Lux
View on Wiki
Excellent (8.5/10)
Rare Relics OK
Lux is widely regarded as a top-tier Demacian champion with a highly satisfying spell-slinging playstyle. While her early game can feel slow without mana-generating relics or her C5 upgrade, her ability to generate infinite rallies and lasers once she reaches 6 mana makes her incredibly powerful.
Ultimate Spellslinger
Provides an essential starting mana gem and draws a card, accelerating Lux's game plan significantly.
The core engine of Lux's late-game. Once at 6 mana, doubling all spells leads to massive laser and rally generation.
Refills spell mana upon leveling up, enabling explosive turns where Lux can cast multiple high-cost spells immediately.
Strategy
This build focuses on ramping mana as quickly as possible. The Baton provides the starting mana needed to survive the early game, while Hidden Tome ensures you have the spell mana required to cast your big spells. Once you reach 6 mana gems, Chemtech Duplicator takes over, allowing you to double every spell, instantly leveling Lux and filling your hand with Final Sparks and Golden Aegis.
Titanic Ramp
Grants +1 starting mana if the champion is Titanic, which is crucial for Lux's slow early game.
Provides the necessary health to push Lux's stats to the Titanic threshold required by Starforged Gauntlets.- Doubles spells at 6 mana, serving as the primary win condition.
Strategy
If you do not have Lux's Incandescent Baton, this is the premier alternative for mana acceleration. Luminous Orb ensures Lux is Titanic, activating Starforged Gauntlets for the extra starting mana. The goal remains the same: survive until turn 4 or 5, reach 6 mana, and let Chemtech Duplicator overwhelm the opponent.
Rare Spellslinger
- The most important relic for Lux, doubling her spell output and rapidly generating her champion spells.
Provides a reliable 6-cost spell every round that removes threats and perfectly triggers Lux's laser generation.
Refills spell mana upon summoning Lux, allowing you to immediately cast a spell to protect her or advance her level-up.
Strategy
A highly effective build using only rare and common relics. Lost Chapter gives you the immediate spell mana needed to cast a spell the turn Lux is played. Arcane Comet guarantees you always have a 6-cost spell to cast, which is perfectly doubled by Chemtech Duplicator to obliterate enemy boards and generate multiple Final Sparks.
Passive Commander
Keeps Lux safe while she counts down, eventually summoning her for free.
Provides passive rerolls and higher chances for epic powers without needing Lux on the board.
Grants passive stats and Overwhelm to your board.
Strategy
Designed for encounters where playing a 5-cost Lux is too dangerous or slow. This build keeps her off the board or safely entombed while providing passive benefits to the rest of your deck. You win by casting spells and utilizing your supporting units rather than relying on Lux's physical presence in combat.
Other Relic Options
When combined with her C4 spell burn, this allows you to cast a spell, damage the Nexus, and drop Lux on Turn 1.
Her signature relic. It is very fun for summoning Garen and Galio, though it can sometimes cause board space issues and is considered less optimal than pure mana ramp.
An excellent alternative to Arcane Comet, providing a constant stream of spells to trigger her abilities.
Players disagree about Archangel's Staff on Lux. Some consider it essential for continuous spell mana generation, while others view it as a trap because Lux natively refills her own spell mana.
Constellation
Lux's constellation upgrades transform her from a solid champion into an unstoppable spell-casting powerhouse. Her upgrades primarily focus on mana generation and spell efficiency, which are critical for her high-cost playstyle.
Lighting the Way
Each round, the first time you spend mana to play a spell, refill spell mana up to its cost.
Pushing my Limits
+1 Starting Mana. When you play 6+ mana of spells, create a 0 cost Golden Aegis in hand.
Lighting the Way II
Each round, the first time you spend mana to play a spell, refill mana equal to its cost.Review
A massive quality-of-life improvement. It smartly refunds mana only when mana is actually spent, preventing 0-cost spells from wasting the effect.
Spell Burn
When you play a spell, deal 1 to the enemy Nexus.Review
Provides 'Spell Burn' (dealing 1 damage to the Nexus on spell cast). While the damage seems small, it easily enables Plunder relics like Packed Powder and chips away at the enemy Nexus during long spell chains.
Manaflow
Game Start: Get a mana gem.Review
Considered her most vital upgrade. The +1 starting mana gem is crucial for accelerating her game plan and ensuring she doesn't fall behind against aggressive encounters.
Eternal Radiance
When allies attack, create a Final Spark in hand. Your damaging spells and Skills deal 1 extra damage for each 6 mana you've spent on spells this game.Review
Upgrades Final Spark to Burst speed and scales its damage. This is a game-changing tempo boost that allows for reactive combat tricks and prevents the AI from responding to her lethal lasers.
Gameplay Tips
- Mulligan for Mana
Always hard mulligan for "Succession" (the 3-cost spell that summons a Dauntless Vanguard and grants an empty mana gem). It is the most important card in her starting deck for early acceleration.
- Avoid Spell Cost Reduction
Do not draft powers like "Glorious Evolution" or items that reduce the cost of your spells. Lux requires spending 6+ mana on spells to generate Final Sparks and Golden Aegis; making spells cheaper actively sabotages her win condition.
- Manage Hand Space
Lux generates a massive number of cards (Final Sparks, Golden Aegis, etc.). Be careful not to over-rally or cast too many spells without playing the generated cards, or you will obliterate your own win conditions due to a full hand.
- The Lissandra Matchup
Lux struggles significantly against the Lissandra adventure due to the "mana tax" on spells. Avoid using Chemtech Duplicator in this specific encounter, as doubling spells will rapidly increase their cost to unplayable levels.
- Burst Speed Lasers
Once you unlock her C6, Final Sparks become Burst speed. This allows you to use them as combat tricks to remove blockers after declaring an attack, pushing your units' damage directly to the Nexus.
