In Dragon Quest IV, to get into the house at Diabolic Hall, you need to progress through the story until you obtain the key item called the "Magic Key." This key allows you to unlock certain doors throughout the game, including the one at Diabolic Hall. Once you have the Magic Key, simply approach the locked door and use it to gain entry. Inside, you'll encounter various enemies and treasures as part of your adventure.
These would be placed in a Quest Hall.
