Angry Oak Spirit

Angry Oak Spirits are elemental spirits spawned in response to adventurers chopping down a Crystalsong Oak in Crystalsong Forest. They emerged from the dying tree to take revenge on the person that killed it.

As the quest Jack Me Some Lumber was removed in Patch 3.2.0, the trees and their spirits no longer spawn.
