Ah, great idea.
No lockpicks but still able to getting out of prison with attached restraints, or able to struggle for spending HP would be cool.
I will positively consider your suggestion. Thank you.
Another possible option while Nesche is chained up with no lockpicks is to wait and eventually one of the dungeon inhabitants will come by to ravish/abuse Nesche. After that occurs, there is a chance a lockpick will appear in her inventory. Maybe a bit of dialogue of how the stupid orc dropped it while molesting her.
There is still the danger of Nesche starving and/or taking damage from the abuse so still could lead to a bad end. Yet another option is for a "give up" button which when selected will lead to the bad end. In this case, the abuser could instead feed Nesche if her health is low, to allow for continuous play.
