There have been some instances where I have been curious as to how a player met their demise. Sometimes the reason can be blatantly obvious in the dangerous areas of dungeons, but sometimes you can find more sinister ones hidden in containers or in unusual places. A feature that could investigate the body to determine in what way they player died could be interesting to relay into RP. An example would be like if John Horc was found dead in a forest known to have deadly animals, but yet the wounds were caused by a weapon type, trap, or magic.
The spell known as, Speak With the Dead, is a staple in the world's setting and could also work for this suggestion. It may be limited in scope from the standard 5 questions it allows, but it could provide things that wouldn't be known by mere inspection like potentially their name and who or what killed them (if applicable). There might be restrictions needed in place like checking if the player is still online and a certain amount of time has passed to determine when it can be used though since I can see how it could be used to metagame.
This next part is a bit of a stretch, but also to maybe have bodies that were destroyed by bashing to leave behind some trace just like footsteps do.
