How To Find The Undercroft In Hogwarts Legacy

If you are playing on PC, PlayStation 5, Xbox Series X|S, or Nintendo Switch, finding this room is a rite of passage. But because it lacks a dedicated fast-travel point, many players find themselves wandering the Defense Against the Dark Arts Tower aimlessly, trying to remember which suit of armor or staircase leads to the entrance. Whether you are looking for a place to practice Wingardium Leviosa on old barrels or you're following the dark and twisting path of the Gaunt family, this guide will show you exactly how to get there.

The Origin of the Mystery: Why is the Undercroft Hidden?

In the lore of Hogwarts Legacy, the Undercroft isn't just a dusty basement. It is a family secret. Known to the Gaunt family for generations, this space has been used by Ominis Gaunt and the Sallow twins, Sebastian and Anne, as a private hideout.The reason the Undercroft is so difficult to find is twofold:

• Narrative Locking: The game prevents you from interacting with the entrance until you have reached a specific point in the story. You cannot stumble upon it by accident during your first week at school.
• Lack of Floo Flames: Unlike the Room of Requirement or the Map Chamber, the Undercroft does not have its own Floo Flame. This means you must manually navigate the castle every time you want to visit.

Quick Solution (For Impatient Witches and Wizards)

If you have already unlocked the room and just need a quick refresher on how to get back:

Fast travel to the Defense Against the Dark Arts Tower Floo Flame.

Walk down the stairs to the right.

Locate the large horned creature skeleton.

Follow the direction the skeleton's horn is pointing toward the dead end.

Interact with the ornate wooden cabinet against the wall to enter.

Detailed Step-by-Step Solutions

Navigating Hogwarts can be dizzying. Here is the comprehensive breakdown of how to reach the Undercroft through various methods and story beats.

Step 1: Meet the Prerequisites

You cannot enter the Undercroft whenever you like. You must first trigger the quest "In the Shadow of the Undercroft." This is the 18th main story quest and becomes available immediately after you finish "The Room of Requirement" mission. If the quest hasn't appeared in your log, keep progressing through the main story.

Step 2: Use the Field Guide Navigation

Once the quest is active, use your Compass Path. Press Up on the D-Pad (Consoles) or V (PC). A golden trail of magical dust will appear on the floor, leading you directly to the Defense Against the Dark Arts Tower in the Astronomy Wing.

Step 3: Finding the Landmark (The Skeleton)

The key to finding the Undercroft is the Skeleton of a Large Horned Creature.

• From the Defense Against the Dark Arts Tower Floo Flame, head down the first set of stairs.
• Stick to the right side of the banister.
• You will see the skeleton prominently displayed.

Step 4: The Horn "Compass"

Look closely at the skeleton. The large horn on its head points directlytoward a secluded corner of the hallway. Follow that direction to theleft of the nearby staircase. You will find yourself at what looks like a dead end with a tall, magical cabinet.

Step 5: Entering the Room

Walk up to the cabinet. If you have the quest active (or have completed it), an interaction prompt will appear. Your character will step inside, and after a brief loading screen, you will be inside the Undercroft.

Variation: Accessing from the Transfiguration Courtyard

If you are coming from the ground floor:

1. Fast travel to the Transfiguration Courtyard Floo Flame.
2. Enter the large double doors leading into the Defense Against the Dark Arts Tower.
3. Walk up the stairs and turn left.
4. You will see the skeleton from the opposite side; follow the horn's direction to the cabinet.

The Secondary Secret Entrance (Isadora Morganach's House)

Much later in the game, during the quest "In the Shadow of the Estate," you will discover that the Undercroft is connected to the world outside Hogwarts.

1. Travel to Feldcroft: You will explore the ruins of Isadora Morganach's house with Sebastian.
2. Locate the Cellar: Enter the ruins and duck under a hole in the crumbled wall. Follow the stairs down into the cellar.
3. Clear the Path: You will see a wall of old shelves. Use your basic cast (normal attacks) or Depulso to break them apart.
4. The Mirror Portal: Behind the shelves is a triptych mirror. This acts as a secret passagethat teleports you directly back into the Undercroft in Hogwarts.

Pro Tip: While you are in Isadora’s cellar, be careful of the Devil’s Snare plants. Keep your wand lit with Lumos to keep the vines at bay while you explore.

How to Prevent Navigation Frustration

Since the Undercroft is the only major "hub" area without a fast-travelpoint, it can be annoying to find. To make your life easier:

• Don't Forget the Skeleton: Always remember that the skeleton's horn is your "North Star." If you find the skeleton, you’ve found the room.
• One-Way Limitation: Note that the mirror in Isadora's house is a one-way trip. You can go from the house to the Undercroft, but you cannot use the Undercroft to teleport back to Feldcroft.
  • Practice Area: Use the Undercroft as a low-stakes area to practice combo spells. Thebarrels in the room respawn, making them perfect targets for Accio and Levioso practice.

  Frequently Asked Questions

  1. Can I enter the Undercroft before the quest starts?No. The cabinet will appear as a decorative object and will not providean interaction prompt until Sebastian Sallow invites you there duringthe "In the Shadow of the Undercroft" mission.

  2. Is there a Floo Flame inside the Undercroft?Unfortunately, no. The closest fast-travel point is the "Defense Against the Dark Arts Tower" Floo Flame in the Astronomy Wing.

  
  

  3. Why can't I see the mirror portal in Isadora's house?The mirror portal only appears after you have progressed significantlyin Sebastian Sallow’s questline. If you visit the house early in thegame, the cellar will be empty of magical portals.

Conclusion

The Undercroft is more than just a room; it’s where the most compelling parts of the Hogwarts Legacy story unfold. By mastering the route from the Defense Against the DarkArts Tower and utilizing the skeleton landmark, you’ll be able tonavigate the castle like a true Gaunt descendant.
