You now need to craft a Book Binder, made with 5 wooden planks in the bottom two rows, leaving the bottom center slot empty, and three iron ingots in the top row. With a piece of leather in the left-hand slot of the Binder, and paper (single/multiple) placed in the large rectangle directly underneath that slot, the Descriptive book is output in the right-hand slot. Alternatively, if you've had the fortune to find many Symbol pages in Villages, Dungeons etc. then you can use those instead of paper, or place them into your notebook. Once in your notebook, by placing paper in your writing desk, and Right-Clicking the symbol you wish to copy, you can replicate symbol pages you already have. Without any symbol pages, the Descriptive Book symbol generation is random and almost always Unstable.
