Bolereh is a weaponsmith in Camp Hojanu. If you give her the required amount of crafting materials, and pay her a fee in gold, she will craft you one of the weapons from her "menu". Also, for a fee of 10 gold she can customize a weapon for you. This will increase its damage by 20%, but means that no character other than the one it is customized for (or that character's heroes) can use that weapon.
