Rite of Gaian BloodEdit
This rite causes the subject's blood to course with the living power of Gaia. The blood is painful to vampires, who can take no nourishment from it (though it does not harm them). Wyrm beasts also cannot abide the taste of the blood, or the smell of the subject. They must make Willpower rolls in order to touch the subject, or do anything that will bruise the subject, or cause her blood to be spilled.
The ritemaster rolls Wits + Rituals against a difficulty of 7; only one success is required. The effect lasts for one lunar month.
