Mathilde is actually very very good with a sword. 7 might be a bit too high, but 6 is probably about right. I'll update it.
She does, but I'm sort of skipping Rite of Way. I've partially rolled it into her Duskrider rule, and sort of skipped the ability to move over terrain. Admittedly this is mostly because I didn't want to have to come up with a decent casting value for it.
They aren't actually! Dwarf-crafted removes the -1 from Stand and Shoot, while Quick to Fire removes a -1 from moving and shooting, as well as allowing you to always make a Stand and Shoot reaction.
They've been stated to be equal to full plate armour IIRC, which is a 4+.
Hmm. You're thinking BS 5 then? I chose to represent the teleportation part of Branulhune with the unable to parry rule. At least for now. Maybe if she masters it give a rule that reduces enemy WS?
Also human WS does get above 6. Kurt Helborg has a 7. As you see above though, I've reduced it.
I've fixed that. I noticed when I was typing up this reply.
