Understanding the Stains System

In Clair Obscur: Expedition 33, Lune’s identity as a hybrid damage-dealer and support mage is shaped by the unique Stains system. Mastery of this mechanic is essential to unlocking the best Lune build.

Clair Obscur: Expedition 33 Stains System of Lune

What Are Stains?
Stains are elemental charges—Fire, Ice, Lightning, Earth—generated by using specific skills. These charges are consumed by advanced abilities to amplify effects or unlock powerful moves.

Generation of Stains: Lune accumulates Stains through actions like Elemental Trick or free-aimed elemental shots.
Consumption of Stains: High-impact skills such as Elemental Genesis or Crippling Tsunami require specific Stain combinations to activate their full potential.
Tactical Use: You must rotate between generating and spending Stains effectively to maintain pressure and utility. Lune’s gameplay rewards players who can manage these layers strategically.

Why This Matters for Your Build
The best Lune builds revolve around managing AP and Stains efficiently. Whether you’re leaning into Flame and Ice to inflict Burn and Mark, or chaining Stains into massive AoE support abilities, Lune thrives on rhythm and smart planning.

Lune’s unique mechanics allow her to:

Apply multiple debuffs like Burn, Mark, or Freeze early in fights.
Support teammates like Maelle or Sciel by softening targets or setting up big plays.
Adapt her role fluidly between damage and control depending on the encounter.

Understanding this system not only enhances her personal output, but also dramatically improves overall team synergy, especially when paired with high-burst allies like Maelle. This guide will continue with optimized attributes, weapons like Choralim, and ideal Pictos to help you get the most out of your Lune build in Clair Obscur: Expedition 33.

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

Lune excels at controlling combat tempo and managing elemental Stains. Her core attributes should reflect her hybrid role as a support mage with burst potential.

Agility – The Flow of Combat
Boosts turn frequency, letting Lune act early and often. This allows for quick setup of elemental Stains, maintaining debuffs like Burn or Shock, and activating high-impact skills like Hell or Genesis before enemies respond. Early AP generation from Luminas like Energizing Turn becomes more effective with higher Agility.

Defense – Grace Under Pressure
Raises resistance and enables Lune to survive long enough to build and unleash multi-stage elemental combos. Key weapons like Choralim scale with Defense, offering a rare synergy of survivability and damage. Essential if Lune is used as a support or off-healer casting Tree of Life or Purification during prolonged battles.

Summary: Attribute Priority by Role

Offensive Mage: Agility > Vitality/Luck
Support/Healer: Defense > Agility
Balanced Build: Agility ≈ Defense

Other Attributes: When They Matter

Might: Generally low value, as Lune’s damage comes from elemental abilities. Only useful with off-meta weapons like Trebuchim.
Vitality: Optional in early game or solo play. Helps mitigate Lune’s fragility if no tank is present.
Luck: Situationally useful in crit builds with Charging Critical or high-hit-count skills. Not essential in standard builds focused on status effects and elemental cycling.

Lune’s gameplay thrives on tactical flexibility. With the right stat distribution, she maintains pressure, controls elemental flow, and sustains her team — all while adapting to the rhythm of battle.

Quick Stain generation + utility.

Electrify
Single-target Lightning attack with 3 hits. Critical hits add extra damage. Consuming a Fire Stain creates a Light Stain.
Works well for focused Stain building.

High-Damage Stain Consumption Skills

Hell
- Powerful AoE Fire attack (2 hits) that applies 5 Burn per hit. Deals self-damage if failed. Consumes Ice, Earth, and Lightning Stains for amplified power.
- Best used after setting up enemies with Burn from Wildfire.
Lightning Dance
- Single-target Lightning skill with 6 hits. Critical hits add bonus damage. Consumes Earth, Ice, and Fire Stains for maximum effect.

Support-Oriented Utilities

Thermal Transfer
Low Ice damage. If the enemy is Burning, Lune gains 4 AP. With 2 Earth Stains, she gets a second turn.
Best AP regeneration tool in her kit.
Healing Light
Restores HP and clears debuffs from an ally. Consuming 2 Earth Stains makes it free.
Reliable support with minimal cost.
Rebirth
Revives an ally and grants AP. Requires 3 Lightning Stains to remove the AP cost.
Must-have for late-game sustain.

Skill Rotation & Build Strategy

Openers: Start fights with Elemental Trick or Earth Rising to begin building your Stains pool.
Mid-fight Utility: If allies are low or enemies are applying pressure, switch to Healing Light or Thermal Transfer for tempo recovery.
Burst Phase: Use Hell or Lightning Dance when Stains align and the boss is vulnerable. Follow up with Genesis if all 4 Stains are available.
Burn-Based Loop: Apply Burn with Wildfire → Trigger Thermal Transfer for AP gain → Chain into high-cost skills.

By chaining skills around Stain economy and enemy status, Lune can dominate both in crowd control and targeted damage. Her versatility makes her an essential asset in any Expedition 33 team composition.

Team Synergy – Best Lune Team Compositions in Expedition 33

Lune’s strength lies in her flexibility. She supports the team with elemental debuffs, AP utility, and healing while dishing out respectable damage through her Stain system. This makes her fit into nearly any Expedition 33 party comp.

Lune + Maelle – Burn Setup into Burst Finish
Lune’s skills like Hell and Wildfire apply multiple Burn stacks, enabling Maelle to deal amplified damage using Percee or Sword Ballet. When built with Choralim, Lune also generates Gradient Charge fast enough to support Maelle’s early burst-heavy rotations.

Lune + Sciel – AP Sustain and Status Loop
Sciel’s Foretell system helps regenerate AP, which pairs well with Lune’s Thermal Transfer and Elemental Trick combos. Together, they can keep up constant status pressure (e.g., Burn, Slow) while enabling back-to-back high-cost skill chains like Lightning Dance or Sealed Fate.

Lune + Verso – Crowd Control and Debuff Exploitation
Lune applies Slow, Shock, and Burn across multiple enemies, allowing Verso to gain increased benefits from his shield-breaking and AOE-oriented skills. This team excels in Act II+ group encounters where debuff uptime directly boosts survivability and momentum.

Lune + Monoco – Gradient Synergy and Tactical Safety
Monoco’s mixed-role versatility makes him an ideal partner. Lune keeps him alive with Healing Light or Rebirth, while Monoco manipulates the field with taunts or hybrid attacks. Their synergy becomes powerful in longer fights where maintaining team stability is key.

Team Synergy Tips:

Parry-Centric Play: Use Empowering Parry and Energizing Parry to convert good parry timing into AP gain or bonus damage.

Conclusion – Why Lune Belongs in Every Expedition 33 Team

Lune is a cornerstone of flexible team building. Whether built for status effect chains, gradient burst healing, or stain-driven elemental nukes, her versatility allows her to shape shift into whatever the fight demands.

From melting enemies with Hell, to restoring full party stability with Tree of Life, Lune rewards players who plan ahead and execute rotations carefully.
