Dom

Dom can be found in Catacombs. Drop below gear puzzle and head right until you reach a big room with sand platforms leading up. There, in the upper left room you will find him in a cage. After being rescued he moves to Karthas and will trade equipment with you. If engaged in conversation he will ask you to bring back his Hammer. Upon doing so, a new option to craft equipment in exchange for materials will be available.

"Thanks for the help, friend! I'm Dom, the local blacksmith. I wish I could help you clear out these corridors, but I'm better at making swords than wielding them. Stop by my shop in Karthas sometime. ''I will give you a nice deal on some new equipment!"

"Well, friend, are you up for a mission? I have some equipment up for sale, but I can't create anything new. Those creatures took my forging Hammer when they raided the town. It was given to me by my father when I began smithing, and I promised to always use it. Once my Hammer has been recovered, I can craft new items from raw materials you find. ''Keep your eyes open and let me know if you find it."

"Don't forget to keep an eye out for my Hammer! I'll need it to craft new equipment."

"Well, stoke my furnace, you found it! Ever since I lost my Hammer, I've felt like a scabbard without a sword. Now that I have it, I can craft new items for you. Just let me know which designs you're interested in"

"It's good to see you again! Take a look at my inventory, you may see something you like. Just be careful - they're sharp!"
