I assume this is for Divine Blessing?

Androphags and Oiorpata are both Cap-only sacreds, so their numbers will generally be quite limited. The best thing to do would be to put multiple Warrior Sorceresses among them and then order them to cast Bless until the units are out of casting range. You'll get a good percentage of them.

The two best ways of getting H3 have already been mentioned (Mound Fiend and Sabbath Slave War Sorc), but it isn't necessary to have a B1 Warrior Sorceress. An alternative is the Master/Slave Matrix depending on the type of communion you're forming. I would say that a Reverse Communion led by a Soothsayer with some kind of bow (If he casts spells, he'll fatigue/kill your WS):

1 Soothsayer (Master with Bow like BBoB scripted to Fire @ Rearmost)
3 Soothsayer (Slave)
1 Warrior Sorceress (Slave Matrix)

This will allow your WS to use DB and whatever other magic she has without fatiguing the other participants in the communion. If she was an N1 for instance, she could waste your slaves off-script when she started spamming non-Astral magic.

With the reverse communion, the 3 Soothsayer slaves can cast Soul Slay while you get some DB and Smite action off your WS.

Plus, this basic communion structure can also be combined with your Witch Kings, Enaries, and Spirit Guides (Slave Matrix, please) to augment your other magic.

The only problem with implementing this is finding Earth magic in Sauromatia. Therefore, you'll want at least a pretender who can make the matrices. Besides, a 4E bless would be lovely anyway to reduce encumbrance on your sacred armies and Witch Kings and gives access to hammers. The Earth magic limitation to this strategy will confine it to the realm of novelty unless you pick up something cool in the way of magic sites to recruit ES mages from (High Temple of the Magii?).

Other than that, I would confine your view to alternatives to blessing. What magic can I use instead?

I want to be looking at things I can do easily:

Quickness, Body Ethereal, Luck/Battle Fortune/Will of the Fates, Regeneration, Touch of Madness,

You could do a combo like Poison Ward and Foul Vapors (maybe with Hydra guards) or Winter Ward/Grip of Winter.

These are just ideas I pulled out of my rear for the purposes of example only, btw, I haven't played Sauromatia extensively.
