Hylas

General
Hylas 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".

Also, for a fee of 10 gold he can customize a weapon for you, which will increase its damage by 20%, but means that no other character except the one it is customized for can use that weapon.

Location
Hylas can be found in Yak's Bend.
