- Firelink Shrine
- Profaned Capital
- Lothric Castle
- First proceed through the Grand Archives until reaching the shortcut lift near Lorian and Lothric. This lift consists of two parts, similar to the one found in the Undead Settlement. Ride the lift down, which takes one outside of the Dragonslayer Armour bonfire, and once there make it go up again; the other part of the lift will arrive from below. Ride it down to find a corpse in a small niche holding the slab.
- Grand Archives
- From the Grand Archives bonfire, proceed through the first section of the level until reaching the large vat filled with wax (make sure to dip the head inside to cover the head with it). Once reaching the third floor, after exiting the darkened room, look for a lever located between two bookshelves in the front and pull it (the wax will prevent all damage inflicted by Clawed Curses). A bookshelf will be seen moving below and to the left. Return to the second floor and, from the vat with wax, head straight to find a new passage where the bookshelf moved. A chest containing the slab can be found inside.
- Obtained by defeating the three Gertrude's Knights guarding the top the archives' main dome.
- Archdragon Peak
