In 20+ years of gaming, I have never seen a character resurrected in a home game.
I'm curious how common resurrection is assumed to be. Out of every N deaths, how often can characters expect to be raised? Does it vary for you by tier?
Raise Dead or Resurrection are as common as PCs need it to be. If they want their beloved character to return, there will be a priest that can cast the spell. But such services come at a price, which is generally some sort of perilous quest. I take death as an opportunity to tell new adventures.
Only five or six.Can you make a rough guess how many you've seen die?
Sounds fun!Interesting. I've been in games where raises are almost impossible, and in games where death is a revolving door. Heck, in one game where they were almost impossible we actually managed to find a rod of resurrection(2e) and my PC came back 5 times in one fight going against priests of Set. Freaking poison saves! I also gave our paladin of Horus-Re a crisis of faith, because I didn't have the good grace to stay in the afterlife like I should.
