Herbalism

Herbalism is a skill for gathering and preserving herbs, flowers, mushrooms, tree bark, fruits, vegetables -- virtually anything that grows in the ground or on a cave wall is covered under use of this skill. Herbalism also covers the knowledge of how to use these ingredients to prepare salves, unguents, tinctures, and even quasimagical potions. It has a "sister skill" in Alchemy, though the latter is generally used to handle more refined and less naturalistic ingredients.

As a Profession
As an herbalist, you can make money as if you were practicing a craft. In a given week (during which you must ply your trade for at least 70% of the days for 1/3 of the day [5 out of 7 days, 8 out of 24 hours for Earth]), you may earn half your check result in gp.

Gathering Herbs
If you spend four hours in a wild, natural area, you may gather half your check result in gp worth of raw materials. These materials are non-specific, and are used to create basic herbal preparations. If a given herbal recipe calls for a specific kind of herb, then that herb can only be gathered at the DM's discretion.

Horticulture
Herbalists may also prepare and keep gardens. An herbalist may keep a 10'x10' garden with one hour of work a day; each 10' square beyond that adds another daily hour's worth of work. Once per week, the herbalist may gather his check result in gp worth of materials from his garden. For each additional 10' square beyond the first, the herbalist gains a +2 bonus to this check.

Herbalists may opt to raise specific herbs. If the herb is native to the herbalist's climate, then no check is needed to do this. If the herb comes from a different climate, then the herbalist must make an Herbalism check once per week or the herb dies. The DC of the check depends on how far removed the herb is from its home environment and the pains to which the herbalist has gone to create a comfortable environment for the herb. Details are up to the DM.

Crafting
The main use of the Herbalism skill is in preparing ointments, potions, and other such things. The check DC for a particular item depends on its complexity and the delicacy of the raw materials. The time it takes to create a particular item depends on its cost, its DC, and the results of the check.

To determine crafting success or failure, follow these steps:
 * 1) Take the market price of the item in question and convert to cp
 * 2) Gather one-third that price in raw materials
 * 3) Make an Herbalism check representing one day's work. If the check is successful, multiply the result of the check by the item's DC. The result is how many cp's worth of work you accomplished in that day. When the cp value of the work done exceeds the item's value, you have finished the item.

Failures and Retries
If you are attempting to raise an herb outside of its native environment and you fail on your check, the herb dies.

If you are attempting to craft an item and your check fails by four or less, you make no progress that day. If your check fails by five or more, you ruin your progress and have to start over. In addition, 1d4+5 x 10% of the raw materials are lost and you must pay them again.

Action
Does not apply. Checks are made by the day or week.

Synergy
Five or more ranks in Knowledge (nature) or Survival give you a +2 synergy bonus on Herbalism checks. Five or more ranks in Herbalism gives you a +2 synergy bonus on Alchemy checks and Heal checks.
