I do not know what the Wind Sword is or what it is supposed to do in Gyphon Mtn.
What it does in HW would kind of depend on that but here are some ideas based on
the name:
- It has a built in Lashing Wind feat (5w). You can swing it at somebody out of
close combat range and it lashes them with tearing winds.
- It has a built-in Wind-Warrior feat (16). If you throw it into the air it will
fight by itself as though held by an invisible warrior.
- It has a built-in Wind Affinity (19) that can be used by the wielder or can
augment an existing wind affinity.
- etc etc.
This is all stuff that would have to be determined at creation.
So what does the Wind Sword do in Gryphon Mtn? What is it made of?
