Life of Fear

You have extensive history with certain individuals or species, and so are marked, for good or ill, both emotionally or psychologically scarred by them, and possessing heightened knowledge about them to share with others.

At the start of combat with these creatures or persons (as determined by your backstory), take a Wisdom saving throw at DC 12. If you fail, you are frightened of the creature. At the top of each turn, you can retake the check. If you succeed, you are immune for the rest of combat.

You also have advantage on Intelligence checks to recall information about these creatures.
