Wondrous Item, very rare
An ornate monocle that when worn causes the wearer to believe that they are more intelligent then everyone currently around them. This compels the wearer to educate, inform or correct any piece of information no matter its actual accuracy.
This can actually be really useful. i see it as a zone of truth spell on the wearer. if a party forced it onto someone they want to interrogate and started making false assumptions then the person would correct them with the right information.
Lol!
