I went ahead and refreshed the data, so database.valkyrieuprising.com should have up to date information. I will try to keep my database updated with monsters, items, and pets.
The information itself is ripped from data files in the client, and some of it seems like it's duplicate (one version in english, one in korean). So the site may have some duplicate information.
As for new features or functionality, I don't play ROVU anymore and unfortunately I don't have much time available to dedicate to improving the database functionality. Seeing as rovu.info is going to shut down, I will try to at least keep the database refreshed with items, monsters, and pets.
