If you are skilled you can take this guy down in about 25-45 mins without much trouble.
Solo'd him as 75 RDM/BST
I suggest using disposable pet jobs and take a whack at it...
Hits for about 300-500 without buffs... 100~ with buffs and Earth Staff
Ran back and forth between Knight Crawlers area, Rumble Crawlers, and Dragonfly area using them as pets. kept buffs up and stayed far away as possible from the it. Some of ur best pets would be Flies and Crawler Hunters.
Both items dropped.
Good luck people.
