Yeah I was wondering what release sets they are or what ever they may be called. Also I'm trying to get two Icefangs if you know anybody.
It's referring to the latest released legends. In this chase the Planar Disturbances expansion. Icefang is currently the hardest non-limited rune to get a hold of. You can get it from the marketplace with $$ and luck. Or trading, but that is gonna be hard. Good luck with it though.
when the midterm comes out, it just adds the new legendary runes to the existing expansion, in this case planar disturbances. i also found this confusing at first
