Corruption of BloodEdit
The character’s blood, spittle and sweat are laced with necrotic fluids. He need only touch someone barehanded to inflict a moderate Sick Tilt [CofD 286]; if he injures someone with his natural weapons (even bashing damage) he inflicts a grave Sick Tilt. Moreover, when the Sick Tilt ends (or immediately, outside of combat) an infectee must roll Stamina + Resolve, penalized by the character’s Shadows (for a moderate sickness) or his Shadows + Stamina (for a grave one) once an hour to avoid taking lethal damage equal to the character’s Shadows, a number of times equal to the character’s Stamina.
Drawback: The character’s fluids are always necrotic. He cannot touch anyone without infecting them.
