After a recent discussion about “What do I do if the party suffers a TPK”, which I intend to also elaborate on the blog later, I brought up a rule that I first saw in 13th Age. In 13th Age one of the interesting optional rules is that the adventurers can’t be killed by random “Chaff” type monsters. Instead, they have a “Named villain/nemesis/antagonist” rule where only the essential, named enemies can result in dispatching the players characters. When I first read this rule about “Named villains”, I originally entirely dismissed it.
On thinking about it after the discussion about avoiding TPKs, perhaps I was a bit hasty as there is actually some merit to the idea – especially depending on how strongly you tie your PCs into the overall narrative.
