The helpfile for Fortitude of the Rhino states that vuln-blunt races are prohibited from taking it... specifically "Shapeshifters who are naturally vulnerable to blunt damage may not choose this edge. "

Yet I was able to take this on my gnome shifter Gianath, and it appears in my edge list.

Does that mean I wasted an edge and it's worthless to me? Or was the helpfile wrong and it is supposed to be available to anybody?
