Servant Chambers Cathedral Locked Door Key Location
Enter the dungeon through the mausoleum entrance and climb up to the second floor. At the top of the stairs, move forward, and you’ll find another Magla Hollow on your right. It’s a good idea to save here and at every Magla Hollow you come across to ensure you don’t lose any progress you’ve made so far. After that, leave the Magla Hollow and turn right toward the Treasure Chest. You won’t be able to open it just yet since you need the Treasure Chest Key. From there, go through the door on your left, where you’ll encounter more enemies created by the Necromancer.
Take care of the enemies, then follow the hallway to the left. You’ll soon arrive at a large statue in the center of the room. From the statue, go to the left, and you should see a doorway (the others are blocked). Enter that room and defeat the enemies inside to collect some Gilded Cutlery from the table with the candle on it.
Go back outside, and from the statue, head to the right. You’ll encounter the Blue Elementa again. Handle it the same way as before to make it flee, but be careful of the larger enemy roaming the hallway, try to avoid engaging with them if possible. With your back to the statue and facing the larger enemy in the hallway, look to your right and follow the path forward. Then, go through the first door on your right, where you’ll find a Dying Monk leaning against some bookshelves.
To the left of the main door, you’ll also find some Ailment Absolution. Feel free to talk to the Monk if you’d like, then check to their left where you’ll see some barrels. Break the barrels to uncover a small opening in the wall. Go through the opening and find the dead guard on the floor who has a green glowing object next to them. Interact with the guard to collect the Guest Room Key. The Guest Room Key is the key to unlock the Servant Chambers locked doors, which is known as the guest room. To access the Guest Room, use the Guest Room Key. The room is located right beneath the locked treasure chest. You’ll need to go down a short set of stairs to find it.
