If two of the player's dice land on Summon Crests, they may place one of those which landed on a Summon Crest on the board in such a way that when it unfolds, it connects to their dungeon. The six sides of the dice are added to the player's dungeon and the monster inside is placed in their dungeon on one of the die's squares.
When a rare black die is unfolded, its special square contains an item, which monsters can interact with.
Non-Summon Crests rolled by the player are stored in their crest pool.
Each Movement Crest can be used to move a monster one space.
Attack Crests can be used to attack monsters in adjacent squares.
Attack, Defense, Movement, Magic and Trap Crests can be used as costs to activate monsters effects.
When a monster attacks another, the one with lower ATK is destroyed.
Each time a Dungeon Master is attacked, it loses a Life Point. When the Dungeon Master loses all its Life Points, its controller loses.
