I'm now 0/15 on this NM, 3 times with a TH 4 but most of the time solo. I usually had about 200mp left, and don't be worried about using avatar's favor if you can get down to a free fenrir (it will definitely save you more mp than the small amount of damage lost). Time your siphons if you need to as well, i'd usually pull out spirit and switch to siphon gear and let it fight until it does using day/weather relic to reduce cost.
I'm really disgusted with these droprates. Anyone who gets the item within 1-3 attempts of killing their NM should count themselves very lucky.

This is how bad my drop rates have been with these new NM's. Be warned that you may be in for the long haul if you camp these.
