How does this thread (PCs/GMs alike) feel about finishing off downed characters? Specifically in the context of (((5e)))? I was hearing a trip report from a friend about a session from a bit ago where he described the DM killing off a PC that had me doing the indecisive Larry David meme. Without getting too deep into it my understanding is that, the situation basically had a player get knocked unconscious through regular combat, fail a death save, and then have the enemies take the next turn straight up murdering him.
From a DM perspective I think the context of undead monsters preferring to tear into the victim in front of them rather than than just arbitrarily stop because the dude fell over makes sense because they're not geniuses, they're evil bloodthirsty monsters. On the other hand it feels kind of mean to delete a PC in this way when you could argue the creatures were being menaces by other party members too and they are "choosing" to kill someone than defend themselves?
Overall I'm leaning on the side that making PCs fear for their lives is a Good Thing Actually and shows that maybe you cant just run into every situation and sit there face-tanking damage without a care in the world, especially in 5e where the power level of PCs is wild.
Depends on the monster and/or the motivations of the beings doing the attacks in my experience.
If the enemy is sentient, I base their decisions on how the sentients in my game would work and their reasons. A roving Orc band for example might kill them for food, but they could also just leave them out cold so they can take them for slaves later. I tend to usually go for the latter here.
Bandits might choose to parlay a knock down into getting something off of them, since killing a party member is disadvantageous to getting the rest of them free, or they might think to get away with some GP and the knowledge to not fuck with them again if they prove to be too hard to take on.
Some magical beasts might just beat the shit out of them for showing disrespect rather than kill them, particularly beings that are more good aligned in nature... or want them alive to torture them if evil in inclination.
However sometimes they will just straight murk you. Assassins would guarantee at least a partial success on contract for example. A canny pirate might not give a shit if the wizard's down; he might slit their throat because he wants no surprise fireballs caused by a healing.
In this case, I'd probably rule that if they aren't intelligent, then the dead probably would just kill them on the spot tbh. A smarter undead, such as a ghoul, might go "need to ensure the rest are stopped before I go dead-dead again!", but a zombie has no thoughts, only hunger. They're mindless monsters after all, and the necromancer or cursed earth might want more corpses to animate later.
I will state I tend to have one or two training wheel sessions where unless you're really fucking stupid or trying to abuse it, then you probably won't die then and there. I've had that tested once, and the dice were lucky that their stupidity did not merit a first session death.
