1e by RAW capped at -10 for everything, I think, though I can't be arsed to haul out my DMG and find the page right now. I can't offhand think of a way to get a PC below about -12 in any case: field plate +5, shield +5, and dex 18 gets to -12 by my math. Oh, I suppose Boots of Speed or a Cloak of Displacement could give a further bonus in the right conditions; but to get all that you've got some stupid-expensive and stupid-rare magic on you.
Not sure if 2e kept the -10 limit or not.
We have already seen that a 2e gold dragon did not adhere to that limit, as the last two have AC -11 and AC -12.
In 1e, while age categories affected things, I'm not seeing evidence that armor class was among those things, so...apparently all gold dragons had AC -2. Given Bahamut and Tiamat themselves had only AC -3, it seems pretty unlikely that age categories affected AC that much. Of course, the big problem with this is that someone playing a Fighter with a powerful magical weapon and some other benefits could quite easily hit even
the dragon-gods themselves even with relatively poor rolls. (And, having searched through a 1e DMG, I'm not seeing anything with an AC lower than -8, and only two instances thereof: Demogorgon, and Will-o-(the)-Wisp.)
But all of this points to the real flaw with descending AC. The idea with descending AC is that it is rooted in
ordinal numbers: first place, second place, third place, etc. That is, if you have AC 1, you have "first-class" AC. If you have AC 2, you have second-class AC. Etc. Ordinal numbers
are not meant for arithmetic in the first place. You can't say that second place
plus third place equals 4th place. Nor can you say that if you subtract 2nd place from 4th place, you....somehow get 2nd place again. That's patently ludicrous nonsense. And it gets worse when you have to start inventing "zeroth place" and "negative-first place" and "negative-second place" which is
better than "negative-first" place etc., etc.
People struggle with this for the very simple reason that the concept that originally went into it, that ACs were
place values on a qualitative chart rather than
numerical bonuses on a quantitative chart, is completely incompatible with the way that it was actually used. It's ordinal data, but being treated with cardinal arithmetic (where 1+2=3 and so on.) The mere existence of a shield that could somehow "bump" you up to being
zeroth-class AC is already an admission that the system is at war with its own conception.
Or what we've done to our education system....
Arithmetic is
not one of the things wrong with our current education system. There's plenty to complain about, but that specific part isn't really that much of a concern.
No argument here.
Honestly not sure what's being said here. Are you saying people aren't washing?
