Hexapos was the last rare hunter creature I needed to uncover. It took me a while, as a lvl 86 in a lvl 90 zone without flying. He's got a huge patrol range and is the only white strider since Marticar, the rare Outland strider got a coat change.
You have to follow the tracks backwards, they're still bugged like all the other tracks!
