Arthur Ayala

General
The anonymous "Crafter" is a Weapon Crafter (weaponsmith).

If you deliver him the required input amount of crafting materials and pay him a fee in gold he will craft you one of the weapons from his "menu".

Unlike all other Weapon Crafters he can not customize weapons. He leaves this to Elias, who stands right next to him.

Location
Crafter can be found in Ascalon City (Pre-Searing), right next to Elias.
