Sixth Sense Feat 6Occult Psychic Source Dark Archives (Remastered) pg. 26
Your psychic abilities also allow you to detect the lingering thoughts of spirits and similar entities. While you're exploring but not
Searching, the GM rolls a secret check for you to find haunts that usually require Searching, as well as spirits, creatures on the Ethereal Plane, and beings made entirely of spiritual essence, such as celestials, fiends, and monitors.
You can also potentially notice ethereal creatures and spirits inside solid objects, provided they are within 30 feet of you. This applies while Searching,
Seeking, and on the automatic secret check from Sixth Sense. You can still notice spirits only on a successful check, and you can't see them if they're more than 5 feet inside an object.
When you notice a creature with your Sixth Sense, you also learn its location, making it
hidden to you if it had been
undetected.
