mentions of death warning, as the title would suggest! these are just ideas i think would be cool to use in a story (hhhh like an SMPEarth one shot or two...)

So while every server works different, here is the main idea; 
Every time a player dies, when they respawn, they get a scar from it. And these scars build up over time, and they keep the all memories up until they take their final breath, which means they remember how and what it felt like to die.

so just to give you an idea, imma use Tommy in the dtsmp since he seems to die a lot. Okay, so let's say he's out hunting for discs and skeletons get the best of him, when he respawns Tommy has a scar from where the fatal arrow hit, as well as a vague ghost pain. (respawn points are wherever the player slept last unless the player or server specifies where they want to respawn through other means) but over time, as he gets exploded, shot, or stabbed, all of those scars build up on his person as long as he in on that server. While players try not to kill their fellow server mates because they all know how painful it can be, let's say Dream decapitates Tommy, when Tommy respawns he will have a scar across where Dream hit him. (haha this is basically just an angst prompt) if someone dies in rapid succession, side effect can occurs.

Over time, some smaller scars can fade out, but most scars will stick around for a while. Now, there are exceptions to scars disappearing if you change servers. Scars like that symbolize a very important part of a player's run, so deaths with a lot of emotional build, like a long time hardcore world death or a player's first death.

So what about death through poison, starving, drowning, or any other non-external means of death? well it varies, but say Tommy was poisoned through a splash potion; when he respawns, he would have feel like he was choking for a while, taste of the poison, and just generally be nauseous. Or for drowning he feel a similar chocking feeling. As for fall damage, it would be something like soreness in the ankles and knees.

Exceptions to and with servers; so servers like Hypixel work different than SMPs, almost no scar you get is permanent unless it falls into the exception category, but most just disappear once you switch lobbies or join a new game.

Maybe I'll go into more detail with this in the future, but if you have any questions feel free to ask! Also feel free to use this idea, I'd love to see it, I'm sure I'm not the first to come up with this, but I dont know I think it's just a cool idea that would be cool to see more of
