We have a kidnapped goblin that we want to be our slave. We want to brainwash him so we don't have to worry about him killing us in our sleep or sneaking off with our stuff. We have access to an iron maiden, rack, and red hot coal pit. How would you handle how to brainwash this dude? I'm thinking it'd be some kind of long skill test.
I don't really think an Iron Maiden, Rack, or Red Hot Coal Pit would be suited for brainwashing. Torture yes, brainwashing no.
Brainwashings goal is to change a persons mental attitude or core belief system towards a defined path. You are going to need psychological and mental stimuli, not really physical stimuli.
The easiest way to run this would probably be through a protracted skill challange that included both stick and carrot approaches and centered on skills like Intimidate, diplomacy, bluff and insight.
Stage 1:
Breaking the individual down to a pliable state, this would probably take between a day and a week depending on the endurance or mental stability of the subject:
Insight - to understand the subjects motiavtion and core beliefs
Nature/Dungeoneering/Arcana/Religion - secondary skills to understand the subject
Intimidate/Bluff - to physically wear them down to reduce their will
Diplomacy/Heal - secondary skills to counter act any negative effects of the treatment and keep the subject in a fit state or in an extreme case
alive.
Stage 2:
Build-up or reprogramming, this would probably take between a week and a couple of months depending on the mental resolve and cultural baggage of the subject. It would also depend on the behaviour you were trying to elicit from the subject.
Diplomacy/Bluff - to assert your intended replacement behaviour model
Insight/Heal - to check that your methods are having the desired effect
Intimidate - to maintain the negative aspect of the subjects previous behaviour
Stage 3:
Monitoring, this would be long term. Probably checking daily, then weekly then monthly depending on the behaviour of the subject. I would also make a mental note that the brainwashing alone will eventually breakdown in some way or other if it is not reinforced through
positive action. Even then it is likely that the trauma will manifest in some other way over time, probably as a psychological effect; nightmares, phobias, aggressive behaviour etc.
Insight - to assess if the subject's new behaviour is set in place or if the subject is breaking its conditioning.
Heal - to make an assessment of the subjects mental health.
Anyway they are my quick ideas, I hope you find them interesting.
