Treants are enormous enchanted beings whose bodies are born from the living trees of Kalimdor and Bloodmyst. They are tremendously strong and resilient to even the strongest blows. In times of great peril, they can be seen emerging from their shadowy forests to protect the land from evil corruption. Some, however, were tainted and corrupted by the Burning Legion ages ago. The corrupted Treants wish only to spread their corruption and hate for living things. Corrupted Treants are also found Bloodmyst Isle following the Burning Crusade expansion pack.

Treants can be summoned by Druids specializing in Balance magic.
