Elixir of Numbing

Description
Brewing elixirs is a dangerous, often fatal pursuit. The wrong combination of ingredients is poisonous, or worse. The larger problem, however, is that apothecaries are loathe to share their secrets with one another, for fear of losing their business advantage. Which means that each and every practitioner has their own specific set of recipes for creating a desired effect.

This elixir is often given to slaves to numb their senses to the heavy loads that their masters pile upon them.
