Many creatures in the world are considered spirits, due to their ties to natural and supernatural forces. Though spirits vary greatly in form and ability, they have some traits in common. All of the following creatures are considered spirits for all game purposes:
- All elementals, fey, and spirit beasts
- All incorporeal undead
- Any creature currently in astral form (but not one physically present on the Astral Plane)
- All creatures with the [Spirit] subtype.
- Any creature summoned, called, or created by a spell or ability with the [Spirit] subtype.
