The South Sea Bog Field Guide Page is a Hogwarts Legacy collectible that will get you 80 XP, and it’s mandatory if you want to achieve 100% completion in the swampy area. The only requirement to obtain the collectible is to have the Revelio spell unlocked.
However, the Field Guide Page in South Sea Bog is invisible, and you can miss it even if the swampy region is pretty small.
Where To Find the South Sea Bog Field Page in Hogwarts Legacy
On the following South Sea Bog map, I’ve pinpointed the location of the Field Guide Page. As you can see, the collectible is found in the middle of the region, south of the Northern South Sea Bog Floo Flame.
The fastest way to get to the location marked on our map is to fast-travel to the Northern South Sea Bog Floo Flame, provided you have it unlocked. If not, track the spot on your map and head there on your Hogwarts Legacy flying Broom. Look for a house half underwater next to two wooden bridges. When you see the house, go in front of the door and cast Revelio to reveal the South Sea Bog Field Guide Page.
Then, approach the collectible and pick it up by pressing the Square/X button on your PlayStation/Xbox controller. You can now see that the Field Guide Page is named Abandoned Bothy, as in the following screenshot.
