The Most Overpowered Lune Dark Stain Build in Clair Obscur: Expedition 33
Clair Obscur: Expedition 33 has captivated RPG fans with its stunning visuals, deep narrative, and intricate turn-based combat. Among its diverse cast, Lune, the elemental mage, shines as a versatile powerhouse capable of dishing out massive damage or supporting her team with healing and buffs. Her unique Stain mechanic—generating and consuming elemental and Dark Stains to enhance skills—makes her one of the most tactical characters in the game. While Lune excels in Fire, Lightning, and healing builds, her Dark Stain build, centered around the Scaverim weapon and skills like Hell and Elemental Genesis, is widely regarded as her most overpowered setup. This build leverages Dark Stains to amplify skill damage by up to 300%, turning Lune into an endgame juggernaut capable of obliterating bosses like Renoir or Simon in a single turn. In this 1500-word guide, we’ll explore how to craft this devastating build, including the best weapon, skills, Pictos, Luminas, attributes, and team synergies, updated for the May 2025 meta.
Why Lune’s Dark Stain Build?
Lune’s combat revolves around generating Stains (Fire, Ice, Lightning, Earth, Light, and Dark) that enhance her skills’ damage, reduce AP costs, or add effects like Burn. Dark Stains, introduced later in Act 2, are unique because they universally boost any skill’s damage by 50% per stain, stacking up to 300% with four Dark Stains. Unlike elemental Stains, which require specific combinations (e.g., Ice Stains boosting Fire skills), Dark Stains are versatile, making them ideal for endgame fights where enemies have varied resistances. The Scaverim weapon, combined with skills like Hell and Elemental Genesis, maximizes Dark Stain generation and consumption, allowing Lune to deal millions of damage in a single turn. Despite a recent patch nerfing Elemental Genesis’s base damage by 15%, this build remains dominant due to its flexibility and raw power, as confirmed by community discussions on X. Here’s how to optimize Lune’s Dark Stain build to dominate Clair Obscur.
Core Components of the Build
To unleash Lune’s full potential, focus on five key areas: her weapon, skills, Pictos and Luminas, attributes, and team synergy. This build assumes you’re in Act 3 (Level 60) with access to endgame gear and skills, but we’ll also cover early-game transitions.
1. Weapon: Scaverim
Scaverim is Lune’s best-in-slot weapon for the Dark Stain build, obtainable by defeating the stranger in the Gestral Village Arena Tournament as Maelle in Act 3. Its upgrades make it the cornerstone of this build:
Level 4: 50% chance to generate a Dark Stain when consuming any Stain, accelerating Dark Stain accumulation.
Level 10: Consuming a Dark Stain with a Base Attack increases damage by 200%, offering a fallback for low-AP situations.
Level 20: With four Dark Stains active, any skill deals +300% damage and consumes all Stains, perfect for nuking with Hell or Elemental Genesis.
Scaverim scales primarily with Defense and Luck, boosting Lune’s survivability and critical hit chance. Its Dark Stain synergy eliminates the need for elemental-specific rotations, allowing Lune to focus on stacking Dark Stains for massive damage. If you’re still in Act 1 or 2, use Lighterim (found in Spring Meadows) to build Fire Stains and transition to Scaverim later.
2. Skills: Dark Stain Nukes and Burn Support
Lune’s skill loadout should prioritize Dark Stain generation, high-damage attacks, and Burn application to synergize with teammates like Maelle. Here’s the optimal setup:
Hell: A late-game Fire skill that deals massive AoE damage and applies 5-10 Burn stacks per enemy. With four Dark Stains, Hell’s damage skyrockets, making it ideal for clearing groups or chunking bosses.
Elemental Genesis: Lune’s ultimate attack, requiring one of each Stain (or Light Stains as wildcards). It delivers rapid multi-hit strikes, dealing extreme damage to all enemies. Post-patch, its base damage is slightly lower, but with four Dark Stains, it can still hit for millions.
Electrify: A low-cost Lightning skill that generates two Lightning Stains. Use it early to build Stains for Hell or Elemental Genesis. Its multi-hit nature also triggers critical hits with Critical Burn.
Wildfire: A mid-game Fire skill that applies Burn and generates Fire Stains. It’s great for setting up Burn synergy with Maelle’s Burning Canvas and building Stains for Hell.
Revitalization: A party-wide healing skill boosted by Fire Stains. It ensures Lune can support the team in prolonged fights, especially in Expert difficulty.
Thermal Transfer: A utility skill that consumes Earth Stains to apply Cold damage and gain extra AP. It’s essential for maintaining AP economy and setting up Hell or Elemental Genesis.
Rotation: Open with Electrify or Wildfire to generate Stains and apply Burn. Follow with Thermal Transfer to regain AP and consume Earth Stains (if available). Once you have four Dark Stains (via Scaverim’s Level 4 passive), cast Hell for AoE fights or Elemental Genesis for single-target bosses. Use Revitalization as needed to keep the party alive. This rotation maximizes Dark Stain uptime and damage output.
3. Pictos and Luminas: Amplifying Damage and AP
Pictos and Luminas enhance Lune’s damage, Stain generation, and survivability. Prioritize those that boost critical hits, AP, and Burn synergy:
Pictos:
Critical Burn: +25% critical hit chance against Burning enemies, synergizing with Wildfire and Hell.
Burn Affinity: +25% damage against Burning enemies, amplifying Hell and Elemental Genesis.
Energising Start IV: +4 AP at battle start, allowing immediate Electrify or Wildfire casts.
Dead Energy II: +3 AP on enemy kills, sustaining Lune’s AP for Hell or Elemental Genesis.
Burning Shots: 20% chance to apply Burn on Free Aim shots, enhancing synergy with Maelle.
Marking Shots: 20% chance to apply Mark on Free Aim shots, boosting damage for allies like Verso.
Luminas:
Cheater: Allows Lune to cast high-AP skills with slightly less AP, improving rotation flexibility.
Energising Heal: Grants AP when using Revitalization, keeping Lune’s AP pool healthy.
Dodger: +1 AP per perfect dodge (once per turn), rewarding skilled play.
Energy Master: Increases max AP, enabling more Hell casts in long fights.
Healing Fire: Heals Lune when attacking Burning enemies, boosting survivability.
Exposing Attack: Applies Defenseless on Base Attacks, increasing enemy damage taken.
Note: Avoid Roulette or Augmented Aim unless using Trebuchim in early-game, as Scaverim focuses on skill damage, not Free Aim.
4. Attributes: Balancing Damage and Speed
Lune’s attributes should prioritize Defense and Luck for Scaverim scaling, with Agility for turn frequency. Here’s the recommended spread for Level 60 (~180 points):
Defense (70-80 points): Boosts Scaverim’s damage and increases Lune’s survivability, crucial for Expert mode.
Luck (60-70 points): Enhances critical hit chance, synergizing with Critical Burn and Scaverim’s scaling.
Agility (30-40 points): Increases turn frequency, allowing faster Stain stacking and skill casts.
Might (10-20 points): Minor investment for elemental skill damage.
Vitality (10-20 points): Ensures Lune survives stray hits, especially in NG+.
Use Recoat items to respec if transitioning from a Fire or healing build. This spread optimizes Scaverim’s damage while keeping Lune fast and durable.
5. Team Synergy: Maximizing Lune’s Impact
Lune shines in a party with Maelle and Verso, who amplify her Burn and damage output. Here’s the optimal setup:
Maelle: Equip her Burning Canvas build (as detailed in prior conversations) with Medalum to apply Burn and deal massive single-target damage. Her Swift Stride and Pyrolyse synergize with Lune’s Wildfire and Critical Burn, boosting critical hits. Maelle acts second to capitalize on Lune’s Burns.
Verso: A support/DPS hybrid. Use Marking Shot and Defiant Strike to apply Marks, increasing damage for Lune’s Hell and Elemental Genesis. Equip Powerful and Rewarding Mark to grant Lune extra AP and damage buffs. Verso acts first to set up enemies.
Turn Order: Verso > Maelle > Lune. Verso Marks and buffs, Maelle applies Burn and breaks shields, and Lune finishes with Hell or Elemental Genesis for millions of damage.
Optional: Replace Verso with Sciel for her All Set skill, which grants Powerful, Shell, and Rush to Lune, boosting damage and speed. However, Verso’s Marking is generally more effective for this build.
Post-Patch Adjustments
The May 2025 patch reduced Elemental Genesis’s base damage by 15% and fixed a bug where Scaverim’s Level 20 passive stacked multiplicatively with Burn Affinity. Despite this, the Dark Stain build remains overpowered due to:
Unnerfed Dark Stains: The +300% damage boost from four Dark Stains is untouched, keeping Hell and Elemental Genesis lethal.
Burn Synergy: Maelle’s Burning Canvas and Lune’s Wildfire stack Burn quickly, amplifying Critical Burn and Burn Affinity.
AP Economy: Energising Start, Dead Energy, and Thermal Transfer ensure Lune can spam high-AP skills despite the nerf.
To adapt, focus on stacking Dark Stains faster with Scaverim’s Level 4 passive and lean on Hell for AoE fights, as its Burn application is more reliable post-patch.
Playstyle Tips
Stain Management: Always aim for four Dark Stains before casting Hell or Elemental Genesis. Use Electrify and Wildfire to build initial Stains, then rely on Scaverim’s 50% chance to generate Dark Stains.
AP Conservation: Avoid Base Attacks unless consuming a Dark Stain for Scaverim’s 200% boost. Use Thermal Transfer and Energising Heal to maintain AP.
Burn Synergy: Coordinate with Maelle to keep enemies Burning, maximizing Critical Burn and Burn Affinity.
Dodge Timing: Equip Dodger and practice perfect dodges to gain extra AP, especially in Expert mode.
Boss Fights: Against single-target bosses like Renoir, use Elemental Genesis with four Dark Stains for a one-shot. For groups, spam Hell to clear waves.
Why This Build Is Overpowered
Massive Damage Scaling: Four Dark Stains grant a +300% skill damage boost, pushing Hell and Elemental Genesis into the millions. Players on X report one-shotting NG+ bosses with this setup.
Versatility: Dark Stains work with any skill, bypassing elemental resistances.
Team Synergy: Maelle’s Burn and Verso’s Marks amplify Lune’s damage, creating a devastating party.
Sustainability: Revitalization and Healing Fire keep Lune and the party alive, while Energising Start and Dead Energy ensure endless skill casts.
Endgame Dominance: Even post-patch, this build clears Renoir’s Drafts and optional bosses like Simon with ease.
Challenges and Counters
AP Dependency: Hell and Elemental Genesis are AP-intensive. Mitigate with Energising Start and Thermal Transfer.
Dark Stain RNG: Scaverim’s 50% Dark Stain chance can be inconsistent. Use Electrify to build backup Stains.
Endgame Difficulty: Expert mode enemies hit harder, so prioritize Defense and Healing Fire.
Learning Curve: Mastering Stain rotations takes practice. Start with a Fire build in Act 1 before transitioning to Scaverim.
Community Buzz
