Snoop is a recurring spell in the series that casts a bright glimmer on hidden objects in a dungeon, giving the player an easier time finding them. The spell is nearly exclusive to thieves, with the exception of old man Borya, and costs a mere 2 MP in every appearance.
Dragon Quest III remakes
Thieves will learn to cast snoop at level 20. Several Mini medals are hidden in unassuming areas with no attention-grabbing landmark, making the spell a serious boon for players who like to collect the trinkets.
Dragon Quest IV remakes
Borya will learn the spell at level 23 in the Playstation version onwards.
A thief will learn the spell upon reaching rank 8.
Players can learn snoop by getting a character to rank 5 of the Pirate vocation in the playstation version, and to rank 5 of the thief in the 3DS remake.
