My question is whether natural armor of a Sorcerer gained by Draconic Resilience (13 + Dex modifier) does stack with the bonus on natural armor by, e.g., the werebear template ('a +1 bonus to AC while in boar or hybrid form (from natural armor)'), which would make it 13 + Dex modifier + 1 bonus to AC?
To me it seems to be a double application of natural armor but then again if the character would be wearing a half-plate the AC would be 15 + Dex modifier (max 2) + 1 bonus AC, right?
I got a lot of answers from Does the Sorcerer feature Draconic Resilience work with shields? but I cannot filter the answer to my question out of it.
