Editing Arcane Background (section)

====Alchemist====
Introduced in the sourcebook "Smith & Robards", Alchemists are mad scientists who have turned their back on the typical mechanical sciences to instead focus on the chemical. Or alchemical, rather. These Mad Scientists focus on developing potions, ointments and elixirs (the preferred general term) that affect whatever they are poured onto or into in miraculous ways. They still receive inspiration from the manitou, and they still rely on Ghost Rock; the foundation of all alchemical elixirs is "Philosopher's Stone", a carefully heated dose of powdered Ghost Rock mixed with human blood.

Alchemy is more of a subsystem to Mad Science than a unique Arcane Background. Alchemists just take the Science: Alchemy Aptitude and the Mad Scientist Arcane Background, and they're done; no need for the Mad Science Aptitude, because Science: Alchemy is what they roll when devising a formula. This means you can easily branch out from conventional mad science to alchemy by taking the Aptitude at a later date.
