I don't like silver platters. Or rings of plot protection. When I was in college there was a major game at the gaming club (14+ regular PC's and one DM). You could not stay dead. The DM always had his favorite friendly NPC appear and save us. A friend and I got into a death race to see who could die first from CON loss. After 6 or 7 deaths each we both got bored and I started a new game.
Half of the people instantly came to my table.
I've found an easy solution though. In the one game I get to play in these days I just retired a character who was turned into nothing, but still brought back. My character was in an explosion, rolled a '1' on his save, the "you really screwed up" check pointed to the artifact in my characters hand as the item I was going to have to roll for. It failed, horribly, to survive the force of the blow, and blew up on it's own (it was a staff).
If there was anything left of my PC it was atom sized.
Got a True Ressurection from the DM.
My character would accept it, so I did. Then I promptly had the character retire from adventuring to he could retire to his cottage and study magics in safety.
Worked well enough. The character is gone from active play and the DM gets to save him for whatever he was trying to do.
