Trivia[ | ]
- It's effects are unknown.
- It has been in the game files since at least August 2016 in addition to the Trapple and the Detention power, fuelling speculations of a teacher-themed Killer.
- The icon for this perk looks like a child wearing a "dunce cap." It was usually used as a form of punishment in schools. This gave even more of an indication to a potential Teacher as Killer.
