About the game
The Seven Deadly Sins descend upon the Otherworld, manifesting as psychological horrors that corrupt the wanderers with their unique depravity. Replacing the abominations, they unleash new mechanics and unprecedented challenges to the wanderer stage. Replacing the abominations, the Sins unleash new mechanics and unprecedented challenges to the wanderer stage. You need not and cannot kill the Sins. However, this does not mean victory will come easily. Each Sin offers a unique, immersive gameplay experience reflecting its twisted essence. With streamlined, straightforward rules and more accessible mechanics, the Sins provide deep, thematic interaction while reducing playtime and minimizing bookkeeping compared to the core game’s abominations. This change allows players to focus more on experiencing the narrative and surviving the Otherworld’s horrors. Each of this expansion’s Sins is paired with a unique Sin die – ranging from a 4-sided die to a 100-sided die – creating a complete set of seven distinctive dice. The Sins also feature selectable difficulty levels determined by their die faces’ numbers. Gluttony, represented by a 4-sided die, is the easiest, while Pride offers the steepest challenge with its imposing 100-sided die. Players can freely choose their difficulty based on their preferred level of tension and mood. —description from the publisher
