Instead of playing through a scenario from the Scenario Book, players always have the option to play through a random dungeon instead. Random dungeons will not progress the campaign in any way, but they can be used to gain additional experience, money, checkmarks, and personal quest progress for characters.

Each random dungeon consists of three randomly generated rooms and the goal is always to clear all rooms of monsters. The three rooms will be set up one at a time, with the next room only being revealed once the door to it has been opened. Each room is set up using a room card and a monster card, each drawn randomly from the tops of their shuffled decks.

• A noun title (a) When combined with the adjective title on the monster card, this provides the full title of the room.

• A graphical depiction of the map tile(s) used in the setup of the room along with twelve numerical designations of where various elements of the monster card are placed during setup (b). The room setup will also depict any obstacle overlay tiles to be placed. It is possible to run out of specific overlay tiles when setting up the second or third room. In these cases, use a comparable overlay tile of the same type.

• Designations for where players enter (c) or exit (d) the room and what types the entrance(s) and exit(s) are (see below for details).
Entrances and exits always correspond to the nearest half-hex of the tile with a puzzle connection. If this is the first room of the dungeon, players can place their figure on any empty hex within two hexes of the entrance. If the first room has multiple entrances, players can collectively choose on which entrance to start.

• The entrance type available for the room on the back of the card (e). There are two types of entrances and exits: A and B. If players exit a room from an A exit, they must enter the next room from an A entrance and vice versa with B. If the entrance of the top room in the deck does not match the exit the players used in the previous room, the top card is discarded until a matching entrance type is found.

If a room has two exits, players may use whichever one they wish, though the one they don’t use is closed off. If a room has two entrances, players must use the entrance that corresponds to the previous room’s exit.

• Penalties for revealing the room (f). Whenever a new room is revealed and set up, a penalty may activate depending on the room and the difficulty decided on by the players. The suggested difficulty is to use no penalties in the first room, the minor penalty of the second room when it is revealed, and the major penalty of the third room when it is revealed. Players can decrease or increase the number and severity of the penalties as they like, up to a point where major penalties are activated for each of the three rooms when they are revealed. If the character who opened the door is referenced in the penalty of the first room, players can decide who the penalty targets. If the previous room is referenced in the penalty of the first room, nothing happens.

• The specific map tile(s) used to create the room (g).

An adjective title (h). When combined with the noun title on the room card, this provides the full title of the room.

• Designations for the twelve numbered spaces on the room card (i). Each monster has designations for a two, three, and four character game, as in the normal setup for a scenario.

• Descriptions for any treasure tile contents (j). Though treasure tiles in a random dungeon will never contain elements important to the campaign, they can contain a number of useful benefits for the players.

• Designations of trap types (k). Note that the red damage symbol (l) indicates the trap is a damage trap.
