I will check them out thanks, and yea I already got the cold damage converted to pierce with the Helmet I use I think it is.
True, I always forget that you have a Belgo Blademaster :rolleyes:
I have a couple extras of each of those amulets (well not the FG one lol) and I can craft some bloodied crystals for you if you are interested
It isnt that rare, isnt it? 
I really like the set.
Sure I would love to take some bloodied crystals. How would we do that?
Yeah but I already have an infiltrator with that set so I did my blademaster a bit different and use Cadance as main attack skill.
Like all other trades. PM me your steam account and I add you as friend, we then meet in a multiplayer game that one of us create and then we trade items 
I have to check again exactly which of those amulets I have duplicates of.
