Marium detector

Found at the Hint Shop in Somerset as part of a b-quest

Your retired hero friend gave you this to help track down a stock of marium-infused objects from the sewers. Don't be a princess about getting down there and getting dirty. Only a real toad would blow off a friend in need.

Sorry, I don't have a Luigi joke to round out the quartet.

Unsurprisingly, the benefit of a marium detector is that it detects marium.
