...and their flesh and blood removed to be turned into parchment and ink so you can record your grandmother's delicious chicken caserolle recipe.
Then, and only then, does anything begin to approach creepy.
I'm sure you mean character sheets, good sir.
Also, I think the good/bad luck mojo of bone dice made from another person would depend on their role at the table. If they were a GM, then the dice are technically both a GM and also GM dice. it would be good luck for another GM to use the dice, and bad luck for another player to use them. (Since the touch of a GM is well known to destroy the roll of a dice, and that GM dice hate the players.) It would also be important to keep them seperate from player dice at all times, since contaminated GM dice are well-known to become murderous towards players.
If it was a person who played exclusively and never ran, then then dice are technically a "player". In this case they actually work as a buffer from GM dice rage. As mentioned before, it is well documented that the touch of a player or their dice makes GM dice angry, and that GM dice will try to destroy the player who was foolish enough to contaminate them. Here the bone dice trick the GM dice, causing them to target the person whose
bones were used. Since that person is already dead OOC, there is very little that a dice roll can do to them.
WARNING: If that player's PC lives on as an NPC they are in gave danger. They should be shunted into a forked story arc or alternate dimension (if available) to avoid serious risk of death or dismemberment.
