I think the first charm should be around Vex-5ist. Other than life, they are about mid-rolls meaning there are probably many sellers. It's a nice self-usable GC tho. Can be used on any DPS builds.
2nd charm is 1 life off perfect so I am quite positive that it will be a couple of HRs. however, this AR+Life GC isn't exactly popular in demand, more for a niche market. So, it will take some time
