Genshin Impact 6.3 (Luna IV) Leaks Tease a Must-Pull Banner — Here’s Who Might Headline

We are smack in the middle of Version 6.2 (Luna III), but all eyes are already drifting to 6.3. If the latest leaks are on the money, Luna IV is a big swing for Nod Krai and the whole Lunar reaction push — and the character lineup is the tell. Usual caveat: leaks are leaks. Treat all of this like plans that could still change.

Release window and what HoYoverse is teeing up

Current chatter pegs Genshin Impact 6.3 (Luna IV) for January 14, 2026, keeping to the six-week cadence and running two banner phases through mid-February. HoYoverse also has a Luna IV livestream set for January 1, 2026. Between Lantern Rite timing and the climax of the Nod-Krai Archon storyline, expect a packed show.

The newcomers (and why they matter)

Three new characters are reportedly tied directly into Nod Krai and the new Lunar reaction system, with Geo and Hydro front and center.

Columbina (5-star Hydro Catalyst)

The long-awaited Harbinger finally steps onto the field — positioned as the Archon-adjacent figure for Nod Krai in this version arc. Leaks point to her being a Lunar-focused sub-DPS and reaction enabler who scales heavily with Max HP, which makes sense for a unit whose job is to prime and detonate the new mechanics rather than hog the spotlight with raw burst.

"Winter nights know no mercy. She left her curtained nest in frost and snow; no one is obliged to restore that which she has lost."

Lore fans will appreciate the flavor: titles like The Moon Maiden and Welkin Moon's Homecoming, plus the name Columbina Hyposelenia getting tossed around.

Zibai (5-star Geo Sword)

The White Horse Adeptus from Liyue is rumored to be built around the Lunar-Crystallize reaction specifically. The interesting bit: leaks suggest her kit is about repeatedly triggering that reaction instead of spiking big numbers once. Translation: a gameplay style that plays the long game with sustained procs rather than fireworks.

Illuga (4-star Geo Polearm)

Support piece, through and through. Illuga is said to buff Geo damage and boost Lunar-Crystallize interactions, setting him up as the glue that makes Zibai (and other Geo units) tick. The synergy here is not subtle, which tells you where HoYoverse wants players to experiment in 6.3.

Banners at a glance (subject to change)

• Phase 1 (early January): Columbina is the headliner. Neuvillette is rumored to rerun alongside her — a neat fit with Lantern Rite scheduling and whispers of Spiral Abyss buffs that could favor his kit.
• Phase 2 (late January into February): Zibai and Illuga take the stage. The rerun in this phase is tipped to be Ineffa, the Electro Polearm user.

Why Luna IV looks like a pivot

Between Columbina enabling Lunar reactions from Hydro and Zibai/Illuga shaping a new Geo-centric play pattern with Lunar-Crystallize, this patch reads like a deliberate push to make the Lunar system feel essential rather than optional. Wrap that inside the conclusion of the Nod-Krai Archon arc and you have both the narrative payoff and the gameplay incentive landing at once.

We will know how much of this sticks when HoYoverse goes live on January 1. Until then, keep expectations flexible and your primos ready. Who are you eyeing if these banners hit as leaked?
