PoE Witch Ascendancy, Orb builds without Mageblood

I just wanted to post about my build idea and tested since I think its really cool. I've tested Hydrosphere with spell echo and can confirm that the final repeat does have a 100% crit chance and when using it with greater spell echo it also inherits the extra aoe and more damage multiplier.

I stacked cast speed to make the build be able to clear maps a bit more smoothly but its strength is definitely in bossing. I defensive laye

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.
