Genshin Impact's Luna 4, also known as version 6.3, was officially previewed during a dedicated livestream. The event highlighted the patch's features, including the addition of playable characters Columbina, Zibai, and Illuga, and the return of Lantern Rite in Liyue as the year turns. The update is scheduled to go live on the evening of January 13.
The stream also revealed three redemption codes—ComeNightorDay, Zibai0515, and GallopYeah—that players can exchange for Primogems along with Mora and Adventurer’s EXP. The codes expire on January 4 at 11 a.m. EST, so players will want to redeem them promptly.
Redeeming is straightforward: log in and enter codes on the official redemption website, or open the in-game Settings menu and input them there. Copy-pasting the codes from the livestream post tends to minimize errors. After successful redemption, rewards land in the in-game mail shortly afterward.
Polygon’s recap notes additional livestream highlights, including further details on Nod-Krai's upcoming Archon Quests and confirmation that Luna 4 will launch on January 13. Lantern Rite's return continues to be a seasonal cornerstone for Liyue, inviting players to revisit the city for the new year.
