By the way, if you can take a different origin bonus for zombies, and the HP doubling from Asvaldr doesn't stack with Aggathon but multiplies, you can create a character stronger than your Inga. You just need to learn Battle Prowess and Defense Skill, which will result in 160 HP (80+30+50). Because of Asvaldr, they will turn into 360 health, which Aggathon will then boost to 3600. Then you can give him an engineer and firearms, resulting in a very durable and quite accurate shooter. Yes, he will be quite slow, but you won't be able to maneuver much when controlling a howitzer.

For example, antimagic and firearms. Or combat training and firearms.

Leadership, too.

— Those who taste the character's blood will either become stronger and younger or turn into ghouls (depending on will and luck).

How much blood is needed for the initiation? Can it be mixed into a barrel of wine without losing its effect? Because a Heroist could carry out some excellent sabotage: sneak into a Fortress, poison their drinks with his blood, and the garrison would cut each other up.
