This dropped in Heroic Mode Karragas kill for my guild on Thurs night. I lost the roll
Now looking at more closely, the color is indeed different than the one my guildie has it. His version is silver with green, red lining on the back and sides. It means there are two different color variations. Good to know ;3
This mount model drops from HM Soa and HM Karagga. The Soa version is red, the Karagga version is grey. They look pretty sweet. We imagine there must be a Nightmare Mode version that no one has seen yet.
