PoE saldagmac builds

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
