Naturecraft [Nature]

Requires Monsterbane, Natural Defiance or Metallurgist Feats

You can use the tools of an herbalist for a variety of purposes. By
using 5 gp’s worth of common herbalist’s supplies and spending
at least 8 hours aquiring, preparing, and packing them into a kit,
you can create an herbalism kit from scratch.
In addition to the other benefits an herbalism kit provides, you
can spend 10 minutes to produce one of the following effects:
• You can purify a portion of food or drink, rendering it free of
poison and disease.
• You can increase the potency of a healing potion for 1 hour.
When you do so, the potion restores the maximum number
of hit points instead of rolling.
• You can create up to 1 vial’s worth of acid, sealing wax, or
perfume.
