New Elemental Reaction: Lunar Crystallization in Genshin Impact 6.3

Recently, Genshin Impact has officially unveiled the Lunar Crystallization system, confirming its debut in the upcoming Nod-Krai expansion. Lunar Crystallization, a transformative enhancement to the Geo element's interaction with Hydro. Lunar Crystallization is a verified, game-changing mechanic set to redefine team-building and elevate Geo's role in the elemental reaction meta. This guide provides the definitive breakdown based on officially released information.

What is Lunar Crystallization?

Lunar Crystallization is an advanced, state-altering elemental reaction derived from the standard Crystallize reaction (Geo + Hydro). It is activated under the influence of specific characters from the Nod-Krai region.

• Core Transformation: When a Hydro and Geo element interact while a qualifying Nod-Krai Lunar-Reaction enabler (e.g., the confirmed 5-star character Columbina) is in the party, the reaction transforms into Lunar Crystallization instead of producing a standard crystal shard.
• Visual & Combat Effect: The reaction generates three "Lunar Wards" that orbit the target or appear in the vicinity.
• Resonance Payoff: Upon triggering three instances of Lunar Crystallization, the accumulated Wards trigger a powerful Lunar Ward Resonance, unleashing a significant burst of Area-of-Effect (AoE) Geo Damage.

The Lunar Crystallization reaction introduces three key revolutionary traits: first, its resonance damage can CRIT—unprecedented for any reaction derived from Crystallize; second, the damage scales based on the combined stats of all party members involved in triggering the reaction, incentivizing synergistic team investment; and third, it fundamentally transforms Crystallize from a purely defensive, shield-focused mechanism into a potent source of offensive Geo damage.

How to Trigger Lunar Crystallization?

Triggering this new reaction requires meeting specific conditions, as outlined in the official preview and character kits.

Mandatory character: A character with the "Lunar Blessing" passive talent must be in your active party. The primary and confirmed enabler for Lunar Crystallization is the 5-star Hydro Catalyst user, Columbina. Her kit allows her to convert standard Hydro-based reactions (like Crystallize) into their Lunar versions.

Elemental Application: You must apply both Hydro and Geo elements to an enemy. This is typically achieved by pairing Columbina (or another Hydro applicator) with a Geo character.

The Conversion: Once the standard Geo+Hydro Crystallize reaction is triggered, Columbina's Lunar Blessing passively converts it into Lunar Crystallization, initiating the Ward generation sequence. The character triggering the elemental application can be any party member.

 

Lunar Crystallization vs. Other Lunar Reactions

Lunar Crystallization is part of a broader new system of "Lunar Reactions" designed to enhance specific transformative reactions. Here is the officially confirmed distinction between the initially released Lunar Reactions:

Reaction	Base Reaction	Official Lunar Effect	Confirmed Primary Enabler
Lunar Crystallization	Crystallize (Geo + Hydro)	Generates Lunar Wards; Resonance deals CRIT-able AoE Geo DMG.	Columbina (5★ Hydro)
Lunar-Charged	Electro-Charged (Electro + Hydro)	Creates a persistent "Thundercloud" field that periodically strikes enemies with CRIT-able Electro DMG.	Ineffa (5★ Electro)
Lunar-Bloom	Bloom (Dendro + Hydro)	Enhauses Bloom into "Prismatic Blooms" that deal CRIT-able Dendro DMG upon creation and have altered homing behavior.	Lauma(5★ Dendro)

 

Lunar Crystallization Best Teams

Building a team to maximize Lunar Crystallization focuses on frequent reaction triggers and leveraging its unique scaling.

Core Enabler: Columbina (Hydro) is non-negotiable. She enables the reaction and is likely a significant source of Hydro application and personal damage.

Geo Trigger/Support:

• Zhongli: Remains a top-tier choice for his powerful shield, universal resistance shred, and persistent Geo pulses from his stele.
• Albedo: Provides excellent off-field Geo DMG and application via his Solar Isotoma, perfect for triggering frequent Crystallize.

New Geo Characters: Zibai or other new Geo characters may offer optimized synergy with the Lunar system.

Team I

Zibai + Columbina + Xingqiu/Yelan + Zhongli/Albedo

Zibai	Columbina	Yelan	Albedo
Zibai	Columbina	Xingqiu	Zhongli

Columbina, as the enabler, may face Energy Recharge challenges. Adding Xingqiu or Yelan creates "Hydro Resonance" for increased Max HP, while their off-field skills efficiently generate Hydro particles, greatly optimizing Columbina's rotation.

Xingqiu provides damage reduction, interruption resistance, and minor healing. Yelan provides on-field damage buffs and significant off-field damage. They contribute substantial personal damage while supporting Columbina.

This team performs flexibly and outputs smoothly in environments requiring Hydro shield breaks or where survival pressure is lower.

Team II

Zibai + Columbina + Illuga/Sandrone + Xilonen (C2)

Zibai	Columbina	Sandrone	Xilonen
Zibai	Columbina	Illuga	Xilonen

C2 Xilonen provides the invaluable universal Elemental RES Shred, the most scarce damage multiplier for Geo teams, fundamentally compensating for Geo's inability to trigger Amplifying Reactions. And her damage buffs and healing scale with Defense, which perfectly aligns with Zibai's Main DPS scaling and the Lunar Crystallization Full Radiance requirement, with zero wasted stats.

The future new 5-star Geo character Sandrone, as an off-field Sub-DPS, can provide extremely high off-field Geo damage and Geo application, pushing Lunar Crystallization trigger frequency and Resonance damage to its peak.

This lineup combines RES Shred, healing, high-frequency reactions, massive direct damage, and reaction damage into one, representing the theoretical ultimate form capable of handling any endgame challenge.

Future Outlook: This team represents the complete vision of the "Lunar Crystallization" system, where all characters (Sandrone, C2 Xilonen) are designed around it, eliminating historical mechanic conflicts.

Team III

Zibai +Columbina + Zhongli + Albedo/Geo Traveler

Zibai	Columbina	Zhongli	Albedo

Zhongli provides the game's strongest shield, granting the team "super armor" and universal Elemental RES Shred, allowing Zibai to focus on dealing damage without environmental pressure.

This team effectively utilizes high-investment characters many veteran players already own (Zhongli, Albedo), resulting in a low transition cost.

Albedo's "Solar Isotoma" or the Geo Traveler's constructs/burst provide stable, persistent off-field Geo application, continuously reacting with Columbina's Hydro to ensure Lunar Crystallization trigger frequency.

Note: This team cannot easily meet the "Full Radiance" Defense requirement. Zhongli's HP scaling does not contribute to reaction damage. It sacrifices some damage ceiling for unparalleled comfort.

Team IV F2P Delight

Zibai + Columbina + Illuga + Gorou

Zibai	Columbina	Illuga	Gorou

Core members are 0-constellation 5-star Zibai and Columbina. The key support, Illuga, is a 4-star Geo specialist support, making her easy to obtain. Gorou, a veteran 4-star Geo support, is already at high constellations for many players.

Gorou provides Defense, Geo DMG Bonus, and interruption resistance. Illuga is expected to provide Lunar Crystallization damage boost or additional Defense bonuses. Both perfectly match Zibai's Defense-scaling Main DPS nature and the "Full Radiance" requirement, solving the attribute mismatch issue with older Geo supports (like Zhongli).

Smooth Rotation: Geo Resonance provides Energy Recharge and Shield Strength. As dedicated supports, Gorou and Illuga effectively alleviate the Geo team's Energy requirements, ensuring smooth skill rotations for Zibai and Columbina.

 

Conclusion

For the Lunar Crystallization reaction, this mechanism successfully addresses years of player feedback regarding the limited reactivity of the Geo element by infusing its iconic defensive reaction with powerful and scalable damage. This is not a minor adjustment but a fundamental transformation that will give rise to entirely new team compositions and breathe fresh vitality into existing Geo characters.

Travelers should prepare for the arrival of the reaction by considering how to integrate their current Geo roster into teams built around Columbina. The era of Geo as a purely defensive element has come to an end; welcome to the age of crystalline offense. Most importantly, don’t forget to enjoy exclusive offers at LDshop~~!
