As the Genshin Impact community counts down to the Luna III update launching tomorrow on December 3, 2025, bringing the highly anticipated Durin and Jahoda to the roster, eyes are already turning to the future. While players gear up for these new additions, whispers of the enigmatic Moon Maiden, Columbina, have fans buzzing. Early leaks suggest she'll debut in Luna IV alongside a mysterious new 4-star character and the White Horse Adeptus. But the real game-changer? A brand-new elemental reaction dubbed Lunar-Crystallize, leaked by reliable insider Seele.

Buckle up, Travelers. This could shake up team comps like never before.

Breaking Down the Lunar-Crystallize Reaction

Prominent leaker Seele recently dropped bombshell details on X about this innovative reaction, rumored for Luna IV. Unlike traditional elemental combos, Lunar-Crystallize is hyper-specific:

  • Trigger Requirements: Exclusive to Geo and Hydro elements. Pyro, Cryo, and Electro? No dice. They can't activate it.
  • Activation: Occurs when Geo comes into contact with Hydro under "select conditions" (exact details still murky, but likely involving field auras or blooms).

Upon triggering, three Lunar Wards spawn near the affected opponent. For every three Lunar-Crystallize reactions, a powerful Lunar Ward Resonance kicks in, unleashing Geo DMG to all nearby enemies. It's a rhythmic, build-up style payoff reminiscent of Overload or Superconduct, but with a lunar twist.

Scaling and Synergy: Crit-Focused Powerhouse

Leaks hint at deep integration with character stats:

  • Damage scales with the Crit stats (Crit Rate, Crit DMG) of the characters who apply the elements, rewarding high-risk, high-reward builds.
  • Overall reaction DMG draws from stats of ALL party members contributing elements; making it a true team effort. Expect hypercarry Geo/Hydro comps to dominate.

This positions Lunar-Crystallize as a premium reaction, likely tied to lunar-themed mechanics introduced in recent updates.

New Characters Poised to Exploit It

No new reaction drops without fresh blood to wield it. Leaks point to:

  • White Horse Adeptus: A shiny new Geo character, primed as the reaction's poster child. Her kit could revolve around Hydro application and Ward generation.
  • Mystery 4-Star Support: A dedicated Lunar-Crystallize enabler, dropping in the same Luna IV patch. Perfect for F2P players looking to chase the meta.

These arrivals align perfectly with Columbina's phase, potentially forming a lunar powerhouse banner. If true, Lunar-Crystallize could breathe new life into Geo (finally relevant beyond shields?) and Hydro (beyond Vaporize/Bloom spamming).

A Word of Caution

Note: All info here stems from early leaks by Seele and is subject to change. HoYoverse loves a good bait-and-switch. Take it with a grain of salt until official reveals. Still, with Luna III dropping tomorrow, the hype train is full steam ahead.
