In a game where you are playing tomb robbing, body looting scu… uh, adventurers how do you reasonably stop PC’s scavenging from the corpse?
Just look at the name. Dungeons and Dragons. Looting tombs/vaults in dungeons, stealing dragons treasure, it’s barely justified robbery. The entire mentality of the game seems set around killing things and nicking what they find. Why would any non Lawful Good character not take advantage and pilfer an item or two rather than chuck it into a shallow grave or hand it on to a stranger who hasn’t had to work for it?
To maintain game balance I can see a reason to ease up on the loot given out until balance is restored after Johnny the Fighter got slotted and his still cooling body was striped for everything but his underwear but making the stuff vanish? A little unrealistic in most settings surely?
Let the PC’s do what they will and leave it to their choice to pass on the stuff to the church, next of kin etc or not as applicable to their alignment, personal code and morality. (Or, all too frequently, lack of

)
