As long as the hunter is alive and free, the alchemist has no reason to brew potions and risk being killed. They can simply stay safely at home and collect the trophies brought by the hunter. Then, they can process them all at once. But if the hunter is in a cage, then yes, the alchemist has no reason to stay put. Does this option work for you?
