PoE Lightning, Bossing builds

Here Im showing my Theory build for a cast on death ignite version. If you ever seen that one quack build video. I wondered if u had any interest in pushing this PoB even further and probably lowering cost? I might use this as my personal "boss killer" especially if a lvl 70 can do the job. It could also give me ideas for my classic ignite discharge PoB. This PoB is Started off from my classic PoB : Farrul + Badge regular Discharge ignite elementalist. It might not be realistic so u may want to disable things if u consider them non legit for a Cast On Death. I went the non endurance

I'd like to put together a Cold Conversion Sweep character. Seen a few Sweep videos online (FastAF & Mathil) but want to do the gearing my own way. 1. putting Sweep in a pseudo 7/8 link helm similar to this one in the picture 2. 6 link totem setup in weapon (voidforge or crafted rare using Fleshripper/ Banishing Blade/ Exquisite Blade) 3. double curse setup in chest (Explode or Carcass Jack depending on ascendancy) or just get curses on rings and use this 6L for another setup What would be the ideal ascendancy to go with? Trying to decide between Assassin, Slayer, Berserker, or Raider.

600K Unbuffed Shaper DPs 1.3M Buffed Shaper DPS   Easy to start gearing with a high ceiling for OP gear late game.   Fun easy build that should be good for both clear and bossing without gem swapping. While also not being a 1 click mindless build.   Slap the enemy with consecrated path. If things get scary hit enduring cry. If an enemy is feeling a bit too tanky use intimidating cry.

Important notes Mana regen % anywhere you can get it from is really really good - start with clarity and replace it with herald of thunder once you get enough mana regen Gloves w/ spell damage leeched as ES are a huge survivability boost. Surgeons prefix on flasks is stupidly OP (we have 100% crit chance and fast cast speed so this is insanely good for us and gives the flasks massive uptime on bossfights)
