===Reagents===
Reagents are the central portion of this rebuild, in fact extreme emphasis has been put on them, as each reagent dictates the abilities granted to a Potion. Every Reagent has a specified use in Alchemy, and the effects of reagents are totaled up to determine the effects of the Resulting Potion or Poison. The Myriad of additional reagents necessitates additional world building elements, but rather than forcing a DM to specify that players see different reagents growing in their natural environment, Environments are a listed quality to Reagents. When within those environments a single check (Typically either Alchemy or Perception, whichever is Higher) is made to determine whether or not a player finds anything, and subsequently the quantity of what they discover.
While it adds to the immense complexity to have to take into account specific quantities of reagents, and is technically possible to use the "Spell Component Pouch" method of having reagent access, giving players access to every reagent at any given moment nullifies the Rarity ratings, and can heavily upset the balance of the system in its current state.
Every reagent has a set Value and Rarity, and these determine a few factors about the reagents, their availability is determined by their listed environment. The listed price can go up or down according to DM belief regarding the environment, a common reagent may be in surplus in an area that its native to, becoming cheaper as a result, but intensely rare elsewhere, fetching a higher price due to this.
