Couldn't you raise it in the Arman quest or am I mistaken?
Yea, but I'm just asking that there be more instances like that. It'd also be nice to know when it happens. Even knowing that you failed to increase it would be cool. I guess this aspect of the game is kind of complicated:
For instance, how high does personality need to be? It's the one trait where you can't see the immediate difference when you upgrade it.
In Telepath 2, personality was pretty simple. Apart from adding slots for the team, I think the only place you needed it was to be able to buy bonds. There weren't any missions where it mattered.
