The figures in this guide come from 378,251 ranked solo games played on EUW, patches 16.18 to 16.21, read through Riot’s official API up to 24 October 2026: the same sample as Gankademy’s champion pages. “≈” marks a figure the app also gives as indicative.

Lux is also played in mid lane: 18,625 games, 51.5% won. The most-played build there is Luden’s Echo → Stormsurge → Shadowflame (30% of games, ≈ 53.0%).

The build that wins most

A build, here, is the order of the first three finished items. Out of the 3,593 Lux games as a support where those three items are known, the three most-played paths:

As a support as in mid, Lux plays as a damage mage: Luden’s Echo then Stormsurge. As a support, Malignance as the third item wins clearly more often than Shadowflame, on few games; in mid, starting with Malignance or ending with Rabadon’s Deathcap also does better than the most-played build.

With build 1, the game most often starts with 2 × Health Potion + Stealth Ward, the boots are Sorcerer’s Shoes (97% of games) and the skills are maxed in the order E > Q > W (95%). Most frequent next items: Rabadon’s Deathcap, Zhonya’s Hourglass, Malignance.

Runes and summoner spells

The most-played rune pages of Lux as a support, by keystone and trees:

Arcane Comet is Lux’s keystone, as a support as in mid. With Domination as the secondary tree it is by far the most-played page; Dark Harvest wins less often.

The full page most played with build 1: Arcane Comet, Manaflow Band, Transcendence, Scorch, Cheap Shot, Ultimate Hunter. Summoner spells: Flash + Ignite in 43% of games.

Matchups: the easiest and the hardest

Lux’s win rate against each opponent in the same role, compared with the champion’s usual 49.5%: the gap in points. Only matchups of at least 200 games are kept.

As a support, Lux loses mostly to enchanters who heal and disengage — Janna, Nami —, to Ashe, who out-ranges her basic attacks, and to Blitzcrank, who punishes her the moment she steps out from behind her minions. Stay behind your minions against Blitzcrank; against the enchanters, poke their marksman rather than looking for the engage. Against Senna or Mel, your range and your binding win the lane.

In mid lane, the hardest: Ekko (≈ −4.9), LeBlanc (≈ −4.7), Xerath (≈ −4.4); the easiest: Orianna (≈ +8.8), Sylas (+7.7), Akali (≈ +3.7).

The most frequent mistakes

Two habits measured on the 9,255 games with a minute-by-minute timeline, then the champion’s own mistakes. These gaps go with losing without proving the cause, but the habit to build is clear.

• Dying before 15 minutes. 54% of games have three or more deaths before the 15th minute; they win only 42.4%, against 63.6% when Lux dies once or less (24% of games). Instead: Lux has no escape but her binding and Flash. Poke from the edge of your range, and step back as soon as their engage support comes out of the fog.
• Placing too few wards. Games where Lux places 8 wards or fewer before 15 minutes (27%) win 46.1%; those with 12 or more (31%), 51.8%. Instead: ward the river brush before every trade and before every objective, with a control ward in your bag — your binding is worth twice as much when you see them coming.
• Ignite by default. Flash + Ignite is taken in 43% of Lux’s support games and wins 48.1%; Flash + Heal wins 51.1%. Instead: Heal, which also saves your marksman.
• Throwing the binding first, from too close. Your binding is your only defence: wasting it on poke leaves you with no answer to their engage. Instead: poke with your light zone, and keep the binding for the enemy who engages or for a sure target.
• Casting the ultimate at a free target. Your ultimate reaches very far, but leaves after a short delay: cast at a target free to move, it misses. Instead: cast it at a target already held by your binding or an ally’s control, or to finish a target running in a straight line.

With Gankademy

These are the figures of Gankademy’s Lux page. In champion select, the draft gives each option’s record against your lane opponent; once you lock, one click imports a suggested rune page into the client. In game, the reminder shows your build and your CS per minute; after it, the film narrated by your coach pauses on each decision. The draft · The coaches · What it reads.
