Just so ya'll know... you cant compare NM's to normal EXP mobs.
Never expect to be able to solo an NM unless your 15-20 levels above it.
In a full PT you want to be at least the same level as the NM or maybe 2-3 below it if your really good.
Don't try this NM in a PT less then LV60, NM's hit harder and have more defense and HP then normal mobs.
Ive heard a Ranger with Sleep Arrows can solo this thing at LV71 but it takes about 30 mins of steady shooting (naturally the sleep arrows keep putting the NM to sleep so you never get hit).
