[Fuu looks at the book with great interest. She had no idea what to expect--a staff, a wand, nothing at all?--but it looks like a magic tome. Kind of like what mage units in her favorite strategy game come equipped with.

You know, Water Sigil.

She watches the book as well as L'Arachel's movements as the woman casts the spell. Even watered down like this, it's an impressive display, and Fuu can well believe that it would be lethal at full power. And, she notes, it hits the target dead-on... or rather erupts from it; what a distinctive form. She claps appreciatively.]

How astonishing! [She almost says lovely, but this is magic that's supposed to kill people.] So the power comes from you and that book? It must take an admirable amount of study to become skilled in it.
