Inspired by frustrating conversation I had. For those curious, that was the statblock of Caine, father of the vampires.
D&D, especially 5e, is just missing broad sections of game stuff so it can "leave it up to the DM". Other stuff is really underbaked. Degree of success, succeed at a cost, non-violent conflict, ending combat other than totally wiping the other factions...
That can be fine if everyone's on the same page, but since D&D is the mega popular game you're likely to be playing with new players, or just randos, and that can lead to tension.
