To make this extra stressful, Revivify is the only resurrection spell I allow if I'm running 5e. :)
(Okay, to be fair, that doesn't mean I ban player resurrection in heroic campaigns. I just want it to be more of an ordeal, y'know? So it has to be a quest, or require bargaining with some kind of supernatural entity, or come with a price or chance of failure, etc. I just don't want it to be "I cast the spell, or go to someone who can cast the spell and pay some gold.")
