So I am a huge fan of the spell Goodberry because it removes the annoying need for players to worry about nourishment. I know I could just remove nourishment it from the game as the DM and not worry about that mechanic, but it is kind of a nice day to day management the characters have to remember to survive in the wild.

But the spell is fairly limited to only 2 classes, so I thought of making an uncommon magic item that my players could come across. So here is the idea Druids Bag of Berries: 

Druids Bag of Berries

This bag is a small deep green bag that has brown tree roots stitched into it that spawn from the bottom and wrap all the way up to the top sealing the bag shut. Every dawn stitches turn into real small roots and if the wearer reaches into the bag it will open. Upon reaching into the bag the wearer can pull out  berries.

These berries are infused with magic from nature and eating one works, in the same way, a berry from the spell Goodberry works.

Once you pull out the berries from the bag, the stitches return to actual stitches and seal the bag shut again until dawn.

I’d say the most value of this comes from not having to burn a first Level Spell every day, maybe have them buy it from a high level Mage, have him sell it as a “must have adventuring item” and have it be an optional upgrade rather than finding it in the wild or at random & feeling like a “shortcut” hope this helps
