Naga Bromide
From Chrono Wiki, a database for the Chrono series that anyone can edit
The Naga Bromide (also known as Naga-ette Bromide in the SNES/PS version) is a pseudo key item in Chrono Trigger. Oddly enough, it does not appear in the player's inventory when obtained.
The Naga Bromide is obtained in Manolia Cathedral. It can be traded to an old man in Dorino in exchange for a Magic Capsule.
Bromide is a Japanese term for a pin-up photograph of a celebrity. The implication is that the photograph is erotic.
