Trio Setting Tool  

All you need to do is buy a solo setting tool. Just 1 will work. Put it in your jewler's kit n hit combine. That gives you the duo setting tool. Repeat the process 1 more time and you get your trio setting tool. I bought my solo setting tool in th plain of tranquility from npc Taliz (thats the last name of npc) This npc is located in the building north of the pok book zone in/out. Sema building as the bankers are in. loc 885.40, -1750.61, -892.54
