For blood hutning taxes set to 0 and 5-6 levels worth of blood hunting(count a dousing rod as 1 level) per 5k_ population province is good(try not to hunt provinces with huge pops or pops lower than 5k). For father illearth swap the shield for a charcoal shield and the ring of the warrior for a lucky pendant, also consider swapping the horned helm for a horror helm.

For the arch devil try dual swords of swiftness, horror helm, some good armour(i like chainmail of displacement), boots of quickness/boots of the messenger, ring of regen/pendant of luck and amulet of resilence. I like to script him to phoenix pyre, fire shield attack rear but if you havnt got pyre try fire shield, a fire evocation, attack rear. He gets 8 attacks per turn at 2 squares(so 6 human sized enemies) with very nice strength and attack.

You should bump up your blood economy, get some vampire thugs with a weapon(the more attacks/AoE the better), a charcoal shield, horror helm, heavy armour, boots of quickness, lucky pendant and whatever you find helps(the boots and helm arent neccesary). If they have lifedrain(im not sure if they do or not) then forget the weapon. These guys arent incredibly tough so either send them out in groups or preferably accompanying armies(they cant get surrounded and reduce losses)
