Lux ARAM Build and Guide

Updated for patch 26.21. Ability details come from Riot’s official game data for this patch; ARAM balance numbers come from the League of Legends Wiki’s champion data.

A Lux ARAM build has to work around three nerfs: in ARAM, Lux deals 85% damage, takes 110% damage, and her shielding is cut to 80%. Honestly, the kit still works there anyway. Light Binding, Lucent Singularity and Final Spark all hit an area or more than one target, and the Abyss is one lane with five people standing in it.

How do the ARAM modifiers change her?

Three nerfs, all stacked on her at once: 85% damage dealt, 110% damage taken, and shields at 80% of what they are on Summoner’s Rift.

You feel all three. Every Light Binding and every detonated Lucent Singularity lands at 85% of its Rift value, Prismatic Barrier blocks a fifth less, and the 110% damage taken is on a champion who has to gather energy before Final Spark fires. She’s still playable, to be fair. Which one would I watch? The shield nerf, because W is what keeps her alive when a team collapses on her, and 80% of a shield is the kind of number you only notice when you die through it.

Why does Lux’s kit fit the Howling Abyss?

Range and area damage. Lux has 550 attack range and four abilities she throws or fires at targets, and when all five enemies stand in one clump, her multi-target spells have more targets to hit.

• Illumination: damaging spells charge the target, and her next attack ignites it for bonus magic damage that scales with her level. Free damage on every trade, if you remember to attack.
• Light Binding: a sphere that binds and damages up to two enemies, on a flat 10 second cooldown at every rank. Grouped teams make the second hit easy.
• Prismatic Barrier: a thrown wand that shields any friendly target it touches. Cooldown 12 seconds at rank one, 10 at rank five. It’s 80% strength in ARAM, but it still covers everyone it passes through.
• Lucent Singularity: an area that slows, then detonates for damage. The cooldown drops from 10 to 8 seconds with rank, the shortest of her damaging spells.
• Final Spark: a beam that damages every target in its path, triggers Illumination and refreshes the debuff. Cooldown 60/50/40 seconds.

Thing is, her problem is anyone who gets on top of her. Nothing in the kit moves her (no dash, no blink), so once a melee champion reaches her the 110% damage taken finishes the job, and on the Howling Abyss there’s no second lane to rotate to. The clump that feeds her spells is also where the diver is standing until he isn’t.

What should a Lux ARAM build focus on?

Ability Power first, since 85% damage dealt means she needs more raw AP to hit the same numbers, and one defensive item, because of the 110% damage taken and the missing escape. These four do the job.

In practice, Luden’s Echo makes sense as the first buy. Its passive fires six Echoes that deal bonus magic damage to the target and nearby enemies, and the 600 Mana matters on a champion who throws Lucent Singularity every 8 to 10 seconds all game. Malignance is the second. Hatefog burns the ground under any champion Final Spark hits for 3 seconds, dealing magic damage per second and lowering their Magic Resist (a beam that hits all five is the whole point of picking her here).

Rabadon’s Deathcap is the big one. 130 Ability Power plus 30% of your total, the only item on this list that scales with everything else you bought. When does Zhonya’s Hourglass move up the order? Only when the enemy has two divers and you keep dying before Final Spark fires. Otherwise it can come last. Time Stop grants 2.5 seconds of Stasis, which buys time for your team to reach you.

How do you play her on the Howling Abyss?

• Lead with Lucent Singularity, not Light Binding. The slow lands on a group, the detonation damages everyone inside, and the 8 to 10 second cooldown means you can afford to miss.
• Auto attack after every spell. Illumination only pays out when your next attack lands.
• Bind the second target on purpose. Light Binding stops at two enemies, so line it up with the carry standing behind the tank.
• Throw Prismatic Barrier through the team. At 80% strength the shield is weaker, so cover three or four allies with one cast instead of one.
• Charge Final Spark from behind your tank. Lux gathers energy before the beam fires, and at 110% damage taken that’s a bad moment to have someone on you.

Real talk, none of that is mechanically hard. What gets Lux killed on the Abyss is walking forward for a kill she can’t reach, because she has no dash or blink and the diver standing in that clump is waiting for exactly that.

How do shopping and Mark change the game?

You can’t recall in ARAM. You shop at the fountain at the start and each time you respawn. The catch is, a Lux who dies at the wrong moment sits on unspent gold while the fight goes on without her, and that hurts a build with a 3500 gold Deathcap in it (that’s the priciest item on the list). Health relics in the lane are your other way to recover, since there’s no walking back to base to heal.

Mark is the mode’s summoner spell. You toss a snowball, and a landed hit opens up a dash onto whoever it struck. For Lux the dash is risky, since a mage with no escape who jumps into five enemies at 110% damage taken has no way back out, so take the follow-up only when the target is alone and low. Once the game loads, your summoner spells cannot be changed, and they remain the same until the match ends. Put simply, decide this in the lobby.

Is Lux good in ARAM?

Yes, with the nerfs priced in. Lux deals 85% damage, takes 110% damage and shields at 80%, and she’s still a reasonable pick because her damaging spells hit an area or two targets, and the Abyss is one lane with five players per team.

What beats her is a team that can get to her. Champions with a way to close the gap are the ones that trouble her most, since she has no dash or blink and has to land Light Binding or the Lucent Singularity slow to keep them off her. Riot lists her as both Mage and Support, and the support side matters on the Abyss, since on a bad day the slow and the shield still do work when the damage doesn’t (our guide to LoL roles explains how those two jobs differ). For the champions who trouble her on Summoner’s Rift, see the Lux counters guide. The Lux skins page collects her skins, and our LoL items database holds the stats and history for each item mentioned above.

A good Lux ARAM game comes down to Lucent Singularity on the clump, an auto attack after every spell, and firing Final Spark from behind someone bigger than you.
