@JeremyECrawford Are there any creatures that are inherently magical–that would necessarily be sensed by Detect Magic? Constructs, for example, or undead?

No creature type is inherently magical for the purpose of something like the detect magic spell. In fact, there are no general rules associated with any creature type. #DnD https://t.co/n7poZxHSyG
