How to use

Each player begins by taking a starting villain and a hand of room cards. On a turn, players draft or play cards to expand their dungeon, trigger villain effects and set traps that affect incoming heroes. Heroes are drawn or resolved according to game rules and move through dungeon rooms; players compare room effects and rewards to determine which dungeon claims or defeats a hero. The flow alternates between planning hands and reacting to opponents’ layouts until victory conditions are met.

Usage recommendations

For best results, play with 3–4 participants to maximize interaction and competition for heroes. Keep the play area clear for card layout and track rounds to preserve pacing. Younger players may benefit from an initial demonstration game to learn villain abilities and room synergies before full competitive play.
