Custom rules that allow you to create trickier dungeons, with a lot of dead-ends.
To use this deck you may need Cavern Edges tiles from The Legend of Drizzt.
Labyrinth deck rules
Whenever you put in play a new tile, draw a Labyrinth card and apply its rules. Do not draw them for tiles with special rules (Chambers, Long Hallway...).
The increased difficulty is balanced by the last rule in the card: if the tile becomes a dead end, do not draw any Encounter card.
The dots allow you to choose how much claustrophobic your dungeon will be!
If you use all cards in the deck, than the chance of having an unexplored edge closed by a wall is 1/2;
if you remove cards with a red dot, the chance will be 1/3, a more "open" labyrinth;
if you remove cards with a green dot, the chance will become 2/3, with a lot of dead-ends and characters going back and forth to find an "exit".
