@JeremyECrawford Can dragons using "Change Shape" pick any physical stats? How does it determine what is class/racial feature in stat block?

A dragon's Change Shape lets the dragon pick the stat block of a humanoid or beast of an appropriate CR and change into that form. #DnD https://t.co/zDfkB3s3AN
