Abysya - Blood Hunt/Research problem. For Developers especially.

[Cohen]

BoH is good at blood hunting, but lacks research totally, since it can't get Magic scale. This will end up to be outgunned by magic power.

Default Abysya instead has difficulties in both of them, since:

Researchers and Blood hunters are capitol only.

In secondary castles you can recruit only expensive mages (the cheapest costs 200 gold, the other 360), that have only 2 or 3 magic levels.
In capitol you can recruit for 270 gold the warlock, your best researcher, and warlock apprentice (best researcher/price and your blood hunter).
The demonbred has other purposes usually. It can research, blood hunt and cast in battle, adding with great mobility, but it's pretty expensive, and it's capitol only too!!!

So the problem is that you have to choose if go for research, or go for blood.
Usually going for blood means other Nation not restricted to blood hunters in capitol only got before you the blood research for the nice summons and since they're limited too you end up to be able of summoning troops.
Nations like Mictlan, Jotun(with the random Vaettir Hags), or BF Ulm can recruit blood hunters in other castles, and their researchers in capitol.
Even if Abysya take 3 magic is doomed to lose the battle for the Big Devils. Even if Abysya has the skill to forge easily the blood empowering items and the base for summoning Arch Devils (Demonbred + brenzen vessel and blood thorn), Heliophagy (Warlock +1/2 blood empowering items, depending from the random), and could reach easily the Daemon Lords too.
But other blood nation with non capitol only blood hunters will take them easily. (BF Ulm has to waste some slaves for a Fallen Angel usually, 66, but it comes with B3F3, and he needs and item only to summon Arch-Devils).

After this analysys, I'd suggest to add to Abysya default a blood hunter not restricted to capitol only. Warlock Apprentice should be fine, more costy than the BoH counterpart, not sacred, even if it comes with 2 blood. Keeping in mind that Abysyan are already very expensive I believe this would be balanced if the Anthemath Dragon (the best battle mage, 3F) would be limited to capitol only.
