Mow I see that the refined orangium is in this categorie as well so I only need these 5 but I already researched them but they aren't in the list of craftable items. Is this a bug or do I need somehing else to unlock them.
You dont need nothing else, they should be available after first vanpire quest, there you first feed her organium. Skill crystals also Just appear after research, i dont remember any quest / item about them. Ask Ryen (dev) himself, he should know about it
