Your time in the wild has made you adept at finding cheap, natural substitutes for spell components that would be impossible to find outside of civilized society.
Prerequisite(s) Eschew Materials.
Benefit(s): Once per day, you can attempt a Profession (herbalist) or Survival check to use herbal substitutes for the required material components of a single spell that normally cost up to 25 gp (DC = 5 + the gp value of component). These components can be used only for your own spells and can't be sold. They decay within a week if not used.
Normal: You must buy spell components for any spell requiring a material component.
