Seme COM Dungeon: Drururuaga (攻めCOMダンジョン ドルルルアーガ Seme Komi Danjon Dorururuāga) is a game released for Game Boy Color on December 15, 2000 only in Japan. The game takes place 100 years after the events from The Tower of Druaga.
Both the player and the opponent have their own dungeon, each containing five important rooms: the Jewel Room, the Warp Room(s) (amount varies depending of dungeon), and three rooms with a key in each one. The Warp Room allows the players to travel between the two dungeons. The Jewel Room is the starting point, where the Jewel Card is kept locked by a door with three locks, and the first to obtain the opponent's Jewel Card wins. Before the game, the player can place up to 2 creature cards from his deck in each room of his dungeon to protect them without using MP. The player begins in his Jewel Room with 50 MP (with additional MP for remaining deck power not used in the deck) and gains 1 MP per turn. MP is used to pay the cost of Spell Cards to use them, allowing the player to summon more creatures (with a limit of 8 creatures per room), and use equipments and consumable items. The player must go to the opponent's area by using the Warp Room and collect the three keys to open the door in the opponent's Jewel Room. If a player is killed, he will lose equipment cards that are in use and return to his Jewel Room with 0 MP, and will drop one of his cards in the area he died.
