|“||[Treebeard] went to the back of the bay, and then they saw that several tall stone jars stood there, with heavy lids. He removed one of the lids, and dipped in a great ladle, and with it filled three bowls, one very large bowl, and two smaller ones.||”|

Ent Jars are special blocks that are used for making Ent-draughts, the revitalizing drinks of the Tree-herds.
Ent jars can be found spawning randomly and exclusively in the Fangorn forest, making them almost impossible for evil players to find unless they are incredibly well equipped.
Evil-aligned players beware: If you do not have a positive alignment with the Fangorn faction, then the Ent-draught will instead give you the Poison effect for a few seconds when consumed.
The Ent-draught can be collected by right-clicking the jars with a Vanilla bowl. Since the various Ent-draughts are quite useful, it is advisable for good-aligned players to take the time to find some of these jars; the pay-off is high.
Until the Public Beta 19 update, the jars would fill up gradually as it rained (see below). As of newer versions, they can now be filled by right-clicking them with a bucket of water. Once the jar is filled, the draught can then be made by right clicking on the jar with various plants and flowers that grow exclusively in Fangorn forest.
In the current version (35.3) empty Ent jars do not fill up with water if left out in the rain. This is a bug and will be fixed in the next version.
