Crimson Longinus
Legend
I think you can have the feel of peril even if no one actually dies. But if the chance of defeat indeed is genuine, then in the long run it becomes increasingly likely that some deaths might occur.I think there's an underlying question here of "Do you need to see peril actually have tangible results for the rules to feel perilous?"
Like, if you play 40 sessions with 5 PCs, going from levels 1-10, and no PC ever dies, did the rules still feel perilous? Does seeing several "2 failed death saves" clutch saves do enough to make the game feel risky, even if no one dies?
I'm honestly not sure.
