Ever since EFUSRE, I have been capable of breathing underwater even when polymorphed. Is this a bug or a feature?
Depends on how you look at it. It's a direct result of it but it never occured to me a character might not have its original appearance. Whether it's a bug or feature is not for me to say but as far as I'm concerned, air genasi are immune to choking, so I'm not changing it unless asked to.
