Hey Korwin. Don't worry about posting later, I appreciate all feedback and questions.
And you can send me a PM in german here or on the german forum whenever you want

Regarding Magic Path Levels. Maybe you should note somewhere total and after Char. generation. Or an Spell list?
Or an explanation in the Character Creation Walkthrough, how many spells the Char. got?
Mihaela Tomescu would have Darkness 40 (40) and Illusion 25 (50), correct?
Guidebook Vol1, Page 16, Supernatural Level:
We did not use any restrictions on things like available Martial Knowledge or Magic Levels. You can find rules for these restrictions in the rulebook and in the GM Screen book.
This is also the reason why there's no spell list. If a GM applies a different limit, the spells would change.
Maybe some pointers, what a char can do, what he is good at.
Some (like the Dark Paladin) have those explanation.
Like you said, some characters include this and some don't. It wasn't really a requirement as the Guidebook isn't there to explain all the rules, but it's there to show what characters using them look like. Of course now the trend for Volume II seems to be to include more explanations so that will change. ^^
On Calvin.: I guess you shouldn't take everything I write too literally. I often get carried away during writing and I might write down something that isn't possible in the rules.
I guess with a really good roll combined with his Quick Reflexes advantage, Calvin could manage to have a better initiative than someone who has Surprise over him, but of course not regularly.
Thanks for the feedback!
Cheers,
Peter
