Osse is one of the most unique and intriguing NPCs in Genshin Impact, playing an essential role in the Fontaine region’s Canticles of Harmony world quest before becoming a beloved regular NPC. Introduced in version 4.6 alongside the new Nostoi Region, Osse initially serves as the vessel for Cassiodor’s spirit, a prominent figure in the storyline. As players progress through these quests, Osse’s role evolves from a supernatural entity to a cherished cat companion. This comprehensive guide covers everything you need to know about Osse, from origin and quest involvement to post-quest interactions and achievements.
Osse – Origin and Role in Genshin Impact
Osse is originally introduced as a cat serving a mystical purpose in Fontaine’s Nostoi Region. Players first encounter Osse during the Canticles of Harmony world quest, where they learn that it acts as the vessel for Cassiodor’s spirit. The presence of this spirit transforms Osse into a significant character, altering its behavior and visual appearance.
Once the Canticles of Harmony quest concludes, Cassiodor’s spirit departs from Osse, turning it back into a regular cat NPC. However, Osse remains an important character, as it can be interacted with even after completing the main storyline.
Osse – Appearance and Behavior in Canticles of Harmony
During the Canticles of Harmony world quest, Osse exhibits noticeable visual changes due to being possessed by Cassiodor’s spirit. Players can identify Osse by its necklace and glowing Symphony marks on its body. These unique features distinguish it from other animals in the region.
While players can pet Osse during this phase, it only responds positively when petted in specific areas:
- Forehead – Osse enjoys gentle head scratches.
- Back – Light strokes along the back elicit a calm response.
- Chest/Pendant – Touching its necklace area is also preferable.
- Legs – Gently tapping or scratching its legs is acceptable.
However, some areas do not yield positive reactions:
- Tail – A sensitive spot that Osse dislikes being petted.
- Ears – Causes an indifferent or negative reaction.
- Paws – Osse does not appreciate touching in this area.
Osse – Post-Canticles of Harmony Changes
Upon completing the Canticles of Harmony questline, Osse reverts to a normal cat NPC. However, it receives a new name from Paimon – Monsieur Os. While Osse no longer displays supernatural characteristics, it remains an interactive NPC that players can visit.
Osse – Role in the Quest “For Yesterday and Tomorrow”
Osse’s story continues in For Yesterday and Tomorrow, the follow-up quest that provides closure to its journey. In this quest, players are responsible for ensuring Osse’s safety by bringing it to the cattery located in Petrichor.
During this quest, players guide Osse to its new home, ensuring it is well taken care of. The storyline provides a heartwarming conclusion by allowing players to reconnect with Osse even after the primary quests.
Once the quest is completed, Osse officially becomes a resident of the cattery, offering additional interactions for those who wish to visit their feline friend.
