The Hogwarts Legacy The Great Hall Field Guide Pages (all 24) are required to obtain 100% completion in Hogwarts Castle. Each Field Guide Page will grant you 80 XP; as such, if you collect all 24, you’ll get a significant boost and can level up.
Of course, to get the collectibles, you’ll need a couple of spells:
The Field Guide Pages in The Great Hall can be tricky to find, but still, they can be obtained faster than The South Wing Field Guide Pages, which you should also consider looking for.
Where To Find All Great Hall Field Pages in Hogwarts Legacy
The Great Hall area in Hogwarts Castle can be accessed easily by opening the map, selecting the bottom left flag, and fast-traveling to one of the four Floo Flames.
Field Guide Page #1: Near Some Long Tables
The first Great Hall Field Page is near the Great Hall Floo Flame, more precisely, near the long tables to the southeast, as shown in the next image. You need to cast Revelio to make the Page appear, and to pick it up; you must press the / button on your PlayStation/Xbox controller. The Page collectible is named The Great Hall Ceiling.
Field Guide Page #2: On a Stage
The second Guide Page is close to the previous one, on the stage next to the big window to the south. Cast Revelio to reveal the collectible named Owl Lectern and pick it up.
Field Guide Pages #3 & 4: Next to and Above a Statue
Upon obtaining Page collectible #2, go through the bigger door on the west side of the hall, the one with the two braziers. You can see the third Page if you cast Revelio next to the statue in front of you. This Page is named The Yawning Gargoyle. Also, the fourth Page is flying above the same statue. To grab the flying collectible, you must cast Accio while aiming at it.
Field Guide Page #5: Next to a Window
For the next Field Guide Page in the Great Hall area, you have to return inside the hall where you got Pages #1 and #2 and go up the stairs next to the Floo Flame. You’ll soon reach a smaller room where you must climb another set of stairs to spot an unlit brazier next to a window. Cast Confringo on the brazier to light it and reveal the collectible.
Field Guide Page #6: In the Boathouse
Now fast travel to the Boathouse Floo Flame, turn around and go through the door. Use the Confringo spell while aiming at the brazier on the south side of the boathouse to reveal another Hogwarts Legacy Field Guide Page.
Field Guide Page #7: Near a Boat
For the next collectible, go toward the water on the north side of the boathouse and cast Revelio near the boat. Then, pick up the Field Guide Page to find out it’s named Black Lake.
Field Guide Page #8: In Front of a Moth Mirror
Great Hall Field Guide Page #8 will require you to first fast-travel to the Viaduct Courtyard Floo Flame, then go forward without going up the stairs to the right or down the stairs to the left. You’ll soon reach a werewolf statue, and you must go up the stairs next to it to reach a black mirror on the wall.
Cast Lumos near the mirror so that it will display the location where you must find a moth. Now, continue going up the stairs, and you’ll find yourself in a courtyard surrounded by corridors. Position yourself in the middle of the yard, then go to the west passage and head left to find the moth on the wall near a statue. Use Lumos again near the moth to make it follow you back to the mirror.
Field Guide Page #9: Between Two Boats
After getting the previous collectible, head back to the werewolf statue, and from it, go to the southeast door, which is actually an elevator that will take you to the Underground Harbour. Now go on the right side of the harbor and cast Revelio between the last two boats to reveal the ninth Page, named Underground Harbour.
Field Guide Page #10: In Front of Some Sinks
To continue fast travel back to the Viaduct Courtyard Floo Flame and up the stairs to the right. Then, climb another set of stairs to the northeast to reach the courtyard, where you must go through the massive gate to the south to enter the castle. Once inside, immediately turn right, go down the stairs, and go through the door to the left.
Go all the way down the stairs, and you’ll soon have the option to go left or right. Head right, then right again, and go through the door to enter the witches’ bathroom. The tenth Field Guide Page in the Great Hall, named Slytherin’s Sink, is in front of the sinks. To see it and then pick it up, you must first use Revelio.
Field Guide Page #11: Near the Entrance to the Wizards’ Bathroom
Upon picking up the previous Field Guide Page, get out of the witches’ bathroom, go forward, and turn around once you reach the entrance to the wizards’ bathroom. You should now see another black mirror on the wall to the right.
Cast Lumos near the mirror, then go toward the witches’ bathroom, and instead of going in, head up the stairs to the right. Proceed and take the second corridor to the left to find the moth on the column to the right after passing the knight armor. Use Lumos to guide the moth back to the mirror.
Field Guide Page #12: In the Middle of a Small Room
For the next Hogwarts Legacy collectible, you must return to the column where you found the moth for collectible #11. Then, go east until you reach a wooden door with a level 2 lock. To open the door, you need the upgraded version of Alohomora, which is learned during The Man Behind The Moons side quest.
Once you pick the lock, go through the door and cast Revelio in the middle of the small room to reveal the collectible named Detention Chamber.
Field Guide Page #13: In Front of a Wall
Now get out of the small room with Great Hall Field Guide Page #12, go a few meters forward, and use Alohomora again to open the barred door on the right side. Get inside and turn to the right to see a brazier in front of the wall. You know the drill: use Confringo to light the brazier and reveal the next collectible.
Field Guide Pages #14, 15, & 16: Inside a Room With Floating Candles
Head out of the room with the previous Page and go west on the corridor, but keep an eye on the right side for another barred door. Open the door by picking the level 2 lock using Alohomora and go through. Proceed, and you’ll eventually reach a larger room with floating candles.
Page #14, or Headless Hunt Tapestry, is in front of the room’s western wall, and you must cast Revelio to see it. Repeat the process for Page #15, which is in front of the eastern wall. The Page is named Deathday Party Room. Also, Page #16 is up, flying around the floating candles, and to grab it, you must cast Accio while aiming at it.
Field Guide Page #17: In Front of a Wall Half-Covered With Vine
For the seventeenth hidden Field Guide Page, fast travel to the Viaduct Courtyard Floo Flame again and head northeast, climbing two sets of stairs to reach the courtyard. Go to the courtyard’s east corridor, then head south, and when you get to the wall, turn right to see a statue in front of a wall half-covered with vine. Cast Levioso while aiming at the statue to reveal the collectible.
Field Guide Page #18: In Front of a Crest
Now get back to the courtyard from before and enter the castle through the southern gate, then cast Revelio in front of the wall with the crest between the stairs.
Field Guide Page #19: Between Two Red Benches
After obtaining Page #18, go up the stairs to the east to find a statue between two red benches. Cast Levioso while aiming at the statue to make another invisible Field Guide Page appear.
Field Guide Page #20: Flying Above Some Stairs
Now turn around from where you got Page #19, head up the stairs, and look up toward the north to see the next collectible flying around. Cast Accio to pull it.
Field Guide Page #21: In Front of 4 Huge Hourglasses
The next Page takes you through the big door south of the previous collectible. Then, go in front of the four huge hourglasses on the left side and cast Revelio to reveal the House Point Hourglasses Page collectible.
Field Guide Page #22: In Front of a Big Painting
For the next Great Hall Field Guide Page, you must first fast-travel to the Grand Staircase Floo Flame in The Grand Staircase area of the castle. Then, go all the way down the stairs east of the fast travel point to reach a room with red brick walls.
The Page collectible is in front of the bigger painting on the left side, and you need to cast Revelio to see it. The Page is named Pear Portrait, as you’re about to find out when you pick it up.
Field Guide Pages #23 & 24: Between Some Long Tables and in Front of Some Barrels
Now, interact with the big painting previously mentioned to find out it’s also a secret door. Head inside, turn to the right and cast Revelio between the second and third long tables to reveal the Kitchen Table Page collectible. The last Page is in the same room, in front of the barrels on the east side. Cast Revelio to make the House-Elf Living Quarters Page appear, then pick it up.
