Tech tree
The research tree as the game lays it out: five branches, read left to right. Building, Metallurgy and Farming open on waking up at home in the intro; Theology opens during the quest Holy Moly!; Anatomy and Alchemy opens on placing the first body on the autopsy table. Each technology costs red, green and blue tech points, earned through actions and by studying new items at the Study Table, and needs every technology connected to it on its left. The Cooking tab holds 20 dish groups that cost no tech points.
Hand-crafting skill and working with materials.
Knowledge of nature and of the nature of things.
Spiritual knowledge of the immaterial world. The first blue point comes from the Study Table in the church basement.
A character's portrait in the tree: it opens once the research before it is done and the reputation with that character reaches the value shown.
Building holds 52 technologies over 18 columns, read left to right like in the game. Researching all of it costs 4,470 red, 257 green and 670 blue tech points. 2 reputation gates sit in this branch. The tab opens on waking up at home in the intro.
