Does Soul Vortex hurt your own units too?

bone armor is in my opinion best used for SC's especially if going up against hordes of chaff, then it's like having regeneration and reinvigoration at the same time.

i would advise you invest in an SC chassis, give it two frost brands(or fire brands if the enemy is cold resistant) and the bone armor, and get some buffs on him like luck and quickness. you should then be able to take out any number off chaff.
