===3. Working with and preserving herbal substances.===

Alchemists are instrumental in the preservation, treatment and distillation of various herbs, monster parts, etc., making them ready for further use, whether as a direct application (such as comfrey) or as an ingredient for something (monster parts for magical items, for instance).  Doing so requires a base throw of 18+ and a day of time for a given quantity.  Modifiers may be applied as follows:

*For every additional 500 gp in value of the lab she gains a +1 bonus to the throw.
*Possessing a library worth 2000 gp adds a +1 bonus to the throw.  A successful throw indicates the value of the library is increased by 50 gp, due to the notes she has taken during the process.  
*For every additional 1000 gp of worth of the library add +1 to the throw.
*For every additional day spent add +1 to the throw, for a maximum bonus of +5.
*For every additional 50 gp worth in materials and consumable materials add +1 to the throw.
*Note that uncommon or rare items will likely have a higher throw.
*Characters that have selected the Alchemy Proficiency twice gain a +4 bonus; those who have selected it thrice gain a total +8 modifier.
 
A throw of 1 always fails.  There is a 50% chance that the substance is destroyed or, in the case of herbal tinctures, spoiled and made poisonous.  The alchemist is not aware that it failed in these cases.
