@iDungeonMaster "do dragons have fly by attacks?"
A stat block tells you if a monster has a special flyby, as in the spined devil.

@pukunui81 The harpy’s Luring Song says the target “can” use a Dash action to move closer. Does that mean it doesn’t have to? #dnd5e The target of Luring Song can take the Dash action despite being incapacitated. And the target really wants to get to the harpy!
