At this point we have learned about the following oaths. There are likely others, such as those spoken in a courtroom (imagine how much the justice system could be simplified if we had magically binding oaths. A simple "did you do it, yes or no", under magically binding oaths to say the full truth, would pretty much eliminate wrongful imprisonment ). 1) Favor. Thrice heard and witnessed, it binds the speaker to do a service on behalf of whoever holds the other end. Richter owed one to a demon, now replaced by a quest. 2) Fealty. Sworn by the villagers to Richter. The kindir will most likely swear a similar oath 3) Bloodoath. Time limited, 1 year. After that a cost of one charisma per week, permanent loss. Likely other punishments if the first isn't enough or Richter hits 0 charisma. Apart from the bloodoath having special time constraints, I think its likely the system of fighting holds for all types of oaths and not just favors, meaning that if you break an oath you face the other party in a duel that might bring about extra punishments. After that you'd still face the hit to reputation, fame, relationships and so on. Pretty weighty reasons to keep your word. In the case of chaos seeds, would they lose their chaos points and have their extra lives/ enhancements/ abilities reduced to their value in chaos points? Perhaps not all of it depending on the severity of the breach and how much they lose the duel, but at least part?
