NPCs don't get death saves. If you're a player character you probably already have more than 4hp. Unless you're a wizard with 6 or 7 constitution… If you are a wizard can you teach me some magic tricks?
A 1/4th chance of of death is better than none. Then I just need to make sure to lower my constitution and find an attacker with good dexterity. That makes it 3 quarters. If we allow the use of the "Oops all 6s" joker from Balatro that becomes a 4 quarters (100%) chance unless I for some reason turn out to be a player character.
