Duncan

Found in cage on the first floor of Mines. To reach him you need Spiked Gloves. When resqued, he moves to Karthas where you are able to buy and sell ingots and gems. Starting a conversation begins his sidequest where he asks you to find 3 secret stashes and gives you his Shovel. Completing his quest rewards you with 500 gold.

"Thanks! I was getting bored sitting in that cage. I'm Duncan, one of the miners here. The only thing I love more than diggin' up minerals is processing them. I'm going to head back up to karthas and get the stamper running again. ''Come see me if you ever want to buy or sell minerals."

"I love Karthas, but the one downside of living here is that there isn't a band in town. So, for years, I have been burying my money down in the Mines, Probably not the smartest move since it's swarming with monsters now. It's too dangerous for me to go back in, but maybe you could get my money for me? If you bring back all three of my stashes, I'll compensate you for your time. Please, take my Shovel with you. You'll need it to dig them up."

"Were you able to find my stashes? Don't forget there are three of them!"

"Thank you for retrieving my money! I think it's time I found a hiding place that's closer to home. As promised, here is your cut. And you can also keep my Shovel for your troubles."

"Most people don't appreciate the beauty of minerals. Would you like to have a look at my collection?"
