[@Expolar]Okay, working on choosing a different name at the moment, and as for Fetid Rebirth, that one is basically raising the dead, though main difference being that to acquire the effect it requires taxing rituals and lots of prep time, as raising the dead isn't his specialty when it comes to magic. As for what happens to the Reborn once Nidhogg bites it, they won't die instantly. First they'll lose their ability to reason and think, followed by a loss of motor skills and a increasing rate if decay as the magic holding them together falls apart, in the end leaving them as little more than a pile of necrotic ooze. It's a slow process that would take anywhere from a month to 4 to even a year depending on the willpower and resiliency of the individual.
