The iron dwarf brooch can be found on any dwarf monster in Northrend. I usually live in grizzly bear mountain, and there is a Danyag in the lower right corner of Onekwa camp. If you kill dwarves there, two or three will come out. Tea crystal and sun crystal are the lowest gems, which can be bought in auction houses or processed by themselves. After the assembly is completed, right-click the iron dwarf brooch to synthesize an evil day brooch. And daily life. I want a keel. I usually kill on the storm cliff, and now it's on the left side of the storm temple ~
