The Minding Your Own Business side quest stands out as one of the most intriguing and atmospheric adventures available in Hogwarts Legacy. Players begin this quest in Hogsmeade by speaking with Penny, a house-elf standing outside a vacant shop near the southern edge of the village. What starts as a simple commercial transaction quickly evolves into a psychological horror experience filled with mind-bending illusions and tricky puzzles.

Purchasing the Hogsmeade Shop

To start your journey toward owning a shop, you must first speak with Cassandra Mason to negotiate the purchase price of 1,500 gold coins. Once you secure the funds and acquire the key, you return to Penny to begin cleaning up the premises. Entering the back room leads to the discovery of a mysterious chest that drops you into a hidden subterranean dungeon.

Navigating Fastidio's Haunted Dungeon

Inside the underground maze, players encounter Fastidio, a troublesome poltergeist who takes delight in creating eerie psychological trials. You will encounter shifting hallways, illusionary doors, and unsettling groups of animated mannequins that move whenever the lights go dark. Progressing through the dungeon requires solving light-based puzzles by manipulating lanterns with Wingardium Leviosa and navigating both the Library and Garden routes.

Confronting Cassandra Mason

After surviving Fastidio's antics and defeating his wave of animated furniture, you return to the surface to confront Penny about the trap. Discovering that Cassandra Mason set up the entire ordeal, you report the situation to Officer Singer and prepare for a magical duel. Defeating Cassandra in combat permanently clears the title for your new property and resolves the haunting.

Unlocking Your Shop Rewards

Completing this memorable quest unlocks exclusive rewards, including the Shopkeeper Cosmetic Set and your very own shop in Hogsmeade. Players can name their business and sell extra gear to Penny at a higher profit margin than standard vendors in the village. This engaging quest delivers a unique mixture of horror-infused exploration and valuable gameplay benefits for ambitious witches and wizards.
