OK, I've sped things up so I can see what to do. I've mistaken myself, the sleeping potion also kills them, and you get way more xp for just brawling them in. I don't know why it wont work for you, but I put the tainted demon's blood, virulent agent and bonding agent in the lab and as soon as I put in the last part the sleeping poison was created. I think I know the deal. Did you tell Riki that you found an alchemist lab? Sounds small, but weirder things have happened.
