1. Its a quick jutsu to use in battle, allowing it to be mobile in many situations.
2. its great for combos it kinda restricts the opponent.
3. It can burn the opponents feet making it hard to move around.
Disadvantages
1. The line of fire is very predictable and straight.
2.Its location based can only be used on hard ground, idiotic to use on water..
3. Its streaming based meaning you would have to constantly focus.
Combos and Strengths Well I would first blind the opponent using a couple flash bombs and try to disrupt their hearing with a loud technique, then send this out their so they wont notice it.
Ways to counter/Weaknesses Id disrupt the ground and make the area where it runs turn to mud so it won't be able to move around the ground. Another is drown the place with water. Its obvious but yolo.
