Was pretty easy to do, I got EM pet and we fight it together, me and NIN did WS together for additional damage from skill chain, it has HP+100 pr 3 sec so hard to solo, you really need that extra damage it is around lvl 73-75 because we got 37 exp from kill.
Yes we BST do find the most strange NM lol I went there exploring Uleguerand Range found this one inside mountain only reached by sliding down the side from mountain top landing on a platform leading into cave.
