Increase your Intelligence or Wisdom score by +1.

Instinctive Naturalist. You can add your Wisdom modifier when you perform an Intelligence (Nature) and Intelligence (Investigation) checks made to know or discover something about plants.

Providence of Nature. You can spend 10 minutes to search for ingredients to make a potion for which you have the recipe.  You already know the recipe for a healing potion and a potion with the effects of a Lesser Restoration spell. The potions created with this feature expire after 24 hours. Roll a Wisdom (Survival) check.  On a 10 or higher, you find sufficient potion ingredients for 1 potion.  On a 15 or higher, you find sufficient potion ingredients for 2 potions, but these must both be the same potion.  In places where plant life is particularly abundant, or if you are a Ranger in your favored terrain, you can make this check at advantage.  This feature must be completed as part of a Short or Long Rest.
