The tree spirit is a monster similar to the tree spirit random event, however the combat level and loot is far different from the random event version. It may be found in the Enchanted Valley, along with other former random event monsters, by cutting down any tree in the area. Players may reach the Enchanted Valley by using the fairy ring code BKQ.
Before the Enchanted Valley was updated to host the former random event monsters, the combat level of the player would affect the combat level of the tree spirit (the higher the combat level of the player, the higher the level of the Tree Spirit with a max of combat 154).
Tree spirits will continue to appear as long as you continue to cut the tree, however, you will eventually stop cutting the tree with the message "You can't chop down a tree while you are under attack." Several tree spirits may spawn before you get this message despite being under attack from all of them.
