Clan carcasses are a controlled resource.
Charcuterie needs to be more carefully governed than other professions; the clan’s animal carcasses often need to be butchered with high level skills in order for Cooks to have the ingredients they need. If you want to level Charcuterie using clan carcasses, please coordinate with Max or Liandra.
You are, of course, always free to level your skills using materials you gathered.
