PoE Storm Brand, Chaining, Mapping builds

I guess this is not very original but ever since i started playing POE I really liked Strom Brand. This league was the fist where I managed to get to t16 Map and make some amount of curreny. But I got stuck on one build using Hexblast. I saw a crafting video on YT - someone crafting an insane 7L SB Helmet, so i thought i wanted to make my own build based around that Item. I know this will be VERY EXPENSIVE if even possible, so that is what I want to find out. Please let me know if you think this would be possible to pull off. Also let me know about any suggestions about changes I

Been trying to build a Storm Brand Raider for HCSSF because of the following synergies: - Onslaught gives MS and damage - Frenzy Charges double dip with More Damage and Cast Speed - Easy acces to Spell Suppression & Elemental Ailment Avoidance - Can path through Armour and Evasion nodes on my way to the Brand Nodes - Can path to a lot of Mana Reservation Efficiency However I seem to hit a ceiling in both damage and survivability. Especially Damage. I'm looking for a secondary skill that could boost single target, but I don't see it. Tried Lightning Spire

I dropped said Body Armour early into the league and got very lucky 6-linking it. For those who don't know, it's the Heist Unique that lets you freeze with all damage at a higher effectiveness. Now what I'm trying to do is combining the strong freezes with high damage rolls of lightning skills and because I love the skill I'm going with Arc for the moment. Here's the PoB of my SSF Templar: While the plan to instafreeze Sanctum Guardians up to T16 map bosses works really well there are some roadblocks that are hard to overcome, na

Since the other dude is asking for more PoB, here is a tentative Lightning Conduit Elementalist. I looked at the other lightning conduit PoB and found it extremely lacking. Insane custom multiplier from everywhere, a shock calculated on the basis you have already a 100% shock on the target which it obviously won't, a need to alternate between lightning arrow and lightning conduit, an idea that using voltaxic make the build reach "a much high ceiling" while you are basically giving up weapons and ends up with a spell doing 40% lightning 60% chaos (very fun to scale the resists after that), etc
