Paths of Blood

[Shovah32]

Well either you build up huge amounts of unrest(bad) or you patrol to get rid of unrest which kills your population(bad).

[Meglobob]

If your only a minor blood nation or dabbling in it in order to extend your magic, I often blood hunt at 100% taxes, only adjusting the tax rate next turn to get rid of unrest, then bloodhunting again.

You maximise revenue this way, well still getting a steady supply of bloodslaves. The population remains very stable as well. Often I will have a lab in the province so I can research the turn I am not bloodhunting.
