There are six levels of essential compound extracts each with different levels of requirements.
Attributes are explained more in chemistry. Each time a chemistry lab is successfully used to make any essential compound extract, all requirements for all types of extracts are redetermined. For the simplest level, Geb, two attributes are randomly chosen, and set to -2 or +2. For a compound to match, it must have a value greater than +2 or less than -2 for both attributes at the same time. The requirements for the other five types follow the same pattern.
