If I can find a reliable RDM/BLM, and a NIN/WAR, I can go as NIN/WAR myself. I have an Ambrosia ready to go to re-try Crustacean Conundrum.
The Mannequin Body can drop off of BC20 in Palborough Mines. I've tried twice now. First attempt, got one crab down, second attempt, got two crabs down, but our rdm was taken down and the other ninja and myself almost got the Heavy Metal Crab down, until it's blood weapon did us in.
If you have a NIN/WAR or RDM/BLM with *good* gear, I'm willing to try this. I spent 100k on gear last time, only to be disappointed big time. If you are decked out and willing to give it your all, then I will be willing to give it another go. I have head, (can reget hands, sold another pair for 200k), and will continue looking for body piece that doesn't cost 700k.
