PoE Arcanist Brand, Hierophant, Minion builds

Could I have some advice on what I should be working towards now as cold SWT? I'm mostly doing sanctums at the moment so damage is more important than survivability, but I wouldn't mind cheap upgrades for that either. I am working on a +2 wand following the crafting AMA that was posted here, but wanted to make sure there was not another easy upgrade before I continue spending all my currency on it. Pob:

So I was thinking about what spells would benefit from the Brand Recall tech that was brought forth by a random redditor. Overall, with \~1s brand recall and 7 brands, it's equivalent of casting a spell an additional 7 times a second, but spells are triggered on top of you, have less aoe, proj range and fire in random directions(tested this briefly, not sure). Most spells would be very clunky to use, we need specific proprieties: Triggerable by Arcanist Brand. Benefit from pseudo cast speed/burst. Good coverage despite drawbacks. Something like Eye of Winter, Arc or Forbidden Rite woul
