Crystal Arms and Weapons

[Lys]

So the Crystal Arm blood charm grants you an extra unarmed attack at the cost of 1 strain and -2 to all Action Tests that round, including the attack itself. I'm wondering, what happens if the arm is holding a weapon? The charm description states that crystal arms are just as capable of grasping and manipulating objects as normal arms, so clearly they can hold weapons, but can they use them with their extra attack? If they can use them, would they be rolling Unarmed Combat or Melee Weapons?

A strict interpretation would be no*. I take this to mean that if the arm is not actively holding something, you can take strain to make it move faster (grant the extra attack in that round).

*The 'exception' being "attached weapons" which use the Unarmed skill/talent.
