The Genshin Impact community has been buzzing with excitement since the introduction of Rerir, one of the most challenging boss fights in the game's history. As we move deeper into 2025, this formidable opponent continues to challenge even veteran players with his unique mechanics and devastating attacks.
Who is Rerir in Genshin Impact?
Rerir, also known as the Rächer of Solnari, stands as one of the Five Sinners of Khaenri'ah and leads The Wild Hunt. His lore is deeply intertwined with the game's overarching narrative about Khaenri'ah's destruction. Originally a secret agent of the Eclipse Dynasty, Rerir's primary mission was to exterminate the remaining descendants of the Crimson Moon Dynasty.
What makes Rerir particularly interesting is his complex backstory involving his girlfriend Tholindis and his friendship with Dainsleif. After absorbing a portion of Abyssal power, Rerir became unnaturally fixated with the moons beyond the False Sky, which plays directly into his boss mechanics.
Rerir Boss Fight Overview
The Rerir boss fight was introduced in Version 4.7 and has since received several updates to keep it challenging. Located in Nod-Krai, this encounter requires players to be at least Adventure Rank 45 with completed prerequisite quests.
Battle Phases
The Rerir boss fight in Genshin Impact consists of three distinct phases:
-
Phantom Form Phase: Rerir begins the fight in his phantom form, where he's highly mobile and uses illusory attacks. His signature move during this phase is "Moon Hunter's Gaze," which can inflict the "Marked by Moonlight" status effect.
-
Physical Form Phase: After depleting his first health bar, Rerir shifts to his physical form, becoming more aggressive with powerful polearm attacks using his weapon Barnstokkr (also known as Shattered Moon). His attacks gain Abyssal properties that can penetrate shields.
-
Transcendent Phase: At 30% health, Rerir enters his most dangerous phase, gaining the ability to manipulate time and space within the arena. His "Kuuvahki Absorption" ability allows him to heal unless countered properly.
Optimal Team Compositions for the 6.1 Rerir Boss Fight
Since the 6.1 update, the Rerir boss fight has become more technically demanding. Here are some effective team compositions:
-
Pyro-focused team: Utilizing strong Pyro DPS characters can counter Rerir's Cryo resistance during his second phase.
-
Electro-Hydro reactions: Electrocharged reactions are particularly effective during his Phantom form phase.
-
Shield breaker team: Characters with strong shield-breaking capabilities are essential during his Physical form when he creates Abyssal barriers.
Include at least one healer, as Rerir's attacks can inflict continuous damage over time.
Essential Strategies for Defeating Rerir
To successfully defeat the Rerir boss fight in Genshin Impact, keep these strategies in mind:
-
Counter the Moon Marrow absorption: When Rerir attempts to absorb Moon Marrow to heal himself, use charged attacks to interrupt the process.
-
Watch for shapeshifting: During the fight, Rerir may take on the appearance of your team members. The real Rerir will have a subtle dark aura around him.
-
Avoid the Wild Hunt summons: Periodically, Rerir will summon Wild Hunt entities. Prioritize eliminating these quickly as they can buff Rerir if left unchecked.
-
Utilize the environment: The arena contains lunar fragments that can be used to temporarily stun Rerir when activated properly.
-
Save bursts for phase transitions: Rerir is most vulnerable during phase transitions, making it the perfect time to unleash elemental bursts.
