Legends and Lore
With an Arcana or Religion check, characters can learn the following:
DC 10 A shadow symbiote is an intelligence ooze that hates light. Any humanoid can host a shadow symbiote.
DC 15 Shadow symbiotes can assimilate with humanoid corpses, but they prefer living hosts.
DC 20 While a shadow symbiote is inside a host, the only way to harm it is by burning its host body with radiant energy
While it lived, the shadow symbiote knight was a powerful martial champion. In death, it is a puppet of a shadow symbiote.

4 DC 12 Perception check: gray slime around a small hole or crack
5 Creatures' shadows seem to act independently of their owners, making mocking and threatening gestures
6 Areas of darkness chill the body with life-sapping cold. While in darkness, each creature that isn't resistant or immune to cold damage gains a level of fatigue, which is removed only when the creature enters an area of dim or bright light
Shadow symbiotes lurk in tombs. They often bond with corpses and graverobbers, using these bodies to roam the world.
