Age Line

The Age Line Spell creates a line that is impassable by people below a set age. It was used by Albus Dumbledore to stop underage students from placing their names into the Goblet of Fire as potential candidates for the Triwizard Tournament. Subjects who attempt to breach the line are repelled, and grow long beards regardless of gender. The Age Line is impassable even by users of an Aging Potion, which was proven when Fred and George Weasley attempted to bypass the Age Line to enter the Triwizard Tournament. Thus, it works for calendar age, not physical age.
