The item is used to improve the Hammer and Chisel and unlock the second skill. We’ll tell you where to find it.
To upgrade the Hammer and Chisel a second time, you will have to find another hidden object. To do this, you need to get to the archives. Don’t rush to go to the boss! At the beginning of the archives, on the left behind the bookshelves, find a portal that will lead you to the top of the location. There is hidden Censer around the corner.
