After passing through the Collection Room inTales of Arise’s Riville Prison Tower, players will enter an Office. There is a caged bookshelf at the back of this room, which fans can unlock to gain access to a Hidden Chamber.Tales of Ariseplayers will need to do a bit of work before they can interact with the keyhole in the Riville Prison Tower Office, though, and this guide contains full details on exactly what must be done.
How to Get Riville Prison Tower Office Key in Tales of Arise
The first step toward unlocking the Hidden Chamber is to defeat Ganabelt inTales of Arise’s Riville Prison Tower. When that is done, players should make their way to Bregon’s Hideout in Cysloden and speak with Bregon to obtain a sub-quest that is called “Culling the Snowplain.” This quest centers around defeating a series of monster hordes in Neveria Snowplains, and fans will need to return to Bregon when the job is done.

Once “Culling the Snowplain” has been marked as complete, players should speak with Bergon again to start yet anothersub-quest inTales of Arise. This one is called “Survey Says,” and it starts by sending fans to listen to the requests of several Cysolden citizens. Ultimately, these requests will lead players to the Prison Tower cells and a confrontation with a zeugle. Notably, this battle can prove to be slightly difficult if a party is not at a suitable level.
Upon dispatching the zeugle, players will receive an Astral Flower that can be used toincrease CP inTales of Arise. They will also earn the “key to a hidden chamber,” and indeed this is the item that is needed in order to unlock the secret room in the Riville Prison Tower Office. To perform that unlocking, players should simply approach the aforementioned caged bookshelf, interact with it, and agree to using the key to a hidden chamber.

With respect to what players will find inside of the Hidden Chamber, the room houses a container that has a Lucky Bangle in it. This bracelet increases the chance of enemies dropping items, and that effect will certainly come in handy in some instances. That said, players can undoubtedlybeatTales of Arisewithout ever picking up this item, and they should thus feel free to skip unlocking the Riville Prison Tower Office keyhole if it seems like too much effort.
Tales of Ariseis now available on PC, PS4, PS5, Xbox One, and Xbox Series X/S.
