I soloed the NM as a lvl 56 NIN/SMN. waited till night for the EVA bonus, used a jackolantern, and a wind staff for the weapon.
I sneaked then hit the ??? pulled the BRD with carby, enfeebled, then nuked the hell out of it with ninjitsu. I should probably note that my ninjitsu is capped, this effects sticking your enfeebles, and I'm not sure but probably the dmg of the elemental spells as well (correct me if i'm wrong). Took about 10 mins to kill it. I used a vile elixer and vile elixer +1 two hyper potions and about 6 or 7 X-potions. It was reletively easy. Didn't bother to summon anything because a lvl 28 smn would probably not be very effective agains a lvl 55-57 NM. Believe it or not, with slow and blind and all the eva enhancement I only used 5 shihei the entire fight.
This is very easy, if I can do it anyone can lol.
