Details
Talk to Morris Jurinov in Asheran.
Description
If you are ever in Asheran, and you need a weapon, you should talk to Morris Jurinov... Morris the Blade... Morris the Arrow-Dodger.
As hard as Argon's hammer, and as curved as a farmer's sickle - apparently it's impossible to kill the man.
He can get you what you need.
Completion
If it doesn't work, you could always hit them with it.
