Seems to be the only NM that hasnt been popped yet. I'm going to go out on a limb and say it probably drops Skanda Boots (resist gravity trait makes sense dropping from a cluster NM). I spent a total of 16 hours this week killing Clusters all over Mount Z and nothing has popped. If it is a lotto I think it would probably pop in the Dahak area ( there are two bombs with the Dahak and another 5 in the tunnel on the way to the execution chamber). It seems too unlikely with all the people killing clusters near the gate for their BLU friends that nothing has popped there yet.
There's also a ??? above one of the metal lids near the Energetic Eruca pop area that doesnt seem to be used in a quest. It gives the message, "there is a detached part here..." or something along those lines. I've tried trading random cluster stuff to it but nothing seems to work.
Does anyone have any info on this thing? It's driving me nuts. Any sort of lead would be much appreciated, even if it's just info about what monsters are nearby in the dat files so I can narrow down my search.
