The Hunter's Charm is the start of a Hunter quest chain.
The quest is offered by the hunter trainers in all major capital cities as of patch 2.4Ogtinc is literally on top of the cliffs above The Shattered Strand [42, 43], just northeast from the Ruins of Eldarath.
This is a hunter-only quest.
Ogtinc of Azshara has sent out a call for seasoned hunters such as yourself. He is a furbolg hunter who has left his tribe to aid the Cenarion Circle. His teachings are meant to enrich the wisdom of others who share his craft, and guide them toward maintaining a balance. You would do well to speak with him.
Ogtinc resides atop the cliffs of Azshara, northeast from the Ruins of Eldarath.
It is no longer my purpose to hunt, but to teach the hunter. That is what fate has handed to me.
Craft with me a hunter's charm -- a collection of trophies from fallen prey that will remind you of your past trials and triumphs. In the end I will keep the charm, but reward you with something else.
- Patch 1.7.0 (13-Sep-2005): Added.
