Laboratory I
Already in place in Alchemy Lab, so you do not need to build it.
A Laboratory I is the alchemy table with two ingredient slots. You put in up to two studied ingredients, and if their runes add up exactly to a known or unknown result, working the table makes it; Alchemy explains the runes, flasks and results. One already stands in the tower laboratory when it opens, so you do not need to build your first. More can be built from the laboratory’s build desk, for 4 Wooden Planks, 3 Bronze Details and 3 Glass, with Alchemy, Basic, which the Plague Doctor gives you.
Notes
- Six results need three ingredients, among them Reanimation Liquid. For those you need Laboratory II.
- Building one is hammer work at Building mastery 2 and gives 5 red, 5 green and 5 blue tech points. Taking a finished table down gives back about half.
- Its extension spots take the Alchemy Tools, which the game never lets you build (see Alchemy Tools I).
