Cruciatic Sympathy causes the Target to feel the pain and suffering it inflicts on others. Whenever the accursed deals damage to a living creature, it takes half that amount of damage as Psychic damage, and as long as the victim has this Psychic damage it is wracked with pain.
In addition to the above, if the victim successfully affects another creature with a condition, the victim must succeed at a Soul Contesting Roll against the effect’s DC or be affected by the same effect for as long as the creature it affected has the condition.
