The player has "Humanity" and "Hollow" forms. If the player dies in their "Humanity" form, they will go into a "Hollow" form, a zombie-like version of the player. If the player becomes "Hollow", the player cannot get let other players join their own game, join other players' games, or attack other players. However, they also cannot be attacked by other players.  To get back their "Humanity" form, player must spend a "Humanity" point at Bonfires if they want to use any of the features listed above.
