Berries are a food item that restore 2 ( 2 ) a piece, making them a rather ineffective food. However, they can be used as a decorative item on plates; for example; at your Hobbit picnic table or using the bushes to decorate your orchard or garden. In addition, as of Public Beta 22, these can be crafted into a pie and an assortment of drinks. As of Public Beta 29 there are also poisonous wildberries.

There are 6 different varieties: Raspberries, blueberries, blackberries, cranberries, elderberries, and wildberries. They can all be harvested from their respective bushes, giving around 2-5 berries and leaving a bare bush. Once the bush is bare, the berries can be re-grown using bonemeal, or by being left to grow back after a period of time. Read the article on the bushes for more information.

In everyday language, a berry is a small, pulpy and often edible fruit. Berries are usually juicy, rounded, brightly colored, sweet or sour, and do not have a stone or pit, although many pips or seeds may be present.

If you are living off of berries in the wilderness, be careful what you eat! Wildberries restore hunger, but also deal a few seconds of mild poison. They are not completely useless, however - this poison can be extracted into a bottle of poison, making them a very useful crop. They could, in fact, be considered the most useful berry for someone on a server who doesn't have many hired units, as not only can they be made into a delicious berry pie, they can be used to assassinate one's enemies.

Sometimes, NPCs such as Rangers of the North will eat berries to heal themselves after combat.
