An Ocuvigil is a Don't Starve Together exclusive Structure, introduced in A New Reign. It is found in the Magic Tab. It requires a Purple Moonlens, a Compass and 2 Boards to craft, and a Prestihatitator to prototype. It is used for revealing the fog of war in a certain location to all players, as well as serving as a Map marker.
- It is referred to as "sentryward" in game files, a structure with the same name and function exists in multiple mobas.
- It used to be crafted with a Yellow Moonlens, that was replaced by a Purple Moonlens in a later update, as Yellow Gems are not easily available in worlds without Caves.
