Below is a walkthrough for the collectibles found during Chapter III: A Burden of Blood in A Plague Tale: Requiem.
Tool
Before raising the gate to leave the city, loot this tool from a chest up the stairs near the crank.
Souvenir: A Grave
After you exit the city, follow the path down to reach a forge. Across from the forge will be a small fenced in area. Follow along the fence to the right of the gate.
This will give you access to hit the lock on the gate with your slingshot. Head inside and interact with the grave next to the house to collect the souvenir.
Hugo’s Collection: Chamomile
When you reach the Herbalist’s garden, head to the back left and look for the tree with a wooden ladder leaning against it.
The flower can be found hanging from the branch to the left of the ladder. You’ll need to hit the lock holding the container the flower is in to cause it to drop.
Secret Chest / Tool
This secret chest is obtained in the depot where you retrieve your sling. It is directly across from where you found your sling and requires 1 knife to open.
This chest will contain a tool!
Souvenir: Our Home
After getting the slingshot, climb up the ladder in the depot to reach the second level. Follow the walkway left to come across a board you can knock down with your slingshot. Cross it then examine the table to find the souvenir.
