This is a random drop in the Hinterlands. It has been reported to drop from Vicious Owlbeasts 3.5% of the time, and about 0.5% of the time from the following:


 * Saltwater Snapjaw
 * Green Sludge, Jade Ooze
 * Mangy Silvermane, Silvermane Wolf
 * Witherbark Scalper
 * Vilebranch Scalpers, Soothsayers, and Aman'zasi Guards

As with many items that start quests, the drop rate may be somewhat higher than reported. Once you have completed the associated quest, it won't drop for you again, and so is not accurately represented in collected statistics.
