Pangaea and blood advice needed.

[Cor2]

Hypothetically lets say I was playing MA Pangaea and I was setting on 100+ blood slaves. My only blood mages are those national 3n2b ones. What would be a wise thing to do with those blood slaves?

Right off the top of my head is cross breeding, and rain of toads. Are there any better options?

[quantum_mechani]

I would choose dark vines above crossbreeding.

[Hadrian_II]

I'd use the slaves to forge blood stones.

[Humakty]

You could also empower one of your earth mage to summon demon knights.
Would need a strong blood economy.

[Folket]

Go to blood 9 just to get demon knight seems like a waste of resources. I would just forge blood stones and LL protection.

[Humakty]

Why blood 9 ?
You can cast the low level one repeatedly.
Or do I miss something ?
If I remenber you don't need a huge number of them to kick in a real punch.
