Reins of the Bone-White Primal Raptor

The Reins of the Bone-White Primal Raptor is a raptor mount gained from Ku'ma the troll on the Isle of Giants. As a primal raptor, it resembles devilsaurs as much as normal raptors. Despite this, it bears a heavy resemblance to the obsolete Whistle of the Ivory Raptor, having the same white skin and violet eyes, but with a dark-purple underbelly and stripes, opposed to the Ivory Raptor's black stripes.
