Oak

The oak tree could be found in various places in Faerûn.

Abilities
Some oak trees that were large and 50 years of age or older were known to have a mystical ability to form their powerful auras into animate shapes, which typically took the form of a dryad.

Chime
Chime oaks were specific to the northern sections of the east starwood, a portion of the forest of Cormanthor. They were like regular oaks, but appeared as though they were made of glass. Their leaves froze easily in autumn and winter, and did not fall off the tree, instead making a tinkling noise in the wind, which gave the tree its name. This noise attracted basilisks.

Marsh oak grew in the Farsea Marshes and gall oak and black oak grew in the Vast Swamp.

Uses
Oak wood was used for crafting countless items, such as strong doors and tables.

Locations
Oaks grew in the starwood area of the forest of Cormanthor, where they could grow up to 400 feet (122 meters) tall. They were also found in the Reaching Woods in west Faerûn. Gnarled oaks grew around the fringe of the Vast Swamp.

Notable Oaks
The Sacred Oak was a highly respected ancient oak tree in Leuthilspar on the island of Evermeet. The wood and wild elves believed that it was the first tree on Evermeet, while it was more generally believed that the tree came from Arvandor.

A huge oak tree formed each of the four corners of the Elfstone Tavern in Waterdeep.
