Glacial Hammer Self Chill Chieftain

Hi All. Preamble first...I'm fully aware I won't have the exact items in this build. I should be able to get a decent 3 mod watchers since I have a ton of auras, but I'm aware it 99.99% won't be exactly the one I have listed. I know I should swap the spiked gloves since eater/exarch overwrite, but I'm lazy so I just took off the melee phys. I've been playing a long time, and I just use my initial pob as a guide to what I'm looking for. Most of this shit should be rather cheap, with the most expensive stuff being the watchers (can even go budget on this) and the gems. I plan to grind out a mage blood this season as my goal (last season was kill all ubers).

So long preamble, but didn't want people to harp on stuff I'm currently aware of (yes this includes shit like flasks checked). Just really looking for any additional tips or tricks I may have missed (first self chill build I've played or made), something I'm not thinking of, or even just optimizing tree pathing. I do plan on using trauma support, though not sure which of the links drops off...pob can tell me later.

Thanks in advance for any suggestions!
