What type of creature is a naturally-ocurring but magical beast from another plane? Beast? Monstrosity? Do #dnd5e types assume a Prime Material point of view? #DnD @mikemearls @JeremyECrawford Depends – magical abilities = monstrosity. Mostly mundane = beast (exceptions here and there). Derived from the essence of a plane = fey/celestial/fiend/elemental
