I played for Abyssia for a long time now, and experimented with hunting pretty much.
It'll be without numbers but...
SDR greatly enhances number of captured slaves, for blood mages. But level in blood magic is pretty decisive factor too. For example I had 3 SDRed Warlock Apprentice in 9k Pop province(+3 Luck, -1 Death), and they got 24 blood slaves/turn. In other words 8 blood slaves per turn per warlock. But in had to hunt sometimes in my capital with 4th level warlock, and he got something like 15 slaves per turn.
Another important thing, it's better don't use patrolling troops, sinse they kill population too fast. It's better to give peoples a break, for one or two turns and then continue blood hunt.
But one question still remains who is better 1 4th level Warlock, or two 2nd level Warlock Apprentices.
