Summary
There are ten missable trophies, each one requiring you to talk to five people at separate times. This is missable because if you don't talk before a certain event, those options will no longer be available. In chapter 12, your Commander Kirkan will tell you to put" something" in the Vault, and right after that, Devin In Palathon, go to ORPHE, SILAS, HAUSER, DAMOLIE, and Belming and click on all talk options with each one. Now, you will only have one option for each NPC; once you click it, the trophies will start to pop up.
