The All-Artisan's Guidebook

These books contain information on how to create useful items:
 * We all know scales of a dragon can be used to create life potions. But if you have 6 of them and a simple chain armor, it can also be used to create a special suit of dragon scale armor.


 * You can use a forge to merge a Ring of Archery with any bow. The bonus of the ring is then transferred to the bow.
 * I've taken one good look at the Spider Queen before I ran for my life. But I am pretty sure a good artisan can fit one of those fangs on a scimitar to create a poisonous blade.
