They're in the DMG, have been in every edition essentially.
No. It. Is. Not.
Not in the 5e DMG.
In past editions, yes, but not in the 5e DMG. It isn't there. It does not exist in that book. It jsut isn't - and no matter how much you say that it is, and assert that 'you're sure it is', and insist that it has been in the past and so it must still be... that won't make you any less wrong about this. It's not a part of 5e, and it has never been a part of 5e. This was, in fact a very deliberate design choice made with the publication of 5e, that stepped away from excessive punishment for bad rolls, with the exception of elements that were considered too symbolic to abandon - attack rolls, primarily. Death saves were given a 1-and-20 rule as well, because they embodied the whole 'hands of fate' concept, but that was it, ad that was very much a deliberate choice.
So, again.... if you want to keep spreading lies and misinformation, then please provide a quote or a source reference. It would be incredibly easy for you to prove your case, or prove me incorrect here, if you would just do that; why won't you?
