665. Oh this is exceptionally fun!

In your campaign have either a pc or npc bard right songs about how every other pc that has died in the past.
"Brave Sir Keith was slain by the dragon on the hill,
before he could use any skill,
lost he was without a chance,
above his head the challenge was,
poor Sir Keith ... poor Sir Keith"
When ever the players enter a town where another bard is they here the songs, as it has become very popular in the region. This is especially good if you or your player have any musical tallent. My player who plays the bard plays the guitar rather well.
And I leave the next number to someone else, make it devious.
