Gathering Reagents and Poisons
Gathering reagents and herbal poison components requires one of several checks. Profession (herbalist, hunter) or survival to gather the materials.
The DC is 15. Multiply the result by the DC to determine the gold pieces gathered per week of work. Divide the result by 7 for daily gp gathered and divide by 40 for hourly.
Extracting special reagents and venom requires one of several checks. First is a survival check to track a creature. Second is after it is dead it requires a Survival or Heal check to remove the reagents. Special reagents can be used as special power components in Item Creation. There are several checks required.
1st – The size of creature determines how many reagents are possible to extract; tiny 1, small 1d2, medium 1d4, large 2d4, + 1d4 per additional size category.
2nd – Roll the correct Knowledge Nature or Arcana check locate the reagent DC 10 + HD of creature, subtract 10 if the reagent is obvious, such as Basilisk eyes. Fail increases step 3's DC by 5. This can be done as a Full Round Action.
3rd – Roll a Survival or Heal check DC 14 + HD of creature to extract. On failed check, half the reagents rounded down are spoiled. This can be done within 5 minutes per HD of creature -1 minute per level of the extractor, to a minimum of 1 minute.
Each special reagent is worth enough gp for one potion or dose of poison. For example Basilisk eyes can each be turned into potions of stoneskin, stone salve, or ink for any "stone" based spell.
