The question is the title. I've been playing with this group for a few months now. Everyone else has been there for at least two years. Recently we had a combat where we had to make death saves for the first time since I joined the table. I'm first in initiative and about to roll when the DM rolls behind the sceen and starts on the next person's turn. I ask him for a second so I can roll my death save. He tells me he already rolled it and we're moving on.

I was kinda dumbfounded as I've never had a DM make a roll for my character without asking (especially a death save) unless they were intentionally trying to kill them behind the screen. I ask if it was a success or failure so I can mark it on my sheet. He says I don't get to know. Nobody else is reacting so I assume it's a normal thing with this group, but I've never seen it before. I stay quiet for the rest of the game and find out my character lived.

Afterwards I ask him if I can roll my own death saves, but he insists we're not allowed to since it makes things more fun if nobody knows who's dead. I found out that another DM in the same group also rules it this way, but has offered to let me roll and whisper the results since he thinks it unfair I keep stumbling into house rules nobody told me about.

So how does your group handle death saves? I'm curious.
