Hey Rox, I was wondering if u could say few things: does Sandrah have like extra lines for certain classes? for example cleric of helm/ilma/talos or bard or like PLD or something else? or some other gems hidden like that?
Those exist in large numbers, either for the PC or for certain NPCs representing some aspects. There are examples for classes/alignement/gender etc. It all happens in the normal cause of events, i.e some events/response options/quests etc will only appear if the conditions are met. Sandrah adapts herself to the PC and the party members. Most likely this will go unnoticed (it is supposed to be only visible if you play the game with her more than once and you see different options under different circumstances).
It is pretty unlikely that you find each and every *hidden gem* or *junk* in a single playthrough.
