A smaller "garden pot" style item that can accept all the types of herbs/mushrooms in game. You take clipping from them. The clippings can only be used as replacements for the ingredient in alchemy.
For pre-Silver early game the alchemy is a bit limited. It would be very neat if we could take the Herbal-Grind and boil them in a cauldron to remove a few of the properties. Make early game alchemy feel more witch inspired.
* Also if we got a 4th type of elixir that used the different types of alcohol as the base ingredient.
