Long Night’s Oath represents a specialized artifact collection specifically engineered for characters who demonstrate exceptional proficiency in executing plunge attack maneuvers within Genshin Impact. This set introduces a sophisticated damage amplification system that rewards players who master aerial combat mechanics and timing precision.
The Long Night’s Oath artifact collection focuses exclusively on enhancing plunge attack capabilities, making it exceptionally effective for primary damage dealers who specialize in aerial assault tactics and charged attack combinations. When fully optimized with maximum stacks active, this equipment amplifies the wearer’s plunge damage output by 100%, effectively doubling the destructive potential of each descending strike.
Mechanics Deep Dive: The Radiance Everlasting stacking mechanism operates on independent timers, allowing skilled players to maintain high damage bonuses through careful ability rotation sequencing. Each stack provides 15% additional plunge damage, with the potential to reach 75% bonus damage from stacks alone, combined with the 25% from the 2-piece effect for total 100% enhancement.
Domain Accessibility: The Derelict Masonry Dock Domain becomes available upon reaching the Atocpan region in Natlan, scheduled for release with the Genshin Impact 5.5 update. Players should prepare their exploration teams accordingly to access this location immediately upon update deployment.

While virtually every playable character possesses the basic capability to perform plunge attacks (refer to Genshin Impact character tier list for comprehensive rankings), only a select group features combat kits specifically designed around this mechanic. Below are the premier candidates who can optimally leverage the Long Night’s Oath artifact set’s unique capabilities:
Xiao – The Conqueror of Demons: As the game’s original plunge attack specialist, Xiao experiences a significant 5-10% damage improvement compared to his previous best-in-slot option, Vermillion Hereafter. His elemental burst, Bane of All Evil, transforms his attack pattern into continuous plunge sequences, perfectly synchronizing with the artifact’s stacking requirements.
Gaming – Festival Firework Master: This pyro character’s kit revolves around plunge attack combinations following his elemental skill activation. Gaming can rapidly accumulate Radiance Everlasting stacks through his skill-plunge rotation pattern.
Kazuha – Scarlet Leap Enable: While primarily supporting teams, Kazuha can effectively utilize this set in main DPS configurations, particularly when paired with Bennett’s inspiration field for pyro-infused plunge attacks.
Future Character Considerations: The artifact set’s design suggests upcoming Natlan characters will feature plunge-focused mechanics. Players should consider pre-farming this set for future roster additions.
Common Optimization Mistakes: Many players incorrectly assume the set only benefits plunge attacks, overlooking the crucial charged attack and elemental skill components that generate stacks. Proper rotation involves alternating between these attack types to maintain maximum Radiance Everlasting uptime.
Team Composition Synergy: Pair Long Night’s Oath users with characters who provide attack buffs, resistance shredding, and off-field elemental application to maximize damage potential during plunge sequences.
Acquiring the Long Night’s Oath artifact set requires strategic resource management and understanding of Genshin Impact’s progression systems. The primary acquisition method involves farming the Derelict Masonry Dock Domain located in Atocpan, Natlan.
Farming Efficiency Strategy: To maximize your resin investment, focus on running the domain at its highest difficulty level (Level 90) once your adventure rank permits. This ensures maximum 5-star artifact drop rates and optimal stat potential.
Resin Allocation Recommendations: Dedicate approximately 1,200-1,800 resin (6-9 days of natural regeneration) to secure a functional 4-piece set with appropriate main stats.
Artifact Strongbox Consideration: While not immediately available in the artifact strongbox upon release, historical patterns suggest it will be added in subsequent updates, providing an alternative acquisition method for veterans with excess artifact fodder.
Pre-Farming Preparation: Before the 5.5 update releases, stockpile fragile resin and condensed resin to immediately begin farming upon domain availability. This provides a significant head start in gear optimization.
Stat Priority Guide: When farming for plunge attack specialists, prioritize Crit Rate/Damage circlets, ATK% sands, and appropriate elemental damage goblets. Substats should emphasize critical stats, attack percentage, and elemental mastery for reaction-based teams.
Time Investment Estimates: Expect to spend approximately 8-12 hours of active domain farming across multiple sessions to obtain a competitively viable set with proper main stats and acceptable substats.
