I think Razira's just very forward and blunt with her words, I'd say it's more in-character for her to refer to the "arm" of a tunic rather than the "sleeve".

I feel that I usually fail at making her dialogue quite as uncomplicated as it should be, she's not a simpleton or anything, she just doesn't have much need for flowery prose. It's hard to write in a voice that's not your own.

In our game, I don't think there are any priests anywhere capable of casting Regenerate - although Konsi's getting pretty close!
