Perhaps for harsher punishment, something like detention or in school suspension could be implemented? It def would not have to follow the regular versions of those things. They could be way harsher since this is a hell school lmao. Whether that means going through a personalized trial, solitary confinement, or maybe something else, that might be something to balance out the act more!

Scapegoat mechanic def sounds fun! I think punishment might need be considered for it too though. Like maybe in addition for opt-in, maybe a choice for light punishments would be good too. Or at least a opt-out choice for one of them or something.

Reward wise, merit-points and small prizes would be great! I think reduced prices on bonus AC would also be great too! Doesn't have to be a ton, but I think that's good incentive and you can be selective on what would be reduced.

Anyway all just ideas; none need to be taken but they can be changed too as you best see fit! If you wanna run anything by me I'm all ears!
