Hey man, good job on the 125. Taking a look at your gear…
So regarding an amulet, even finding an ancient with something like 9% CHC / 90% CHD / 15% Cold would give you a little bit more damage than you have now (you’d drop about 7% dmg from Str, CHC, and CHD, but gain about 11% damage from the cold%). So keep your eyes open.
Also, it’s too late now, but you shouldn’t generally have AS on your Azurewrath. It doesn’t actually help you in terms of breakpoints, and adds no damage in your current setup.
An ideal AZ will have Cold%-CDR-LPH or Cold%-CDR-AD. Or, if you can’t make it to the 47% CDR breakpoint (if playing CoE variant, which you aren’t) based on other rolls on your gear, and so only need to hit the 29% breakpoint, it could have Cold%-AD-LPH. Anyway, like I said, it’s too late now, but that’s still a solid weapon.
Not much else with an obvious upgrade available. But, with your paragon and Augments, I’m pretty sure you’ve got a few more GRs in the tank. 126 for sure, maybe 127 too.
