Deathwatch

You sense the condition of all creatures you can see within 30 feet of you, including whether they are dead, undead, or alive. If the creatures are alive, you know each creature’s condition, including whether they are uninjured (maximum current hit points), injured (fewer than maximum current hit points), approaching death (1 hit point), or dying. This spell sees through magic such as feign death or illusions intended to hide the living or the dead.
