Lune Build Guide – Mastering the Elemental Virtuoso

In the richly woven tapestry of Clair Obscur: Expedition 33, Lune emerges as a character of profound depth and versatility. As a scholar and mage, she brings a unique blend of intellect and elemental prowess to the Expedition. Her barefooted presence and serene demeanor contrast with the turbulent world around her, embodying a harmonious balance between knowledge and power.

While characters like Maelle draw inspiration from French fencing traditions, Lune’s design and mechanics are deeply rooted in the game’s innovative “Stains” system—a mechanic that sets her apart and defines her role within the party.

Understanding the Stains System

The “Stains” system is central to Lune’s gameplay, offering a dynamic approach to elemental magic. Here’s how it works:

Generation of Stains: Lune generates elemental “Stains” through specific skills, such as “Elemental Trick.” Each Stain corresponds to an element—Fire, Ice, Lightning, or Earth.
Consumption of Stains: Advanced skills require the consumption of specific combinations of Stains. For instance, the powerful “Elemental Genesis” skill demands one Stain of each element to unleash its full potential.
Strategic Management: Players must strategically manage the generation and consumption of Stains to maximize Lune’s effectiveness in combat. This involves planning skill sequences and anticipating enemy weaknesses.

Mastering the Stains system allows Lune to adapt to various combat scenarios, providing both offensive and supportive capabilities. Her ability to manipulate elemental forces makes her an invaluable asset, capable of exploiting enemy vulnerabilities and bolstering her allies.

By embracing the intricacies of the Stains system, players can unlock Lune’s full potential, transforming her into a formidable force within the Expedition. Her unique mechanics not only enrich the gameplay experience but also underscore the game’s commitment to innovative and engaging character design.

Certainly! Here’s an expanded Core Attributes: Agility & Defense section for Lune’s build guide, focusing on how each attribute shapes her role in Clair Obscur: Expedition 33, particularly when using the Stains system for elemental skill chaining and support control.

Core Attributes: Agility & Defense – Lune’s Foundation of Rhythm and Resilience

Lune is not a bruiser nor a frontline tank — she’s a rhythmic elemental tactician, and her stat priorities reflect that. Her strength doesn’t lie in raw power, but in the ability to act frequently, manage AP and elemental Stains, and stay on the field long enough to support or unleash devastating magic at the right moment.

Agility – The Flow of Combat

What It Does: Increases turn frequency, allows Lune to act earlier and more often in combat rounds.
Why It’s Important:
- Enables early setup of elemental Stains using skills like Elemental Trick, giving her team an elemental advantage from the first round.
- Allows Lune to reapply status effects (like Burn or Shock) before they expire, maintaining debuff uptime on enemies.
- A faster Lune means quicker AP regeneration via passives like Energizing Turn or Luminas like Cheater.

Build Tip: Opening a battle with full AP and acting first lets Lune execute powerful combos early (e.g., setting up Genesis or Hell), which can often decide the pace of the entire encounter.

Defense – Grace Under Pressure

What It Does: Increases Lune’s resistance to physical and magical attacks.
Why It’s Important:
- Unlike DPS characters, Lune needs to stay alive longer to build Stains and cast multi-stage skills.
- Most of Lune’s best weapons (like Choralim) scale with Defense, making this a hybrid stat that fuels both survivability and damage output.
- Helps counterbalance risky Pictos like Glass Cannon or Shortcut, giving her more breathing room when not hiding behind Gustave or Sciel.

Playstyle Note: If you’re planning to use Lune as a healer/support mage, Defense becomes essential to survive while casting spells like Tree of Life or Purification. Even in offensive builds, a decent Defense base makes her less fragile during long encounters.

Summary: Attribute Priority by Playstyle

Build Type	Primary Stat	Secondary Stat
Offensive Mage	Agility	Vitality/Luck
Support/Healer	Defense	Agility
Balanced Utility	Agility	Defense

Lune’s attribute strategy isn’t just about numbers — it’s about timing and survival. Agility gives her control, and Defense gives her endurance. When combined, they enable her to sustain the elemental rhythm that defines her gameplay: apply, amplify, react, and recover — all within the span of a few tactical turns.

Other Stats: Situational Use for Advanced Builds

Might – Low Priority

What It Does: Boosts base attack and offensive skill damage.
Why It’s Low for Lune:
- Lune’s damage isn’t from physical strength, but from elemental abilities that scale with other attributes or require elemental Stains.
- Most of her weapon and skill scaling does not benefit significantly from Might unless using very specific off-role weapons.

Use Only If: You’re intentionally building Lune as a pseudo-DPS using weapons with Might scaling (e.g., Trebuchim has some synergy), but it’s not recommended unless you’re experimenting.

Vitality – Optional in Hybrid Builds

What It Does: Increases HP pool and improves survival against all damage types.
When It Makes Sense:
- For newer players or in solo-friendly runs, boosting Vitality early can offset Lune’s natural squishiness.
- Some early-game weapons (like Trebuchim) scale with Vitality, and it can make a difference when facing enemies that pierce Defense.

Situational Benefit: If you want Lune to act as a backup off-healer or semi-tank in a team lacking Gustave or Sciel, Vitality can help buy her time to set up Stains or cast Tree of Life.

Luck – Build-Dependent

What It Does: Increases critical hit rate and enhances crit-scaling effects from weapons or Pictos.
Why It’s Niche:
- If you use weapons like Trebuchim or run crit-based Pictos (e.g., Charging Critical, Immaculate), Luck can meaningfully increase her skill activation frequency and Gradient Charge gain.
- However, Lune’s default toolkit isn’t built around crits — it’s built around status application and element cycling.

When to Use: Crit-heavy builds where you want Lune to generate AP or Charge faster through frequent crit triggers, especially when paired with high-hit-count skills.

Quick Stat Priority Reference by Build Type

Stat	Support/Healer	Elemental Caster	Crit-Cycler	Experimental DPS
Agility	★★★★★	★★★★★	★★★★☆	★★★☆☆
Defense	★★★★★	★★★★☆	★★★☆☆	★★★☆☆
Vitality	★★★☆☆	★★★☆☆	★★☆☆☆	★★★☆☆
Luck	★★☆☆☆	★★☆☆☆	★★★★☆	★★★☆☆
Might	★☆☆☆☆	★☆☆☆☆	★★☆☆☆	★★★★☆ (niche)

Final Insight

Lune is not built for brute force — she’s designed for finesse, timing, and scaling through elemental synergy.
If you’re allocating stats blindly or leaning too hard into raw damage, you’ll miss what makes her effective: control over the battlefield.
