Inquisitive build reaching 30 something imbue dice. 6 arty levels for +1 dice, rune arm for dread set gearing, and 6 ap saved from harper tree.
The dino rune arm is amazing with the skeleton raid optional 3% doubleshot augment. A 2d6 profane sneak dice augment, and it can augment the Fire Attuned proc. Its own rune arm damage proc scales at 200% RP. Just such a sick item.
