PoE 3.23 Affliction Hardcore, Cold builds

Hello, Looking for help with Vortex in SSFHC. Go easy on me this is my first self-made build. I primarily play SSFHC, and I'd like to make my own build from scratch this time. Most of my characters have died so far, and I'm hoping this one will be safer with chill/freeze effects. Gear equipped is just crap random gear I have on one of my leveling toons. Using Vortex with Grace, Determination, Tempest Shield, and D,Banner. Thanks for looking, and I appreciate your help!

PoB: Pretty late in the league so this probably won't get much traction, but I wanted to post this anyways as this is one of the most fun builds I've ever played. I won't claim there's anything super unique here as the core is just a pretty bog-standard power charge stacker, but I am surprised at how relatively underused CSoP is cause this thing hits like a truck (albeit a smaller truck than Penance Brand I guess lol). Pros and cons first and then I'll go into a little more detail about some interesting aspects. Pros \- Insane
