Complete guide to Genshin Impact Luna II Phase I events with optimization strategies and rewards breakdown
Luna II Phase I Overview and Key Dates
HoYoverse has unveiled the comprehensive event calendar for Phase I of Genshin Impact’s Luna II update, featuring an exciting lineup of limited-time activities and permanent additions. The initial phase introduces multiple engaging events including the adventure-focused Saurian Sojourn, challenging boss encounters in Stygian Onslaught, and refreshed character/weapon banners that will reshape team-building strategies.
These events will remain accessible from the Luna II version launch through the conclusion of the Song of the Welkin Moon version period. Strategic planning is essential as several events have overlapping timeframes, requiring players to prioritize based on their resource needs and playstyle preferences.
Miliastra Wonderland emerges as a groundbreaking UGC (User-Generated Content) game mode debuting in Luna II. This innovative feature enables collaborative gameplay with other Travelers while offering creative tools to design custom stages and challenges for the community. The mode represents HoYoverse’s continued commitment to player engagement beyond pre-designed content.
Following the reward structure established in Luna I, completing Archon Quest Song of the Welkin Moon: Acts III and IV before December 2, 2025 yields 560 Primogems, Character Ascension Materials, and additional valuable resources. This extended deadline provides flexibility for players progressing through the main storyline.
Saurian Sojourn Event Details
The Saurian Sojourn limited-time adventure event commences on October 24, 2025 and concludes on November 3, 2025, offering a compact 11-day window for participation. Successful completion unlocks substantial rewards including Primogems, Mora, Weapon Ascension Materials, and various enhancement resources crucial for character progression.
Pro Tip: Prioritize daily event completion rather than leaving it until the final days, as unexpected time constraints could cause you to miss valuable rewards. The event typically features progressive difficulty, so early completion of easier stages ensures baseline rewards even if challenging content remains unfinished.

Common Mistake to Avoid: Many players underestimate the time investment required for event mechanics and end up rushing through content, potentially missing hidden objectives or bonus rewards. Allocate at least 30-45 minutes per session for thorough exploration and completion.
Stygian Onslaught and Disturbance Outbreak
The Stygian Onslaught challenge receives a significant refresh on October 29, 2025, introducing new boss mechanics and reward structures. Simultaneously, the Disturbance Outbreak activates from October 29, 2025, through November 8, 2025, creating a 11-day period for intensive artifact farming using Original Resin.
During this Outbreak phase, defeating boss encounters becomes substantially more rewarding, providing enhanced artifact acquisition rates and quality. Completing various Stygian Onslaught challenges yields Primogems, Mora, Hero’s Wit, and the valuable Dust of Enlightenment for character development.

Advanced Strategy: Coordinate your resin usage with the Outbreak period for maximum efficiency. Pre-farm artifact enhancement materials beforehand so you can immediately upgrade any premium artifacts obtained. Consider using Condensed Resin to double reward acquisition while halving time investment.
Team Composition Advice: Prepare versatile team setups capable of handling multiple elemental shields and combat mechanics. Characters with shield-breaking capabilities and sustained damage output typically perform best in these challenging boss encounters.
Imaginarium Theater New Season
A fresh Imaginarium Theater season launches on November 1, 2025 and remains available until November 30, 2025, providing a full month to tackle its progressively challenging stages. Completion rewards include Primogems, Mora, Talent level-up materials, Sanctifying Essence, and Sanctifying Elixir for artifact enhancement.
The seasonal refresh introduces new Thespian Tricks specifically designed for Kinich, Rosaria, Hu Tao, and Beidou, available for exchange from Wolfy following the season commencement. These specialized enhancements can significantly alter character performance and open new strategic possibilities.

Optimization Tip: Focus on acquiring Thespian Tricks for characters you actively use in your primary teams first. The resource investment for obtaining all available tricks can be substantial, so prioritize based on your current roster and playstyle.
Progression Strategy: Complete lower difficulty stages early to accumulate resources for trick acquisition, then utilize those enhancements to tackle higher difficulty content for improved rewards. This snowball effect maximizes your overall efficiency throughout the season.
Sumeru Flagship Event and Free Character
The marquee Sumeru region flagship event debuts during Phase I, running from November 7, 2025 to November 24, 2025. This extensive 18-day event offers the most substantial rewards of Phase I, including a free 4-star Dendro archer Collei, Primogems, Hero’s Wit, Talent level-up materials, Mora, and the precious Crown of Insight for talent maximization.

Character Value Analysis: Collei provides excellent Dendro application for reaction-based teams, particularly valuable for Free-to-Play players building their roster. Even veterans can benefit from her constellation upgrades if she’s not already at C6.
Completion Strategy: Unlike shorter events, the flagship event typically features multiple acts released progressively. Plan to complete each act within 2-3 days of release to avoid last-minute rushing while ensuring you don’t miss any time-gated content or bonus objectives.
Advanced Optimization Strategies
Resource Management Priority: Focus your initial efforts on time-sensitive limited events before tackling permanent content. The Saurian Sojourn’s short duration makes it the top priority, followed by the Disturbance Outbreak for efficient artifact farming.
Resin Allocation Guide: During overlapping event periods, calculate your daily resin requirements and allocate accordingly. Stygian Onslaught and Disturbance Outbreak should receive priority when active, as their enhanced rewards represent limited-time opportunities.
Time-Saving Technique: Utilize the interactive map and community guides to pre-plan event completion routes. Many events feature hidden objectives or efficiency optimizations that aren’t immediately apparent, and preliminary research can save significant time during actual gameplay.
Common Pitfall Avoidance: Never let your resin cap at 160 during event periods, as this represents lost progression opportunity. Set reminders to check in periodically, especially during limited-time enhancement events like the Disturbance Outbreak.
