Well that's...a little confusing if I'm honest, but I'm gonna go with not near so easy as humans. Which stands to reason given everything you've said. [K is more robust than any ordinary human. This is something Vrenille simply accepts. K is probably more robust than any ordinary norn too. That's just how it is.]

They do like to stay on brand. [Because yes, those are very much standards.] Mix 'n match is better than lucky dip though, 'specially if you've learned what cause has what effect 'n can choose how you use it.

[There's a tacit question there--it sounds like K has worked that out and is (hopefully) using it to his advantage, but Vrenille isn't going to assume without confirmation.]
