Brand of Sacrifice

Your conflicts with daemons have left you branded, in turn making you supernaturally aware of the supernatural. You are aware of any fiends, celestials, monstrosities, undead, and aberrations that come within 200 feet of you, but not their location. If a CR 17+ creature of any of the aforementioned types comes within 200 feet of you, you lose 1 hit point as the brand begins to bleed, and you lose 1 additional hit point for every round thereafter the creature remains within 200 feet of you. You cannot lose more than 10 hit points in this way per long rest.

Additionally, unintelligent daemonic creatures are supernaturally drawn to you, and are immediately hostile to you. Daemonic creatures with an intelligence higher than 3 cannot detect you supernaturally in this way.
