Scrolls of punishment are randomly generated with the same probability as all other 300zm scrolls. 1.5% of all randomly generated scrolls are scrolls of punishment.
Wizards and monks may start with an identified scroll of punishment: the scroll is not 100% bad because the iron ball is useful.
It is expensive, so when unidentified, less careful players might mistake it for the scroll of genocide or the scroll of stinking cloud. When blessed, this scroll is harmless; you only get the message "You feel guilty".
The scroll self-identifies when you read it.
|"You feel guilty."||The scroll was blessed, or you were confused|
|"You are being punished for your misbehavior!"||The scroll was uncursed or cursed|
|"A ball and chain appears, then falls away."||You were punished, but the chain couldn't be attached to you|
It has been said that the best thing about the scroll of punishment is its resale value. Aside from that, you probably want to use these for blanking.
See punishment for why being punished may be desirable. Short version: it isn't, except as makeshift weapon before you see anything else, or some corner cases involving jumping.
