unwilling soul is in a group of auto rifles that have really low impact, but maximum fire rate, with a big magazine size. They also have really poor stability. They can be fixed with the stability perk, but the unwilling soul from the vendor does not have the stabilty perk if i can remember rightly. There is one available with the perk, but its from a drop, not the vendor. doctor nope is better from vendor because it does come with the stability perk. The shadow price has a small mag, only downside, its 25... but its an all rounder, same as the vanquisher. for low level strikes, the high recoil, big magazine low impact autos are fine, but at higher levels, the all rounders such as vanquisher and shadow price are alot more effective
