I gave her one less strength than a normal assassin, reducing her from strength 7 to 4/2 +1 poison. From her pedia, it seems poison is her style, and she isn't big on fightly honestly when she could use underhanded techniques. I left her melee though, as Subdue Animal doesn't seem like it would fit her.
She often gets Aeron's Chosen quickly, making her stronger (on the offense) than in normal FfH.
I also removed all her promotions but Vampire and Marksman.
The Vampire promotion in my version however allows access to Body/Death/Mind/Shadow/Extension 1/2. (Also, the Tower of Mastery gives out Channeling III, which could give her access to Body/Death/Mind/Shadow 3. Note that all levels of spell spheres require owning the right mana instead of only level 1. ) It also provides +1 xp from combat, a little spellcaster xp, resistance to Death Damage and a weakness to holy damage. It is added to the list of promotions that can make units return as Infernal Manes when they die. (There is still a chance for each evil unit to return as two manes, and in my version one of them keeps the xp from life while both keep the unit's religion.)
I removed the Vampire unit, leaving the Calabim with normal Champions that need to gain levels just like anyone else in order to get the gift. The python Gift Vampism spell cast by the vampire is gone, replaced with 4 xml-only spells (one for a level 6 unit in a city with a Governor's Manor, one for a level 6 unit in the stack with a vampire, one for a level 4 Moroi in a city with a Governor's Manor, and one for a level 4 Moroi in the stack with a vampire).
The Feed spell is changed back to be more like it was pre-BtS, if not better: you can sacrifice any non-immortal living unit of a lower tier than the vampire (not just bloodpets), feeding restores the caster's ability to attack, and feeding on bloodpets also restores movement points, the ability to cast, and gives the vampire a portion of the bloodpet's xp. (The vampire does not cast Feed, the unit being sacrificed casts it while in the vampire's stack.)
Feasting is able to raze cities to the ground if they get small enough. (The AI won't do that though.) This still gives diplomatic penalties, of the same magnitude as razing it normally would but I could only figure out how to use the generic diplomatic effects from events instead of making it say the bad blood comes from razing a (possible holy) city. (I added a Raze spell to let other non-vampires delete badly placed cities too. As I couldn't figure out how to add an "are you sure" window like for worldspells and really don't like accidentally razing my capital, I mode this work in two parts, first adding a "razing" promotion that then allows casting the real spell.)
Neither Feed nor Feast count as casting, and both can be used after casting.
The Calabim have a Pillar of Chains UB that has the normal effect plus giving a free Governor's Manor in every city.
