In Graveyard Keeper, your main goal is to build a successful business by managing a medieval cemetery. To do this, you need to research various technologies for which science points are spent. To get Science Points / Blue Dots, first, you need to examine and burn the paper in the basement of the church. But for this you need a Church Workbench, which will be your main source of points.
How to create a church workbench
To craft, you need to open Research and Papercraft, which is present in the book writing technology tree. Then create an anvil for making complex iron parts, with which you can make a workbench.
How to use a church workbench
You need to collect human skin, bat skin, or pig skin. Then use the workbench to make Pork Skins out of the leather, then turn them into clean paper. Place the paper on the study chart in the church - there you can study it and finally burn it to get science points.
The above method can be repeated ad infinitum.
Astrologer
