Tips for finding blood slaves appreciated here

Yes The more the better when you get to the point where you need blood more than research. I'd say convert them all actually. But that was just an example.

But I wouldn't place more than 5, Blood 1 + Dousing Rod in a province of 5k+ and reduce the taxes, or your unrest can get out of line (unless you have massive patrollers).

But that's just my preference. If I'm not focusing on Blood as a nation (with a Pretender/nation that can use the blood) I tend to not convert everything to a blood only income but supplement my existing gem income, gold income, with the blood income that can be overlooked.
