That's why the Warlock Restaurant on the surface is so popular—because transporting usable cooking ingredients up from the deeper layers of the Dungeon is anything but easy.
And for that very reason, the Dungeon has become a place countless people flock to.
Here, even a greenhorn fresh out of the nest, as long as they're willing to swing their weapon and fight steadily, can earn enough to make a living; and for the strong, there's no need to waste effort handling the corpses of Magic Creatures—they can just directly take the most essential parts.
By contrast, on the surface, Adventurers may spend days wiping out a band of Goblins and still walk away with nothing, while in the Dungeon, no matter how weak a Magic Creature is, as long as you hunt it, there's some gain.
