Karl started his plan for the day with a combination of [Evolution] and [Beast Form].
The idea was that it should trigger beast form to give an appearance that would mimic their natural bloodline, in a form the same or higher than the bloodline that they currently possessed, while favouring the beast.
For Rue, that would be a Shadow Dragon.
If it worked, it would be perfect, and both of the skills were common enough that it wouldn't be horrifically restrictive to cast.
The combination created [Greater Beast Form], but as he finished it, Karl realized that he might just be able to use [Unholy Beast Transformation] on Rue. Shadow Dragons seemed like the sort of unholy magic attuned sort of creatures it would like.
So, Karl made plans to try both on her to see which one worked.
But he couldn't in good conscience try out new spells on the Princess without knowing what they would do.
He obviously had to try them on himself first.
