Daun's ordinary life is turned upside down when he is summoned into the Dungeon, where he must play a deadly game, outlasting dangerous monsters and life-threatening traps. To make matters worse, he's only a mere crafter with zero combat abilities. But after Dawoon falls into a trap and survives after a glitched reset, he's gained random but oddly helpful skills. He'll need to get creative to clear the game and return home, with a bloodthirsty assistant and an adorable ground squirrel along for the ride. Now that the rules no longer apply to him, what possibilities await in the tunnels below?
