    Keys: Innate Technique

    Enabled · After character · Order 10 · 100%

    Entry settings

    Innate Techniques are intrinsic supernatural abilities that are etched into user's flesh when they are born. These techniques continuously develop and engrave themselves within the user over time, eventually manifesting within a sorcerer around five or six years old. These abilities can be inherited from a predecessor within the same clan or a completely unique ability may manifest regardless of their heritage. These techniques are nearly impossible to mimic or replicate due to their proprietary nature

    Keys: Inherited Technique

    Enabled · After character · Order 10 · 100%

    Entry settings

    Inherited Techniques are innate techniques passed down to sorcerers in the same bloodline. While sorcerers who don't come from prominent clans can inherit innate techniques, those obtained hereditarily from the ancestors of the Big Three Families especially carry the title of inherited technique.

However, passing down a technique through generations also presents the issue of other groups learning how the ability works, along with its shortcomings

    Enabled · After character · Order 10 · 100%

    Entry settings

    Reverse cursed technique processes negative energy into positive energy by taking two sources of cursed energy and multiplying them by one other. As a result, the energy that destroys becomes energy that creates, and negative energy becomes positive. Producing positive energy is extremely complex and difficult to perform for most jujutsu users. Positive energy is used most commonly for healing. While very few sorcerers can utilize reverse cursed technique, there are even fewer that output it to heal people other than themselves. Cursed spirits are vulnerable to positive energy as it can compromise the integrity of their cursed energy based bodies. When positive energy is blasted directly into a curse, it compromises the structure of their body and causes them to disintegrate

16. #16Cursed Technique Reversal (Cursed Technique)

    Keys: Cursed Technique Reversal

    Enabled · After character · Order 10 · 100%

    Cursed Spirits are a race of spiritual and conceptual beings invisible to humans, incarnated from the cursed energy that leaks out of humans over time due to their negative emotions.

    The Cursed Womb: Death Paintings are nine cursed objects created with the mixed blood of both a cursed spirit and a human. Death Painting Wombs No. 1-3 are special grade. While still existing as cursed objects, the Death Painting Wombs appear as small human-like fetuses that cannot act independently. When ingested by any human, a Death Painting Womb can incarnate into a full half-human half-cursed spirit capable of using jujutsu. The vessel can be anyone, even a human with zero innate talent or the potential to become a sorcerer. Fully incarnated Death Painting Wombs are considered on the level of a special-grade cursed spirit. Due to their flesh and blood bodies, these beings can be seen by normal humans, and even sorcerers can have trouble telling whether they are cursed spirits or curse users.

    Domain Amplification is an anti-domain technique that envelops the user in their domain to neutralize any opposing cursed technique or domain expansion they come into contact with. The user expands their domain thinly over their entire body like a cloak. While domain amplification is active, the user can neutralize the sure-hit effects of any domain expansion. The technique will also neutralize the cursed technique of anyone touched by the user, granting the user flexibility. However, its primary drawback is that an innate technique cannot be activated at the same time, limiting the user to relying on hand-to-hand combat

    Entry settings

    Keys: Domain, Domain Expansion

    Always on · After character · Order 10 · 100%

    Entry settings

    Domain Expansion is an advanced barrier technique and is considered the pinnacle of jujutsu sorcery. A specific hand sign or signal unique to the user is required to expand someone's respective domain. Casting a Domain Expansion constructs the user's innate domain inside a massive barrier infused with their innate technique. Within a domain expansion, the user's cursed techniques are improved and any that are activated are guaranteed to hit via a sure-hit effect.
