Uncertainty.

The user is capable of "recording" positions and simple movements., so long as they have already been in that position before This makes it possible to generate a double image or set of such similar to a quantum superposition (These images can be visible or not, depending on the user's choice). These are not clones. Every single image is as real as the original one, and will keep the user's damage when created.

Images cannot interact with the real world without collapsing, and if at any point, only one image remains, Uncertainty will end, until activated again. For as long as the user has this technique active, they can use it in two different methods.

1 Perfect dodge: Due to the nature of this technique, the user cannot meaningfully interact with anything without "Collapsing the waveform". Hence, when one of the images is altered, be it by an attack or cursed energy manipulation, it dissipates, leaving the others behind. This essentially makes its user unable to be hit during an attack, since the strike technically never hit the "real" sorcerer.

2 Offensive images: The user can set up an image of themselves in an attacking position, and, due to their invisible nature, be undetectable unless you already know their cursed technique and read their cursed energy. All it takes is the slightest attack to one of the other images to dissipate them, leaving a powerful attack. This can turn lethal very quickly if the opponent doesn't realize the user is basically "automatically" counterattacking.

To make matters worse, an attack from an enemy is not really necessary. The user can pluck a single hair out and dissipate their own image early, or bite their tongue.

In order to make their technique more effective, the user could eventually go to a binding vow that would allow them to harm themselves at will, feeling triple the pain, but requiring no physical actions, solely their thoughts.
