There's a blood spell that boosts all paths by 2 for the duration of a battle, at the exspense of horror marking the caster and calling a bajillion horrors to eat everything in sight. If power of the spheres boosts holy, the blood spell probably does too. BTW: comunion definatly used to, not sure if it still does. Dead heroic prohpets could be revived with ritual of rebirth, and, after six months, made into prophets again, further increasing their holy skill. That was in Dom2, not sure if you still can.
