II. Hunting Experience Display Improvements
1. Hunting Log
The following items have been added to the Hunting Log:
| Display Item | Description |

Base Experience and Bonus Experience have been added as sub-items under “Experience gained per second.”
Experience per second = Base experience per second + Bonus experience per second.
Minor differences in the final displayed figures may occur due to rounding.
III. New Hunting Ground – Arcana Archives
1. Background Story
To preserve magical knowledge and records, the MU Empire, with the help of Arca, built the Arcana Archives deep within the Forest of Aida. A magical Core of Records was created to manage the library, allowing recording tools to operate independently and transcribe knowledge.
As the war against Kundun’s forces continued, vast quantities of war records and dangerous spellbooks were brought into the archives. The Core of Records became overloaded and suffered a critical malfunction. The recording tools incorrectly transcribed spellbooks taken from Kundun’s forces, causing specters sealed within the documents to materialize.
The MU Empire sealed the archives, hoping that the magical energy within the core would eventually run out. Decades later, the gates were reopened, but the core remained unstable and the specters still occupied the library.
Heroes are now tasked with stabilizing the Core of Records and defeating the monsters to reclaim this vast store of knowledge.
