Care to summarize (or link to a transcript)?Incidentally, Crawford talks about AC calculations at length in his 'sage segment' in the latest Dragon Talk podcast.

Bracers of Defense doesn't work if you wear a shield.A Barbarian with 20 DEX, 20 CON, a Shield, a Bracers of Defense and a Ring of Protection would have a base AC of 10 + 5 (Dexterity Modifier) + 5 (Constitution Modifier) = 20.
You add + 2 (Shield) + 2 (Bracers of Defense) + 1 (Ring of Protection) for a total AC of 25.
Do note that many DMs will allow the bracers to stack with the Mage Armor and Shield spells.DMG said:While wearing these bracers, you gain a +2 bonus to AC if you are wearing no armor and using no shield.
As in 1e, yes, as did the 'Armor' Spell (which gave AC 8 and absorbed hp damage before being dispelled). And, in 3e, Mage Armor, regular armor, and Bracers of 'Armor' (ie Bracers of defense) all gave mutually-non-stacking Armor bonuses.In 2nd edition Bracers of Defense gave a specific AC rather than a bonus, so Mearls is probably just mixing up the rules by edition![]()
So this is the first time Bracers arguably stack with Mage Armor?Apparently in the D&D Next 5E playtest too.
3e did have 18 named bonus types! At least triple the number in runner-up 4e, in that department.It's possible bracers didn't stack with some things in 3E, but it was still easy to stack much too many things...
You don't like the 5e rule that all things stack (except with themselves)? Or just pointing out that if you don't let all things stack (or I suppose let nothing stack), then you better have something like named bonuses.Though even 18 named bonuses is better than no inherent mechanical indicator of what stacks with what.
