PoE 3.19 Kalandra Juggernaut, Chaos builds

Storm Brand HoA Jugg is my favourite build in PoE. I have seen some players in both SC and HC trade make this build work every league but they are not SSF friendly at all. I have been trying to make it work in SSF for a couple of leagues and I think I have found a version that I am happy to share in this subreddit. This build does not have a ton of dmg but the uptime is fantastic and the tankiness is through the roof. A downside to some people is that this build requires you to do heist to get some important items and uniques that help the build a ton but they are not mandatory for early progr

Just looking for some suggestions/improvements on the tree, and what aura's I should run. And what skills I can level with that won't require much (if any) regrets. For gear I have an idea of what I want, and don't really want to build it around any uniques since I play SSF/SSFHC exclusively. But with pretty terrible gear I'm already at 600k DPS, and I can sustain the damage as early as level 68-70 (according to skill self-damage), since my life regen should cover the damage taken.
