Looking to make a pair of Greensteel Kama's for my monk, however, I can't decide on which upgrades to take there are some really good ones out there. Looking at one combo for Holy 2d6, with Acid Burst and Acid Blast so it gets Transmuting/Bleeding/Keen. Or even taking 3 different elements for elemental mastery. Any thoughts on some good upgrades to apply to it.
