The Mhachi were mentioned as having their strongest magi offer themselves up as vessels for powerful voidsent, though that was in a manner that made them very dead and wasn't "safe" like how reapers utilize Enshroud as that only permits a small portion of a voidsent's essence to cross over, but nonetheless runs the risk of the same outcome as the former method if the wielder is reckless and allows their will to falter.

It does make question me just how "dead" the likes of Diabolos and other powerful voidsent are considering that destroying their vessels would not necessarily destroy their souls and other instances of killing voidsent refer to it as simply "banishing them back to the void".
