The underworld jungle - a place of grim reputation, source of many legends and superstitions. The deepest reaches of the caverns of Underrail. Home to the Tunnelers, also known as the Faceless.

Cytosine Outpost — A small tchortist outpost with an elevator connecting it to Underrail far above it.

Black Sea

This page contains content from Underrail: Expedition expansion.

Added in Underrail: Expedition expansion, Black Sea is a vast body of water in the northeast, a real underground sea. Avoided by most captains, these infamous waters and shores are home to pirates and worse.

Secret areas

Underrail rewards exploration and perceptive characters. There are secret areas to be accessed all around. In addition to the loot and other benefits, finding these yields an experience bonus in classic XP mode. 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.
