Halting

A ninjutsu and seemingly genjutsu all rolled up into one. Usually made to "slow down" opponents, it is a constant emission of chakra, or for skilled users, whenever the need arises, that has a specific role. Almost like chakra exertion, it is a certain chakra wave, made for a certain effect.

This chakra works better the closer the opponent is, and takes place rather instantly, for anyone in close range of the user. It puts the opponent under a genjutsu, where that in short, alters their perception of time to the user's whim.

This causes the user to perceive themselves moving normally, when in short, their central nervous system is being slowed, and their reaction time and speed thrown off to sluggish movements, where they aren't moving at all or very slowly. While it is perfectly possible for a user of dōjutsu to perceive this, it doesn't stop the effect. As nearing the user caused this, the jutsu is essentially a ninjutsu, with a genjutsu cover.

If a dōjutsu wielder sees through this, their perception of time is restored, but all that does is make them realize that they are still moving incredibly slow. But it doesn't stop the adverse effects. And if the range has spread enough, it could be impractical to dodge it, unless they are trying to escape the battle.

Even against particularly fast opponents, such as Swift Release, Lightning Release Armor, etc, this can be very effective, however a user of LRA who can see through genjutsu could potentially counter it.

Also those with a "filter" could counter it as well. It is works well against Taijutsu and fast opponents, excluding perhaps those in the higher gates (6, 7, 8).
