|This is Magical Item is Evil!|
The Glamor, was an evil magical item. It was used in the episode, "The Tale of Jake and the Leprechaun".
InformationIn order for a banshee to survive, every seven years it must make a human being drink this potion. Then to have their victim recite a specific verse, "Turn me now into spirit bright and leave behind the human plight".
The victim has to do this multiple times, for it to fully take effect. Usually, they will trick their victim into drinking this potion. The facade might be something as innocent as just rehearsing a part of a play.
Then soon enough after saying the oath and drinking this potion many times, the victim will be transformed into a small helpless creature, one that somewhat resembles a frog. This is known as a changeling, the banshee is in complete control of it for the next seven years, slowly feeding off the small helpless creature's soul.
