It's 0 in 216. 1 in 216 be an /18/. OK, same bonus, but still, not a 19. Not quite as strong as your average ogre - ogres not really being known for work'n out and stuff...Except they don't, largely because of bounded accuracy. An ogre, for example, has Strength 19. The chances of any random human having Strength 19, given 3d6 distribution rather than 4d6 drop lowest, is 1 in 216.
You can't play the relatives of gods anymore (no Demigod option I'm aware of) so that's conveniently moot in 5e.There are conflicting accounts as to whether his grandfather was or was not Zeus. As with any superhero origin story, it underwent several revisions, and there is no single definitive source on that.
Or another few degrees of freedom in which the DM is Empowered.If PC rules don't apply to NPCs, then we don't have any real rules for governing NPCs, which is a massive shortcoming of the game.
Also 'unplayable' in that same sense: 0D&D and AD&D. Really, only 3e used virtually the exact same rules for PC & NPCs - and even it had NPC classes.It would make the game unplayable in exactly the same manner which 4E was unplayable
So not 'unplayable' at all, then.
