Skilled Herbalist

You've been taught how to craft healing remedies with a variety of herbs and plants. You gain the Alchemical Crafting feat, except you must select the following items to add to your formula book: Antidote (Lesser), Antiplague (Lesser), and Elixir of Life (Minor), as well as a fourth 1st-level common alchemical formula of your choice. You can use Nature to Craft an alchemical item that has the healing trait, rather than Crafting.
