May I ask what Darian's "hidden" personality trait is? I tried doing it exactly the way you showed, but unfortunately, nothing shows up for me just some weird stuff. And I’d rather not start experimenting around. That never ends well for me.
Hang on let me check if the information is still floating around in the 1.7.0 level0 file. I technically revealed this before, but I didn't know it was for Darian at the time. If it's been hidden since, I'm not going to reveal it, otherwise, might as well.
Also, you can find this out if you spend any significant length of time with him. I even saw signs of it before I put the two things together.
Right, so that information isn't uncompressed anymore, so you won't see it in the files, which means I probably shouldn't share it, since it's not publicly available knowledge. I suspect it's set knowledge, so if you mod Darian it will still be a hidden part of his personality because anything new is appended to the existing knowledge pool.
