Collect 5 Grishnath Orbs and 5 Dire Pinfeathers and then combine them into Exorcism Feathers. Use these feathers to exorcise and slay 5 Koi-Koi Spirits from the Raven's Wood Leafbeards. Once you've done this, return to Treebole in the Raven's Wood of the Blade's Edge Mountains.
5x Leafbeard Exorcised
The Grishna have caused the leafbeards and stonebarks to be inhabited by evil koi-koi spirits.
We must save the trees or soon all of the Raven's Wood will be lost forever!
Combine the magic of a Grishnath orb, found throughout Grishnath, with a dire pinfeather from a dire raven.
Use the resultant exorcism feather to draw out and slay the koi-koi spirit as quickly as possible. The stonebarks are too powerful for this ritual, but if enough leafbeards are saved, they will be freed as well.
