PoE Fire Trap, Trap and Mine Damage, Cold, Duration builds without Hexblast, Righteous Fire

PoB: Here's an idea for a league starter that I've been thinking about for a while. It converts the cold damage hit from Cold Snap into fire to ignite enemies while still dealing cold DoT and chilling, using increased cold and elemental damage and generic DoT multi to scale both DoTs. Normally I just flesh out a tree when theory crafting, but Mathil released a Wave of Conviction ignite starter build and I decided to plug my tree and skill into his gear, just changing the some of the fire modifiers to cold (which I imagine should be cheaper this league anyway)
