A dragon's Frightful Presence does not state that it follows the rules of spellcasting, but does it when determining a clear path of effect? If not, I don't know how to determine if it goes through cover, goes around corners, etc. @JeremyECrawford

The text of Frightful Presence states who's targeted: each creature of the dragon's choice that's within range and aware of the dragon. Nothing else is required. #DnD https://t.co/qa9YKtGdOm
