Domain Expansion

Domain Expansion" is a technique where cursed energy is used to construct a three-dimensional enclosed space or pocket dimension covering the surrounding area. Used for trapping a target in a zone

Description
The user has complete control over the area within the technique. The technique allows users to gain the upper hand in a fight over a stronger opponent. It more or less ensures that any techniques used by the Domain's creator will hit the opponent, although this is not always the case. The user is able to use their techniques to their maximum potential in their Domain Expansion.

A Domain Expansion is completed with technique; where a Domain Expansion is incomplete, it is somewhat weakened. A Domain Expansion can also be broken by an opponent where the user is beaten, the opponent expands their own domain and it overpowers the user's, or a third party breaks in from the exterior of the domain.

The domain is focused on keeping the opponent inside the space, it is naturally weak to those attempting to break into the space.
