Item: urn of Hi-Res Root Beer, granting creatures that drink it the ability to see and hear digital files in greater resolution

Just the thing for your urban high fantasy campaign that draws on both “Dune” and modern police procedurals, in which various organizations compete over control of a substance that lets “zoom and enhance” actually work

Item: monster bait hat, attracting all dumb and carnivorous monsters once it’s within line of site. By some unfortunate curse, it only works when worn by a sapient character, so no cheating by just leaving it lying around.
