get easy assists by using it on a teammate as they are chasing for a guaranteed kill. Also, use it constantly to block the damage of
Ignite or any other DOT abilities, or use it when getting blue or a huge minion push.
Lucent Singularity does fat damage to enemies in a circle and slows them. But it also reveals the fog of war when you place it and slows enemies inside the circle.
Tips: When getting Dragon, blue, or Baron, put this bubble in the place you think the enemies will come from, slowing them down and doing damage to them. Place it in a bush to see if an enemy is in there to prevent walking into a gank. Place it on the back minion line and explode it, then basic attack them for easy farm. Remember that it takes time to travel to the target destination.
Your Ult, Finales Funkeln deals damage in a straight line, revealing the fog of war and damaging all enemies in its path. And it has unreal range!
Tips: There are many uses for this ult, whether for damaging enemy teams, picking up easy kills under the turret on low health enemies, or seeing if they are at baron or dragon. But the best one is taking buffs. Place a ward around the enemy team's blue buff once you reach level 6 and have your ult. When you notice they are getting it, get in range of it and wait till it gets low health. When it does, ult that ish and get back. When you take it, who ever was taking it will come for you, so just wait a minute. Make sure to say "lol" when you take it too.
Items
The item focus that I am trying to emphasize is that Mages need to cast spells. Most mages, Lux being one of them, need mana to cast these spells. Lux, being one of these mages, has a high mana cost. So I will explain all of the possibilities. Also having high damage output through AP is essential too, and the mana items are actually more damaging than you may think.
Early Game/Mid Game Items
Tear of the Goddess- Great item, really gives the maximum mana we are looking for. I recommend getting this before boots if you can, but if you go back and it came down to getting a mana crystal or boots, get boots. This is crucial to get ASAP because then you can start stacking the mana quickly. This item also correlates to the second highest AP item in your build.
Chalice of Harmony- Absolutely great and fat mana regen, really gives you the mana sustain that you need. Even if you are at minimal mana, you will regen enough so quickly that you can easily get a spell off. I used to hate this item on Lux. Why? Because there was nothing to build it into. But, now that there is, I incorporated this item into my build immediately. Plus, the MR is perfect against another AP Mid that you are probably up against.
For boots, we will be looking at 2 different pairs. On one hand, you can buy the
Ionian Boots of Lucidity, which is what I always get. But yet some people still prefer
Sorcerer's Shoes, which do give you MP, but I just feel that is something you dont need, as opposed to getting CDR, which
Ionian Boots of Lucidity give you. Especially because this is the only CDR item I get in correlation to the
Athenes Unholy Grail.
Athene's Unholy Grail is unreal good, especially because they buffed it a little bit in that last patch. Now you are looking at 90 AP, 40 MR, 12.5 Mp/5, and a 15% CDR. And 2 great mana restoring passives. Now you may say that "this comprimises damage for mana!" and my answer to that is 90 AP? That is the 4th highest AP item in the game, but if you do not have mana, 3rd, as
Archangel's Staff would only have 45 then(But who wants this that has no mana?) Plus, this item pretty much has a built-in
Negatron Cloak
Highly Important Items
Rod of Ages is a great Health, AP, and Mana giving item, helps your damage output, especially when fully stacked, plus you get 630 Health when fully stacked! And the passive level up bonus is just great, it really is. And the extra Mana doesn't hurt either.
Archangel's Staff Is the second biggest AP item in this build, but really helps in mana regen and maximum mana. I mean, 1350 mana? That's an unreal amount. And, you can actually tell how much AP you get from it now, and I get over 150 AP with the 45 added. That's more than a
Rabadon's Deathcap! But the Rabadons does have the UNIQUE Passive of 30% more AP, which is always nice to have in your arsenal. The
Rabadon's Deathcap is just, to put simply, the most important item for getting lots of AP. Mix this with pretty much unlimited mana and lots of CDR, and you have a got a devastating blow.
Last Item to Get
Void Staff A great item, I tend to get this when they have too much MR for me to handle and cannot deal sufficient damage.
Will of the Ancients I don't ever get this, especially because its more expensive now, but you just don't get enough health from it. Because you only get 1/3 of the 20% of the damage you do, you get very minimal health back, especially in team fights. Why only 1/3? Because all of Lux's spells are multi-target. But if you feel it will help or you wanna support your team with it, go ahead.
Abyssal Scepter is great for countering an AOE person, such as
Karthus or
Cassiopeae or
Amumu (Don't get this to counter a
Veigar, he will still burst kill you with ease) and also does help in making a squishy suddenly a whole lot squishier.
Deathfire Grasp Is a great option, especially if there is a really fat
Gragas or a demolishing
Cho'Gath that need to lose a lot of their health. Also gives CDR, which will put you over the cap, but also brings you to the cap. And gives you another spell to use.
Lich Bane Great item, Passive stacks really well with Lux's Passive. Some more MR, and really gives your basic attacks a BAM! And more Mana too, which gives more AP (But minimal from that)
Zhonya's Hourglass More AP and lots of armor, with a great passive that lets you take all kinds of abuse with no damage being taken. Try to utilize it to counter a
Karthus
Requiem or a
Fizz
Chum the Waters
Banshee's Veil is great against a
Veigar that eliminates you from the fight before you knew what happened. It will block a spell and reduce all the others damage. Plus health and mana are always welcome, as is some extra MR.
Maybe a second
Archangel's Staff would be adequate. You get the 350 Mana plus the 45 AP plus the passive 3% mana to AP to. But you do not get the additional 1000 mana. This will really bump up your AP.
