Again, then shouldn't its AP be "at least 9-B", if it could do everything Thorkell's first key is able to do AP-wise, but even more casually? I'm not saying it's unable to go break through a stone wall, but why are you assuming that it can take several punches that can blast through stone walls? That's something Thorkell is casually able to do and something you're ASSUMING the big croc is able to handle.
Fair enough.
How does it have Thorkell beat in stats when he Thorkell has better feats and AP, and is the one with better stats? The only thing the big croc is superior in, is height and weight.
It'd actually be the other way around, but okay. The bic croc is a big target for Thorkell who can easily deal injuries to it. The big croc would have to be lucky to be able to land a hit on Thorkell.
You still didn't answer me whether Thorkell is barehanded or has his axes, cause so far, we've been only talking about Thorkell without his axes.
