You’re walking through the snow-dusted streets of Hogsmeade, maybe looking for a new pair of gloves or just soaking in the atmosphere, and then you see her. Penny. She’s a house-elf standing outside a boarded-up shop, looking hopeful and a little bit desperate. This is the start of the Hogwarts Legacy Mind Your Own Business quest, and honestly, if you haven’t played it yet, you have no idea how quickly this game is about to turn into a full-blown psychological horror movie.
It starts simple. Too simple.
Cassandra Mason wants to sell you a shop. It sounds like the ultimate RPG dream, right? Finally, a place to offload your gear for a better price than the local vendors offer. But the moment you step into that basement to "check on some old trunks," the door slams. The lights go out. And suddenly, you aren't playing a cozy wizarding school simulator anymore. You’re trapped in a shifting, sentient nightmare designed by a poltergeist named Fastidio who really, really hates visitors.
The PS5 Exclusive That Finally Went Global
For a long time, this was the "forbidden" fruit of the wizarding world. If you played on PC, Xbox, or Switch at launch, you were basically locked out of the best content in the game. Sony had a death grip on this quest for a full year. It wasn't until the Summer 2024 update that the rest of the world finally got to experience the sheer anxiety of being chased by wooden mannequins in a dark basement.
It’s worth the wait, though.
Most side quests in this game are "go here, kill three spiders, bring back a mushroom." This one? It’s a 45-minute gauntlet of puzzles and jump scares. It feels like the developers at Avalanche Software took a break from the main story and decided to see how much they could freak out the player base. The tone shift is jarring, but in a way that makes the world feel way more dangerous and alive.

Why Fastidio Is the Real Star
Peeves is fine, sure. He’s a classic. But Fastidio is something else entirely. He doesn’t just prank you; he attempts to shatter your perception of reality.
As you navigate the Hogwarts Legacy Mind Your Own Business dungeon, the rooms change when you turn your back. You’ll walk through a door, turn around to go back, and find a solid brick wall. Or worse, a room full of those creepy, twitching mannequins that only move when you aren't looking at them. It’s a direct nod to the Weeping Angels from Doctor Who or the mannequins in Silent Hill, and it works perfectly within the magical context of the game.
The boss fight at the end is equally chaotic. You aren't just fighting a monster; you're fighting the environment. Fastidio hurls furniture, creates illusions, and mocks you the entire time. It’s one of the few moments in the game where your mastery of spells like Lumos and Revelio actually feels like a survival mechanic rather than just a way to find hidden chests.
Breaking Down the Shop Mechanic
Once you survive the trauma—and it is a bit of a trauma—you actually get what was promised. You own a shop in Hogsmeade. You get to name it (I went with "Stitches and Draughts," but "The Vesters and Venoms" is a solid choice too).
Here is the real mechanical value:

- Better Sell Rates: You can sell your gear here for a 10% markup compared to any other vendor in the game. Over the course of a full playthrough, that adds up to thousands of extra Galleons.
- Penny the House-Elf: She stays at the shop to manage things while you’re off saving the world or accidentally turning leeks into rabbits.
- Cosmetic Rewards: You get the Shopkeeper’s Outfit, which is easily one of the sleekest, most "adult" looking sets of gear in the game. It makes you look like a legitimate business person instead of a student who spent the night sleeping in a swamp.
Navigating the Library and Atrium Puzzles
Don't go into this quest under-leveled. Not because the combat is impossible, but because the puzzles require a lot of back-and-forth movement that can get tedious if you’re frustrated.
The quest is split into two main wings: the Library and the Atrium.
In the Library, you’re dealing with disappearing floors and ladders that lead to nowhere. You have to find lanterns and place them on hand-shaped stands to unlock doors. It sounds straightforward until the lights go out and the mannequins start appearing in the doorways. Pro tip: keep Lumos active at all times, but be prepared for the game to forcibly turn it off to mess with your head.
The Atrium is more about combat and spatial awareness. You’ll be fighting waves of animated furniture and mannequins while the room literally rotates around you. It’s dizzying. It’s brilliant. Honestly, it’s the kind of creative level design I wish we saw more of in the main campaign.
The Moral Grey Area of Cassandra Mason
Let's talk about the ending. Without spoiling the exact dialogue, you eventually confront Cassandra Mason. The woman who basically tried to have you murdered by a poltergeist so she could keep your money.

The resolution of Hogwarts Legacy Mind Your Own Business is satisfying because it doesn't just end with a "sorry about that." You get to involve the local law enforcement, and there’s a real sense of justice. It’s one of the few times in the game where your actions have a visible, permanent impact on the Hogsmeade community. Seeing the shop open and thriving later in the game feels like a genuine accomplishment.
How to Prepare Before You Start
If you’re seeing the quest marker on your map, don't just rush in.
First, make sure you have plenty of Wiggenweld Potions. You're going to take chip damage from environmental hazards, and the final fight has some high-damage phases. Second, clear out your gear inventory. Since the reward is a shop where you can sell items for more money, you want to have a backlog of expensive "Legendary" gear ready to go the moment you sign the deed.
Also, maybe play this one with the lights on.
I’m serious. The sound design in the basement is incredible—lots of scratching, whispering, and footsteps right behind you. It’s a masterclass in atmosphere that feels distinct from the rest of the game’s whimsical tone.
Actionable Steps for Players
If you're ready to tackle this, follow this sequence to maximize your efficiency:
- Trigger the Quest: Locate Penny near the South Hogsmeade entrance. You need to have progressed far enough in the main story (specifically, you must have completed the "Fire and Vice" quest).
- Hoard Gear: Stop selling your gear to vendors like Gladrags for a few hours before you start. Save those high-value items for your own shop.
- Spell Loadout: Equip Lumos, Accio, Levioso, and your strongest offensive spells (Confringo or Bombarda). You’ll be swapping between utility and combat constantly.
- The Lantern Rule: If you’re stuck in a room, look up or behind furniture. There is almost always a lantern hidden just out of your immediate line of sight.
- Claim Your Profits: Once the quest is over, make it a habit to return to Hogsmeade every time your gear slots are full. The 10% bonus is the most consistent way to get rich in the endgame.
This quest stands as a reminder that Hogwarts Legacy is at its best when it leans into the weird, dark corners of the wizarding world. It’s not just about the school; it’s about the ancient, sometimes cruel magic that sits right beneath the surface of everyday life.
