I know that the charms are dropped randomly so you'll just have to get luck. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
I know also a good ring and you can find him in the house with the portable bed. This house is close to the cursed abbey. Look for a key outside the house then look under the bed for a hatch, use the key and voila you have found a ring.
Also save before you open the hatch because if you get a ring that sucks, you can load the game and open the hatch again and see if you have a better ring then because items are randomly generated. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
