Gemstone of Emperor Bloodfin
-Random drop from Shadowmane Werewolves in Stoneroot Falls. They are hanging outside their cave in the back part of Stoneroot Falls. It took about 5 hours for 3 gems to drop.
Soloed elder shadowmane, got gem on 7th kill (kill roamer on the last bridge, then use pet pull to split there are 2 pack of 2 mobs, don't try to root/dot spirit, they gate, I gated barely twice because of that).
Doh
