ok while doing Salvage in Bh. remenants on the first floor theres a NM that might pop called Big Bomb. you have to kill it without it self destructing. If you do thatt it pops a NPC that brings you to a secret area that has a NM that looks like it. DO NOT KILL IT!!!!!! it pops mobs that u must kill ( the annoying chigoes). after a whileit pops a mob called Dune Widow. after that dies it may drop these hands and i think 2 other items
