Overview
- HoYoverse aired the Luna IV Version 6.3 special program on January 2 via YouTube and Twitch, confirming the patch will go live on January 14.
- The livestream issued three codes—ComeNightorDay, Zibai0515, and GallopYeah—that together grant 300 Primogems, 5 Hero's Wit, 10 Mystic Enhancement Ore, and 50,000 Mora.
- Codes can be redeemed once per account either in-game through Settings > Account > Redeem Now or on the official Genshin Impact redemption website.
- Moonlit Duel Trials debuts as a limited-time, wave-based arena with co-op-enabled rounds, shared buff triggers, daily modifiers, and adaptive boss difficulty.
- Ephemeral Convergence introduces temporary resonance links that share a fraction of energy regeneration across linked characters to smooth burst rotations without replacing core ER builds.
