To those who may have rightly freaked out about the skirmish weapons ( I say may have since by my own point not much is known about skirmish):

Considering how rare the visage pieces are it requires quite an incredible amount of luck and effort to obtain an entire visage set to enter Skirmish areas. On top of that augments are not static so many repeated attempts at skirmish might be called for to obtain multiples of the Augment item required.
