I ran into this NM. I decided to give it a shot because I read it could be soloed by a 75 BLM.
I went to pull it with Gravity and linked two other bombs. I pulled them all together and slept them, then I kited Snow Maiden away and started nuking. My first spell did 900 damage and moved its HP bar about 5% <,< Fortunately, it sleeps easily. I just nuked myself down to low MP, Sleep 2ed it, rested to half MP, and repeated. I found Thunder does the best damage. I'd heard most Snolls were weak to ice the same way Bombs are weak to fire, but that doesn't seem to be the case with this NM. Bliz 4 does 916 and Thunder 4 does 1041, and I'm using Hyorin Obi with 1 Ice Weather. Fire does the high 800s. Watch out for deagro + regen. She seems to like to do that.
Anyway, no drop. 91 xp solo with band as a 75 BLM. That puts its base xp at 61.
