Those who magically pry into your mind become privy to your most frightening dreams.

Prerequisite
Exposure to phantasmal killer spell.
Benefit

Whenever someone successfully targets you with a divination spell or effect, you can send that caster a nightmarish vision. This vision functions as a phantasmal killer spell, except that the form comes from your dreams, not the other creature’s dreams. The other creature must succeed on a Will save (DC 14 + your Cha modifier) to disbelieve the nightmare and a Fortitude save (DC 14 + your Cha modifier) to avoid dying from fear.
