This was copied from a post elsewhere on this site (didn't copy name of author): Used for a Druid Breast Plate Quest in Jaggedpine Forest...
In short...
Talk to Nolan Greenwood in Jaggedpind Forrest (you need decent faction to start this off by the way). He will ask you for a silver griffon feather and a Jade Studded Rawhide Tunic.
The Silver Griffon in NK will provide you with the feather. Its a level 40 Shadow Knight that certainly liked to HT my druid... doesn't appear to like snares either as its invulnerable to speed changes, but certainly not hard to kill at level 51.
Now start to cry... as the next part will take a while...
The Jade Studded Tunic is the result of talking to <first name> Wyndrunner (I'll edit his first name later if I can remember it). He will provide you with the tunic in exchange for the above listed Pouch of Polished Jade Stones from Greshvoul and a Black Rawhide Tunic.
Ok.. Lastly... the Black Rawhide Tunic. This is manufactured with the tailoring skill by a high level tailor. You will need:
1x Flawless Panther Hide, (from Elishia Blackheart possibly other named) 1x Dew of the Hatchling, (Forage in JPF - NoDrop) 1x Jaggedpine Sap, (Forage in JPF - NoDrop) 1x Wisp of Potemeid Hair (From Potemeids oddly enough)
Combine the Panther Hide, Dew of the Hatchling and Jaggedpine Sap to make a Cured Panther Hide. Combine The Wisp of Potemeid Hair and the Cured Panther Hide to finally produce your Black Rawhide Tunic. (/cry when the combine fails ;-)
Assuming you've made the tunic and got the above gems... Go see Mr Wyndrunner and hand in the Black Rawhide Tunic and the Polished Jade Stones. You receive a Jade Studded Rawhide Tunic.
Then finally off to JPF to get your nice new Breastplate from Nolan Greenwood by handing in the Silver Griffon Feathers and a Jade Studded Rawhide Tunic.
It is used in a Druid Quest for an item variously called breasplate chestplate and or tunic of the pine. see item lookup for Pouch of Polished Jade Stones also on this sie for details and discussion
