I never really gave this much thought until this question brought it up: Is a dead creature's body considered to be an object? And is it still a creature?
My initial reaction was that it would not be an object, just a dead creature, since objects and creatures are defined differently. However there doesn't appear to be any strict definition of what an object or a creature actually is. And yet both creature and object are two terms that are used numerous times throughout the rule books.
Are these two terms mutually exclusive or can something be described as both?
Constructs for instance are the construction and animation of an object, but are they considered to be both an object and a creature, or are they one or the other? Is the meat suit of a once living, flesh and bone creature still a creature after it dies, does it become an object, or is it both?
Furthermore, what is a corpse in relation to spell targets?
Spells tend to define targets in terms of choosing a creature or choosing objects. Revival spells, such as Raise Dead and Resurrection, specifically target dead Creatures, whereas spells such as Animate Object specifically target objects. To quote part of Animate Object's description:
Objects come to life at your command. Choose up to ten nonmagical objects within range that are not being worn or carried. [...] Each target animates and becomes a creature under your control until the spell ends or until reduced to 0 hit points.
So if creature and object are not mutually exclusive and a dead creature is considered an object, could Animate Object be used on a corpse?
