Dow just laughs.
A body is just a vessel for the soul. And magic can very easily put a soul into a new vessel. Want to know a secret about Emily and Veera? Well you know they both are liches right? Well do you know how a person becomes a lich? They take their soul, and remove it from their body, and place it into something else. Then they let their body die, and reanimate it. By doing so, it makes them basically immortal. Only way to kill them is if you find where they hid their soul, destroy it, then kill their body. You could chop Veera or Emily to tiny pieces, burn it in a furnace into ashes, blast those ashes with holy energy and their body would reform after a while perfectly fine so long as their soul is fine.
