Redwood Observatory as seen on the adventure map. |
Redwood Observatory is an adventure map location which removes shroud within a 20 tile radius around the observatory when it's visited. Even areas clouded by a Cover of Darkness will be revealed, though they will be overclouded again at the beginning of the next day. Although Pillar of Fire exists as an underground variant, Redwood Observatory will still work when placed underground.
Additionally, the Observation Tower added in 深淵號角 is a water variant.
