Secured and secret areas

Underrail rewards exploration and perceptive characters. There are secured and secret areas to be accessed all around. Finding these yields an experience bonus in addition to the loot and other benefits. Discovering secret areas is based on Perception score alone, unlike detecting traps and stealthed characters, which is based on Detection. The Snooping feat helps discovering secrets without high perception.

See Perception for a list of these secrets.
