Having a mechanical benefit from torture may mean that you get more torture, and that is not something some of us want in our games. It was bad enough reading about Abu Ghraib, there is just no way I want it in my games.depending on the type of torture CON save can be use too.
How does it sound to use Charisma to prevent giving out information during an interrogation/torture sequence involving the characters as the subject of torture? Most players would simply refuse to give information because they don't feel the pressure of giving the information out without death outright being a consequence. Because otherwise, there's nothing for them to lose.
At first, I was thinking of using Charisma saves because they're being involuntarily pushed to do something that requires willpower to prevent, but then I thought of a skill contest, since the torturer can torture indefinitely, it's up to the character to persuade the torturer that they won't give any information.
So, it would be a Persuasion vs Intimidation check and on success, the character gives out no information during the interrogation and on failure, they share one bit of information.
How does that sound? Too much? Would you enjoy this type of interaction? Would you prefer a different ruling or just let the player decide whether they break or not?
Charisma isn't really "willpower". It's sense of self, soul, or personality.
I would say that Charisma is the ability to project a sense of self or personality, whether you actually have one or not.
This:This is where social interaction could be a form of combat...
If you had a social "AC" so to say, the interrogator would make an "Intimidation Attack" and deal psychic damage. The PC makes a "You can't break me" attack of some sort back, etc. Whoever goes to 0 hp loses and either gives up the interrogation or the information.
Deception is convincing the interrogator that you don't know anything, or providing false information. It doesn't cover just holding out and refusing to talk.This is a flat-out Intimidation vs Deception head-to-head check. Torture is Intimidation, and refusing to give out information is Deception, whether just waking down the street, or tied to the rack. Advantage or disadvantage to one or the other, depending on the circumstances.
