–Wagstaff, when examining the Spectoggles
The Spectoggles are a Character-specific Hat Item craftable only by Wagstaff. They are found in the Tinkering Tab and require a Gold Nugget and a Pig Skin to craft. They allow a Wagstaff player to remove the blurriness effect due to Wagstaff's nearsightedness. However, when characters other than Wagstaff wear the Spectoggles, the world will appear blurry. They also reveal hidden dangers such as Tentacles.
In the Hamlet DLC, the Spectoggles reveal Nasty Spear Traps and Striking Carvings. In addition, Peculiar Objects can be revealed, allowing Wagstaff to investigate Peculiar Objects. This can be done at no cost to item durability. The goggles also provide immunity to Fog.
