So having skimmed through the Gamemaster Guide, it talks about allowing character death to happen to highlight the mortality of the characters but doesn’t include anything to aid a GM when the event actually occurs. No guidance on introducing new characters to the group or how to stat up a replacement character, this sort of thing would be really useful and is something that crops up through any game where either a character dies or the player wants to change their character.
I would be particularly interested in clarifying how much additional XP a second character should start with compared to the established party, especially if the character in question was killed during the campaign.
Any help with this would be appreciated.
