PoE Frostbolt, Orb builds without Ice Nova, Ice Nova of Frostbolts

PoB: Tldr; The build uses MoM and mana as the main mechanics. Defenses include Petrified Blood, recoup and block. By stacking Megalomaniacs, the build achieves high mana regen. I tried to explain the mechanics used but the post isn't a complete so don't hesitate if you have any questions.
