Harvest Parts

(General)
You can extract the choicest parts from a monster's carcass to use as resources when crafting items.
 

Prerequisites

Monster Harvesting 1 rank.
 

Benefit

When you use Monster Harvesting on a Dead creature, you can roll an additional harvesting check with a DC of 10 plus twice the monster’s CR (you still add any bonus from your Knowledge check to this roll). On a success, you gain additional resources from the creature that can be used as raw materials to Craft alchemical, masterwork, mundane, or magical items.
  The value of these raw materials is equal to the monster’s CR squared x 10gp (increases to CR derived from class levels do not contribute to this value). They cannot be bought or sold in most settlements, and typically have no value outside of their use as a raw crafting ingredient.
  Items crafted using these parts must be made of a suitable material (typically bone or hide). No more than half the raw material cost of an item can be supplied with harvested parts. Harvested parts remain usable for 2 days before they rot (unless used to Craft objects or somehow preserved).
