I have all the required items/skills to do it: potion creation guide, mixing bowl, empty test tube, morning dew of yggdrasil, seed of life, pharmacy at lvl 10 and bioethics learned. Yet when I use the pharmacy skill, I get the "You can't create items yet." error as if I didn't have the required items. What am I missing? Am I supposed to do a quest or something? Is this a glitch? I attached a photo showing my inventory and skill tree.
UPDATE: Please disregard, I figured out my problem. There is a difference between "empty test tube" and "glass tube". Once I got some glass tubes, I was able to make embryos.
