Description:
A much more powerful version of the Water Release: Five Feeding Sharks, the user creates one thousand sharks out of water that enter into a wall formation and rain down to attack the opponent. The user can control these sharks with mere thought. The sharks have sharp teeth able to rip through a body easily, as well as high speed in water. If the sharks are around a water source they can regenerate, takes two post to regenerate, and only 10 sharks can do this a topic.

Extra Information: The person who uses this cannot use other water justu while this justu is in effect. Must be from kiri.
XP Cost: 50

So as long as they are near a water source they can regenerate? Does this mean they can't be destroyed?
