The Minding Your Own Business side quest in Hogwarts Legacy stands out as one of the most memorable and unique adventures in the game. Originally available as a console-exclusive mission, this quest blends eerie psychological horror elements with intriguing puzzle mechanics. Players looking to establish their own business in Hogsmeade must first navigate a sprawling, shifting labyrinth hidden directly beneath the village.

How to Unlock and Begin the Quest

To initiate this quest, players need to reach character level 20 and complete the major story milestone Fire and Vice. Once these prerequisites are met, speak with Penny the house-elf outside the vacant shop located in southern Hogsmeade. She will direct you to Cassandra Mason, who offers to sell the shop property for 1,500 gold coins.

After acquiring the shop, return to Penny to clean up the interior using the Reparo spell. Penny will then hand over the key to a mysterious chest located in the back room. Opening this chest uncovers a hidden ladder that leads deep into a dark subterranean dungeon.

Navigating Fastidio's Mind-Bending Labyrinth

Upon descending into the cellar, you are trapped inside an enchanted realm governed by a playful poltergeist named Fastidio. Escaping requires solving environmental puzzles, maneuvering floating lanterns, and navigating changing rooms that alter when the lights go out. You will need to utilize spells like Lumos, Accio, and Wingardium Leviosa to open hidden pathways.

Along the way, players must face combat encounters against swarms of creepy possessed mannequins and dodge flying furniture thrown by the poltergeist. Completing both the Library and Atrium sections allows you to confront Fastidio directly in a multi-stage boss encounter. After enduring his tricks, the poltergeist agrees to let you leave through the mausoleum exit.

Confronting Cassandra Mason and Quest Rewards

Once back on the surface, report Cassandra Mason's deception to Officer Singer in the Hogsmeade town square. Accompanying the officer to confront Cassandra triggers a intense boss fight against the fraudulent seller. After defeating her, Officer Singer arrests Cassandra and transfers full legal ownership of the shop and Penny over to you.

Completing the quest yields substantial rewards, including the Shopkeeper Cosmetic Set containing themed attire like the Shopkeeper's Coat and Top Hat. Most importantly, you unlock your very own Hogsmeade shop where you can sell unwanted gear to Penny at a higher profit margin than standard vendors. This rewarding endeavor provides a great long-term source of gold for your journey.
