Rebekah nods her head in understanding, and listens as Sasuke begins to explain certain techniques of Fuuinjutsu.
"So, in the first technique, the user will create a barrier underneath their opponent, which erects upward and confines the target within it. However, you must be within short distance from your opponent to do so. Furthermore, if you're opponent is a higher rank than you, the barrier does not affect them at all. Although... summoning two of the barriers from below the opponent would increase it's ability to restrict a person of a higher rank (just one rank above)."
Rebekah blinks a few times, biting the inside of her cheek.
"So, I guess what I am confused about is combining the two barrier to increase its rank. Does it have to be the same barrier, or can it be a different one (a different fuuinjustsu that creates a barrier), and does it count as an extra move slot to summon the second barrier, or does it happen naturally within the first move?"
Rebekah makes her way forward, picking up one the scrolls from the untidy pile and reading it in depth, while plopping down criss-cross-apple-sauce in front of Sasuke.
"So, for this one,"
Rebekah holds up the scroll while her eyes continue to roam over it.
"The user summons a wall of mist, in which can impair the sight of shinobi within it, while also voiding sound from being heard outside of the wall. As a Jounin myself, I can use this up to mid range and for about three turns the wall will last.
Rebekah places the scroll in her lap, while looking at Sasuke, questions forming within her eyes.
"When visualizing a wall, I usually picture it standing in between two people, not people going into it. So that kind of throws me off a little. I just visualize a huge rectangle of mist the person would then reside within. It seems like it would be effective to use as a defense mechanism toward low ranking sound techniques that produce audio to inflict harm. However, you'd need to be really quick because of the near instant affects sound have, or produce the wall before hand."
Rebekah begins to pop her finger joints, waiting for Sasuke's next words.
