has the full list of weapons you can make in Dwarven Town. I never really waste too much time with Mithril because my Force is usually strong enough at this point in the game but if you want to get in Dwarven Town make sure you use the Dry Stone at the river's edge where the dents are, and the oddly colored forest on the other side.
