Heretics?

They can be useful to counter LA Ermor/Ri'Lyeh.

Another fun trick: summon a Black Servant, give him a Stone Idol (to make him a heretic) and a Bane Venom Charm and then send him into the enemy lands.

Are black servants, or undead in general, immune to the bane venom charm?

Undead are not affected by disease.

A heretic is basically an atheist preacher, I think. They lower any dominion in the province they are in, yours or the enemies'.They're just dom sappers. With LA Pythium, I use them on the frontier, to lower enemy dom, then move them out if I want to push my own dom.

I imagine they are excellent for dom-killing enemies who have been confined to nasty fortresses.
