Clair Obscur: Expedition 33 has redefined turn-based RPGs with its dazzling visuals, intricate combat mechanics, and a roster of characters that shine in battle. At the heart of many players’ strategies is Lune, the elemental mage whose Stain-based abilities make her a versatile force. Among the countless builds circulating in gaming communities, one stands out for its sheer devastation: the Lune Oneshot Build, capable of dealing over 50 million damage per turn while amplifying party damage by up to 200%. This guide dives into crafting this game-breaking setup, exploring Lune’s skills, weapons, passives, and team synergy to dominate even the toughest encounters.

 

Lune’s Elemental Prowess

Lune joins the expedition early as a scholar driven to unravel the Paintress’s mysteries. Her combat style revolves around Elemental Stains—Fire, Ice, Earth, Lightning, and Light—which she generates and consumes to enhance her skills. These Stains can boost damage, reduce Action Point (AP) costs, or trigger special effects, with opposing elements (e.g., Fire and Ice) creating powerful synergies. The Oneshot Build leverages Elemental Genesis, a late-game skill that consumes four unique Stains (or Light Stains) to unleash an apocalyptic elemental attack. By stacking critical chance, AP efficiency, and party buffs, this build achieves astronomical damage and doubles the party’s output, making it a favorite for speedrunners and Expert difficulty players.

Crafting the Oneshot Build

To achieve 50 million+ damage per turn and 2x party damage, you’ll need to optimize Lune’s weapon, skills, Pictos, Luminas, attributes, and team composition. Here’s a comprehensive breakdown.

1. Weapon: Scaverim for Maximum Burst

While Kralim is excellent for Stain generation, the Scaverim is the go-to weapon for this build’s endgame potential, obtainable in Act 3 or through challenging side quests like the Endless Tower. Its passives are tailored for massive damage:

Dark Stain Generation: Generates Dark Stains when consuming active Stains, amplifying skill damage by up to 300%.
S-Rank Vitality Scaling: Boosts Lune’s health and damage, ensuring she survives to deliver the nuke.
50% Damage Boost: Increases overall skill damage, pushing Elemental Genesis into the millions.

Upgrade Scaverim to Level 10 to maximize its Dark Stain generation and damage scaling. For mid-game players, Choralim is a viable alternative, offering Burn synergy and critical chance boosts upon crits, though it lacks Scaverim’s raw power.

2. Skills: The Path to 50 Million Damage

The build centers on Elemental Genesis, supported by skills that generate Stains, ensure critical hits, and sustain AP. Here’s the optimal skill set:

Elemental Genesis: Consumes four unique Stains (or Light Stains) for colossal AoE damage, hitting 50 million+ with buffs and criticals.
Elemental Trick: Generates four Stains if Lune lands critical hits on all attacks, critical for setting up Elemental Genesis in one turn.
Immolation: Applies three Burn stacks and a Fire Stain, enabling Burn-based synergies and Thermal Transfer AP gains.
Thermal Transfer: Deals Ice damage and grants 4 AP if the target is Burning, ensuring Lune can chain skills.
Electrify: A low-cost Lightning skill generating two Lightning Stains, perfect for early Stain stacking or exploiting weaknesses.
Revitalization: Heals the party and generates Light Stains, providing a fallback for survivability.

These skills create a loop of Stain generation, critical hits, and AP recovery, culminating in Elemental Genesis’s devastating blow.

3. Pictos and Luminas: Criticals and Party Buffs

Pictos and Luminas are passive effects that amplify Lune’s damage and party synergy. For this build, focus on critical chance, AP recovery, and damage multipliers:

Critical Burn: Boosts critical chance by 25% against Burning enemies, ensuring Elemental Trick generates four Stains.
Cheater: Grants two consecutive turns, allowing Lune to cast Elemental Trick and Elemental Genesis in one cycle.
Painted Power: Removes the 9,999 damage cap, enabling Elemental Genesis to hit millions.
Energising Start: Provides extra AP at combat start, speeding up Stain generation.
Dodger: Grants 1 AP per perfect dodge (once per turn), leveraging Lune’s Agility.
Fortune’s Fury: Doubles party damage for one turn, amplifying the entire team’s output.

Add SOS Shell for survivability, applying Shell when Lune’s health drops below 50%, giving her a buffer to execute the combo.

4. Attributes: Critical Chance and Speed

Lune’s attributes should prioritize critical hits and turn frequency:

Luck (Primary): Pushes critical chance to 100% with Critical Burn, ensuring Elemental Trick reliability.
Agility (Secondary): Increases turn frequency, letting Lune act before enemies or allies.
Vitality: Boosts health and synergizes with Scaverim’s scaling, keeping Lune alive.
Defense: A minor investment to reduce damage taken, especially on Expert difficulty.

Target 99 points in Luck and 75 in Agility by endgame, with 50-60 in Vitality. Use Critical Burn and gear to hit 100% critical chance, as Elemental Trick depends on it.

5. Team Synergy: Doubling Party Damage

The build’s 2x party damage comes from team buffs and synergies that amplify Lune’s nuke and allies’ attacks. Recommended party members include:

Sciel: Her Fortune’s Fury doubles party damage, while Intervention grants Lune extra turns. The Chation weapon enhances Burn effects in Twilight state, boosting Immolation synergy.
Maelle: Her Medalum weapon and Spark apply Burn, enabling Thermal Transfer and Critical Burn. Swift Stride enters Virtuose Stance for massive damage on Burning enemies.
Verso: His Simoso weapon applies Marks with Marking Shot, increasing damage on Marked targets. Defiant Strike adds Vulnerability, further boosting Elemental Genesis.

The strategy is: Sciel casts Fortune’s Fury to double damage, Maelle and Verso apply Burn and Marks, and Lune uses Elemental Trick into Elemental Genesis. This combo can one-shot bosses like the Lampmaster while allies deal millions in follow-up damage.

Combat Execution

Here’s how to pull off the Oneshot in a boss fight:

Turn 1 (Setup)

: Sciel uses

Fortune’s Fury

to double party damage. Maelle casts

Spark

to apply Burn, and Verso uses

Marking Shot

for Marks. Lune casts

Elemental Trick

, landing critical hits (100% critical chance required) to generate four Stains.

Turn 2 (Nuke)

: With

Cheater

, Lune takes a second turn, casting

Elemental Genesis

to deal 50 million+ damage. If enemies survive, use

Thermal Transfer

on a Burning target to regain AP and follow with

Electrify

or

Immolation

.

For mobs, replace Elemental Genesis with Wildfire or Hell to clear groups, preserving AP for bosses. The 2x party damage from Fortune’s Fury ensures allies like Maelle and Verso clean up any stragglers.

Early-Game Alternatives

In Acts 1-2, Scaverim and Elemental Genesis may be unavailable. Use Trebuchim (found in Spring Meadows), which generates random Stains on Free Aim shots. Focus on Immolation, Mayhem, and Thermal Transfer to stack Burn and deal AoE damage. Equip Energising Start and Critical Burn to mimic the endgame setup’s flow. Transition to Scaverim and Elemental Genesis in Act 3 or New Game+ for the full Oneshot experience.

Challenges and Solutions

Critical Chance Dependency: Elemental Trick requires 100% critical chance. Stack Luck, Critical Burn, and Critical Vulnerability to guarantee crits.
AP Management: High-AP skills like Elemental Genesis demand efficient AP recovery. Use Thermal Transfer and Dodger to maintain momentum.
Enemy Resistances: Some bosses resist elements. Keep Mayhem or Hell as backups for flexibility.
Expert Difficulty: Enemies hit harder and act faster. Boost Vitality and equip SOS Shell to survive setup turns.

Why This Build Is Game-Breaking

The Lune Oneshot Build is celebrated for its ability to deal 50 million+ damage per turn, as seen in community posts and guides. Elemental Genesis’s uncapped damage, combined with Painted Power and Fortune’s Fury, shatters the game’s damage ceiling. The 2x party damage from Sciel’s buffs makes allies like Maelle and Verso equally lethal, creating a team that can clear endgame content like the Endless Tower in record time. Its versatility—switching to AoE for mobs or healing for survival—ensures it excels in all scenarios, from Story to Expert difficulty.

Conclusion

Lune’s Oneshot Build transforms Clair Obscur: Expedition 33’s mage into a nuclear powerhouse, delivering 50 million+ damage per turn while doubling party output. With Scaverim, Elemental Genesis, and strategic team synergy, you’ll obliterate bosses and breeze through the Continent’s challenges. Whether you’re aiming for speedruns or tackling New Game+, this build makes Lune the expedition’s undisputed star. Experiment with your own tweaks and watch enemies crumble before her elemental might.
