The most important gameplay mechanic in Graveyard Keeper is the technology tree. Thanks to it you can develop your character and complete quests for other characters - without it, you won't be able to complete the game.
You need green, red and blue points to develop the tree. More details on that can be found on dedicated pages of the guide.
Technology tree branches
The technology tree is divided into several branches. They aren't connected with each other. This means that while you can focus on developing only one branch, it may be difficult to do since developing other branches earns you points.
Anatomy and Alchemy
The anatomy and alchemy branch is responsible for all autopsy, exhumation and potion brewing techniques. Alchemy is unlocked after talking to an old woman in the swamps. By unlocking the items in this branch you gain access to better resources and techniques for autopsy, alchemy equipment and raw materials.
Theology is responsible for all the things relating to the church and cemetery. It allows you to unlock better gravestones, slabs and fences. These, on the other hand, are useful for raising the quality of the cemetery. Once the quality of the cemetery has been improved, you will unlock the church in. In it you will gain new church items and be able to preach. This will earn you the blue points to make further improvements in the tree.
This tech branch is concerned with knowledge and science. Its first elements are devoted to the creation of paper, ink and books. This way you will be able to gain more and more points of learning. Thanks to these skills you will be able to preach better, which is connected with the increased inflow of points and cash.
Farming and Nature
This branch focuses on the cultivation of plants, fruit trees, beekeeping, wine and beer production and fisheries. Thanks to these skills you will be able to produce better resources and earn more cash from them. However, if you are developing this branch, it is also worth remembering the Cookery element. It is responsible for creating food, which is much better with good ingredients.
This branch is responsible for processing raw materials such as sand and iron. This will allow you to create much better tools or glass.
This part of the technology tree is responsible for processing raw materials such as rock and wood, so that you can create and repair buildings.
Cookery is a branch responsible for preparing drinks and dishes.
How to develop the tech tree?
To help you grow in Graveyard Keeper, we have prepared some tips on how to develop the skill tree. If you forget about it, the game may take much longer and become much more difficult.
Invest your first points in Building. This will allow you to cut down and process wood. These skills are needed to expand the cemetery and other locations available in the game.
Spend the next few points on a branch called Theology. You will need faith points to develop your character. You will only get them after you get to the church. In order to get to the temple you'll have to repair the whole cemetery first. Thanks to the skills of this branch you will be able to craft new tombstones and slabs, which will improve the quality of the cemetery.
If you're not focused on cooking, forget about Cookery and Farming and Nature. These branches only develop the quality of your raw materials, but if you focus on renovating, extracting and processing your raw materials in Graveyard Keeper, then go to bed when you're done, you don't need to invest in them. Although later quests require wine, you don't have to focus on the farm. You can easily buy wine from Horadric.
After the first week, take care of your Smithing branch. In time, you'll need to use sharper tools for your missions, making sure you're able to craft them.
