@JeremyECrawford If a target under the effects of polymorph reverts due to dropping to 0 hp from suffocation, do they now have full lungs?

If you're suffocating and change forms, you're still suffocating, unless the new form counteracts it somehow. #DnD https://t.co/7XtK85jH7D

@JeremyECrawford @Dior_Saursi so, if polymorphed into a fish, and you suffocate on land, revert back to humanoid = breathing or no?

If you assume a form that can breathe in the environment that was suffocating your previous form, you breathe. #DnD https://t.co/fBnzc1Fuh1
