Victoria Rules
That's easy enough to codify, and thus clarify, if one wants to. Your AC comes from your armour, your Dex, and maybe some other factors; and each of those factors contributes a certain number of points to that final AC.But D&D is full of these inconsistencies and ambiguities, right? I'm wearing leather armour and I have a Dex bonus. My opponent misses me by one. Did I dodge it, or did my armour absorb it?
So here, let's say your armour is giving you 2 points of AC, your Dex is giving 3, and you've got barkskin going for another 1 - so AC 16* (using upward AC for this example).
The DM would set a universal order in which these things apply. Dex comes first, then shield, then armour, then barkskin. So, in this case an attack that misses by 1 got past your Dex, got through your armour, but ran aground on your unnaturally thick hide. If the next attack misses by 2, that means it was absorbed by your armour. A miss by 4 means you dodged it; and you don't have to do much at all to avoid an attack that misses by 7 or more.
* - for whatever reason, you forgot your shield this morning.
