PoE Bright-Preference-81, Cold builds

I started playing poe quite a while ago. My first few chars didn't get past acts. The first char that I really brought to end game was a frost blades champion way back in bestiary league. With the new stuff we've seen these past leagues, I think the skill plays quite differently than how it did before, and I do too. I'd like to try out the new amulet + loreweave interaction, if it isn't too expensive. End game, I'd like to see if the new ring will be as OP as it sounds. Even if it isn't, I'll still have a fallback as I've never played eternity shroud + heatshiver which should be great. Howev
