All crafting and artisanry using this skill follows the typical Tradecraft Practices (including Specialization). Craftwork uses some form of Utility (tool, kit, workstation) to fabricate items.
This craft uses common principles of Consumables Crafting.
Frame of Reference: All Skills are bound by the character's Setting (physics), and the details that their culture/society's Science (gathered by Technology), direct experience, and/or collective Records are capable of revealing. A character may not be able to apply their full measure on a different world, with different species and tools.
Each specialty has its own specific set of materials and tools. Some are shared with other related specialties, but the exact Utility Set is unique.
