The Last Story Walkthrough
Chapter 18: Lazulis Castle: Dungeon
Talk to some of your friends. It won’t be long before you’re taken to be interrogated. After the first interrogation, you can talk to the man in the corner to upgrade, or talk to another prisoner in a mask to appraise equipment.
When you feel ready, talk to the man in the corner who sells upgrades a second time. He’ll offer to show you a way to escape the dungeon.
