I always thought that they worshipped the horrors, but that the horrors really didn't care (except possibly for the awakening God, if he is some kind of horror.)

Even if the horrors are somehow in charge, their ability to enter our reality is pretty clearly limited, so it'd make sense for them to be remotely summoned or summoned in combat and then to vanish.

I was playing this position and I just didn't see a lot of reason to bring blood slaves with me into combat, and sacrifice them to my pointlessly evil religion. Almost all of my combat magic was astral, in fact. That's no good, if you're going to be the Horror Scourge, you should show up in combat with a *lot* of blood slaves.

They could have a blood-holy spell which blessed all of your horrors and also provided any of the following bonuses (drawn from the bitmask on effect 10). I'm not listing any bonuses which are already available as a bless or which wouldn't really benefit a horror much:
* Luck
* Barkskin
* Boost Strength
* Pain Transfer (?)
* Resist Fire or Cold
* Cold or Heat Radiation
* Stoneskin
* Holy Avenger
* Boosted MR (cumulative with astral blessing)
* Ironskin

So, for example, you could have a combat spell which blessed all of your horrors (all of your sacred magic beings) and made all of your horrors lucky. It'd be blood/astral, which is fine since all of your guys are blood/astral/holy anyway.

Likewise, a variant of astral healing that cost blood slaves and only healed your horrors.

The Astral Claws don't provide enough horror marking to make combat-summoning of conventional horrors really worthwhile, which is too bad, because as the horror scourge it'd be cool if you horror-marked people and then sicked horrors on them.

Boosted national versions of astral geyser and other horror-marking spells would be nice as well, especially if you had more reason to summon independent horrors.
