Mark of Sin

'''The “Mark of Sin” is an ancient use of power gained by making a deal with a sinner. How one gains this mark is they brand themselves with a special marking that can be found in old demonic Ruins. While a person has this mark, they can make people feel the pain & suffering they caused another person. If the person with the mark is being hurt, the less pain they will feel and the higher their Endurance/Defense will rise. However there’s a downside to this power, if pushed past their time limit or limits each time it is used it will start to eat away at the users mind, slowly driving them insane.'''
