Cursed Technique

Cursed Techniques, commonly shortened to simply Techniques, are are a form of advanced jujutsu that grant the user specialized abilities. Different types include innate techniques, barrier techniques, shikigami, and all jujutsu they encompass as well.

Description
If cursed energy is comparable to electricity, cursed techniques are home appliances that use cursed energy to fuel them. Cursed energy can be used as a blunt force, or to reinforce the body, but these applications are not considered cursed techniques. Instead, cursed techniques flow cursed energy into them to carry out a specific function, granting the user a special ability.

Innate Techniques
Innate Techniques (生得術式) are intrinsic supernatural powers congenitally engraved into a sorcerer when they are born. They generally manifest around the age of five or six and are completely unique to the respective user. These techniques cannot be copied in most cases because they require innate talent to possess. For those who possess an innate technique, it is considered to be 80% of their skillset.

Even among sorcerers, it is rare to possess enough intrinsic talent to be born with an innate technique. Those born with one can train theirs to be stronger even if it is considered to be weak once they first learn to use it.

When someone refers to their own personal cursed technique, they're generally talking about their innate technique.

Inherited Techniques
Inherited Techniques (相伝術式) are innate techniques that can be passed down through the bloodlines of sorcerer families. These techniques are especially powerful even among cursed techniques. Cultivating and passing down these techniques is what allows sorcerer families to maintain their prosperity in the jujutsu community.

Inherited Technique users have the advantage of being equipped with a manual on how to use them. However, passing down a technique through generations also presents the issue of other groups learning how the ability works, along with it's shortcomings.

Barrier Techniques
Barrier Techniques (結界術式, Kekkai Jutsushiki) are techniques that allow the user to erect and manipulate barrier walls. They can be used to conceal entire areas, shield the user, or trap opponents, among various other uses. Barrier techniques are the simplest and most common cursed technique, as they require no innate talent to utilize.

Anyone with enough cursed energy can learn to erect barriers, such as non-combatant Jujutsu High managers. However, advanced barrier mechanics can be complex for even the most talented jujutsu practitioners. Many strong sorcerers with innate techniques can't perform barrier techniques. For example, creating a barrier is simple enough, but making it so only certain people can exit requires advanced skills.

Extension Techniques
Extension Techniques are any type of attacks, spells, or abilities derived from the user's innate technique. (i.e. Collapse is an extension technique of Kento Nanami's Ratio Technique.)

Reverse Cursed Technique

Cursed energy stems from negative emotions and human bodies can't be regenerated by it. In order to generate positive energy, negative energy must be multiplied together. This can be achieved through a reverse cursed technique. Doing so is simple enough in theory but it requires extremely sophisticated cursed energy manipulation that most sorcerers can't pull off.

Shikigami

The ability to conjure Shikigami (式神) is also considered to be a cursed technique. While some shikigami users may not have their own innate technique, their shikigami may possess special powers. Additionally, some innate techniques like the Ten Shadows Technique revolve around summoning shikigami.
