PoE Witch, League Starter, Critical, Mapping builds

Yo fellas, lets talk about Cold BV and using the new Ring Anathema. I leaguestarted right away with this Build as I saw the last line on the "Asphyxia's Wrath" Quiver and "Anathema" the new Curse Ring which sets your Curse Limit at your Maximum Power Charges. The last line says "Hexes transfer to all enemies in a range of 30 when hexed enemies dies". Since most Cold BV builds already playing with this Quiver and have a lot of Power Charges, this would be the perfect Playground. Cold BV of course abuses Explosions in every possible way (Occultist, Herald of Ice, Herald of Ash, Explosion Ches

Hey guys, recently thought about possible offmeta league starters and came up with this Chaos BV, heavily inspired by the trending Cold BV variants. Build has 60% chance to explode ennemies and gull+blunderbore for fast mapping, as well as badge of the brotherhood for high withering step uptime to have it up for almost every pack and get the wither damage multiplicator for the explosions too. The build has actually 3.5M dps with the current config even against sirus which seems pretty decent. Ive found two things a bit worrysome:

Looking for suggestions on an Occultist Cold-BV league starter. Budget: low (Mostly spending for 2 strong prefixes on staff) If you've got suggestions on where to take it for min-maxing, that would also be great; I'm coming back after a couple of leagues so I'm \rusty\ - should I go powercharges with 2x Void Battery? Something else? etc - I expect I'll want to respec eventually once I can craft/purchase decent cluster jewels, but don't want to assume I'll be getting them pre-red maps. If anyone has a better-looking PoB using Elementalist instead of Occultist, I'm all ears, I'd just prefer
