Might be that I've just been unlucky, but drop rate doesn't seem very good. Out of 3 kills (2 with Blue proc) we got zero Burattinaios, always got Aqua Belt and the Stoneskin one (and some Colorless Souls).
No TH though. Next time I'll make sure to bring a THF.
Oh and btw, I was very worried before fighting the VNM itself, but it turned out it's really easy. Range of the poison aura is 20yalms, not 25. Make sure to have a WHM healer, or if you don't then rely on Barwatera and Carol together to minimize the damage of spells. Tidal Wave especially can be dangerous, randomly does very high damage. Mostly casts Bloodpacts and -ga spells, his only single target ones are Flood II and Water V (not reported on Wiki list)
