PoE Waaif, Cold builds

EDIT: There is a mistake in a title - It's 71m TOTAL DAMAGE from ignite, actual dps is 9m, really sorry for a misinformation Link (Endgame Setup) - I'm not even close to be an expert in build creation, just wanted to share my attempt at creating something of my own build (maybe as a starter). Any suggestions are welcome! Concept: Replica Nebulis (15-20)% increased Cold Damage per 1% Missing Cold Resistance, up to a maximum of 300%
