Heart Of Coal

Heart of Coal [minor] by Iczer

'I'm afraid your pleas for mercy fall upon a heart blacker than even your foul deeds. Be still.'

The character's heart is a solid, semi rigid organ, that transmutes the fluid that passes through it, literally carbonizing his blood. The character enjoys a +1d6+1 to PE and 15 extra Hit Points. Blood based poisons, blood borne diseases and effects that target the heart directly or indirectly are useless against this character.
The character can also deliberately harden his heart. When he does this he becomes cool and unfeeling. For every 2 points of MA damage he inflicts on himself he gains +1 PE, gains a bonus 1D6+1 SDC and gains +2 to save vs any control of his emotions (including empathic transmission and Horror/awe factor). Spent MA returns at a rate of 1 point every 15 minutes.
