Cartethyia Guide – Mastering the Erosion Queen in Wuthering Waves 2.4

Cartethyia has finally arrived in Wuthering Waves 2.4, and she’s as flashy and ferocious as everyone hoped. With a dual-form mechanic, erosion-based damage scaling, and a cinematic playstyle, Cartethyia offers depth and destruction in equal measure. This guide covers everything you need to dominate with Cartethyia: her kit, mechanics, rotations, best builds, team comps, and more.

Cartethyia’s gameplay centers around switching between her base form and her enhanced form, Flirtilis. She generates swords, absorbs them for buffs, then unleashes chaos in her transformed state.

🔹 Core Mechanics

• HP Scaling: All of Cartethyia’s damage scales with her HP, giving her above-average tankiness.
• Sword Generation & Absorption:
• • Heavy/intro attack → Sword 1
• • Basic Attack (4th hit) → Sword 2
• • Resonance Skill → Sword 3
• • Plunge attack to absorb all three swords and gain buffs

🔸 Transformation: Flirtilis Form

• Triggered via Liberation after absorbing three swords.
• Gains a new moveset: fresh basics, heavy, aerials, and resonance skill.
• Goal: fill the Forte bar through attacks to unleash her Liberation again.
• Post-Liberation: Reverts to base Cartethyia.

⚠️ Flirtilis Drawback: Her HP is halved temporarily, but refunded on her Liberation.

Cartethyia thrives on erosion stacks, which are arrow-type DoT effects:

• Her passive grants 30–60% more damage against eroded targets.
• Flirtilis Liberation deals +20% damage per erosion stack removed (up to 5 stacks = +100%).

Applying Erosion:

• Basic 4 → 1 stack
• Resonance Skill → 2 stacks
• Plunge & various skills also apply erosion

For maximum burst, build up 5 stacks before triggering Flirtilis’ Liberation.

💥 Simple Combo:

1. Intro → Basic 4 → Resonance Skill → Auto Plunge
2. Liberation to enter Flirtilis
3. Resonance Skill 1 → Skill 2 → Spam Basic until Forte full
4. Liberation → Outro

🎯 Advanced Combo:

1. Same Cartethyia setup
2. Flirtilis Skill 1 → Midair Plunge (hold Basic)
3. Skill 2 → Basics 3–5 → Heavy 1–2
4. Liberation → Outro

This version is faster and more compact, ideal for tight fights or quick clears.

Pro tip: You can revert from Flirtilis back to Cartethyia before Forte fills to pause buffs and swap strategically.

Best Set:

• Windward Pilgrimage (5-piece):
• • 2-piece: +10% Arrow Damage
• • 5-piece: +10% Crit Rate & +30% Arrow DMG against eroded enemies

Recommended Echo:

• Reminiscence – Floorless: +20% Arrow Damage

Main Stats:

• 4411 setup (best):
• • 4-cost: Crit Rate / Crit DMG
• • 1-costs: All HP%
• 43311 setup is viable but ~4% weaker

Substat Priority:

• Crit Rate > Crit DMG > HP% > Normal & Liberation DMG
• Energy Regen: ~107–122% (depending on team)

1. Defier’s Thorn (Signature) – Massive HP%, erosion bonus, and defense ignore
2. Red Spring – Usable at 81% of signature
3. Emerald of Genesis – 78.5%
4. Guardian Sword (3★) – Viable (~73.8%) thanks to HP boost

Cartethyia is an incredibly satisfying and cinematic unit that rewards good rotation execution and team synergy. Her dual forms add depth, and her Flirtilis mode feels powerful and fluid — especially when paired with Chakona.

If you're into high-damage burst rotations, erosion stacking, and flashy transformations, Cartethyia is a strong pick. Just be ready to experiment with her combos and take advantage of her flexible playstyle.

Let the winds sweep your foes — and maybe your wallet too.
