Peep

Peep is a spell in the Dragon Quest series. Introduced in Dragon Quest III, Peep was then learned by Wizards but has since extended to a less narrow range.

Peep is a field spell that was introduced alongside the monster that gave worth to the spell: Mimic. Casting Peep will determine whether or not a treasure chest is safe and, in later installments/reprises, can be used to appraise items.
