Take Trophy

You take a trophy from one humanoid creature you felled, but did not kill. For every creature you a take trophy from you gain +10 HP for a total amount of 100 if you have that trophy on you and show it. The creature develops an unnatural hate for you and gains the flaw (I will do everything in my power to destroy the one who did this to me). They know it was you. If the humanoid dies you lose the HP for that creature. You also know if that creature dies. That creature also knows if you have died.

A trophy might be an eye, horn, finger, ear or even the tail of a creature that has one.
