Will-o'-Wisp Lantern

The Will-o'-Wisp Lantern is a trinket that creates a glowing Will-o'-Wisp that hovers near the player and provides light. It is primarily useful for exploring darker areas, since the floating light follows you instead of staying fixed in place.

The wisp has an additional utility in Plains Caves: if there is a Pressure Plate nearby, it will hover over it, which can help reveal hidden treasure chests more easily. The Will-o'-Wisp Lantern can be found in chests in Plains Caves.
