Random locations

Random dungeons are new type of content introduced in Underrail version 1.1.1.0.

Mechanics

Random dungeons appear in low level areas to spice up the early game on successive playthroughs.

They do not pop up like random events do. They either are there from the beginning of a playthrough, integrated and continuous with the static map, or they are not. All playthroughs will have at least one random dungeon, rarely up to three. Random dungeons can also be chained so that one random dungeon leads into another.

They should be as indistinguishable from regular areas as possible: A random dungeon will modify one or more zones by adding a small world fragment into the zone that serves as the dungeon's entrance. Usually, any entrance fragment can lead to any random dungeon of matching type (eg. a trapdoor will connect to a ladder, west transition will connect to east transition) but some random dungeons have pre-defined locations.

In addition to random loot like in static areas, every random dungeon has randomized entrances and other varying random factors.
