So in the End Times so far, a few Daemons characters got killed during fights. Is there any consequences for them when they die on the mortal realm? Does it banish them for a while, or are they free to come back whenever they want/can? Or does it hurt them and they need to 'heal' back?

Always wondered if there was any drawback for them getting killed, or if it was more of an annoyance to them.
