Reach zero hearts and you lose your soul. You are not banned. You keep playing.
Your soul drops where you died, in a head. Anyone can pick it up.
Your magic is still there. You cannot use any of it until a soul goes back in.
/inviteA name you take while soulless is yours only while the body is empty. Put a soul in and the soul decides your name instead.
Another caster has to do it for you. They cast Bind Soul to draw a circle, place a soul head inside, and you stand in it.
You cannot do this yourself. That is the point.
Binding someone else's soul makes you a vessel. You get their genes, their affinities and their star chart. You do not get their family name.
A soul taken from a mob works the same way, and its name is the monster's.
