Ankhseram Black Magic, also known as the Contradictory Curse, is a Black Art that involves killing.
Ankhseram Black Magic is a Black Art that allows its user to produce a black miasma that kills anything it touches. However, certain Magic Items, such as Natsu Dragneel's scarf, can protect people from the deadly effects of it. This Magic seems to be uncontrollable at times, causing it to burst out randomly, killing anything within a certain radius of the caster. However, if the user forgets the value of life, they can fully control the Magic. This Magic seemingly cannot be learned, but instead, true to its name as a curse, is brought upon someone by Ankhseram, who may do so to a person making light of the connections between life and death. Zeref explained to Mavis that the more regard the cursed individual holds for life than the more they will end up killing inadvertently and only when they no longer have any regards to life will they stop killing at all which led this Magic to be known as the "The Contradictory Curse." The main side effect of this curse is near-absolute immortality, with Zeref remarking that he couldn't kill Mavis and vice versa, even if their heads were separated from their bodies. Additionally, after some time of being afflicted with the curse, the person in question's mental state becomes warped to the point where even their own thoughts, feelings and actions become contradictory as well.
- Death Predation: A spell in which the caster releases a deadly black miasma that instantly kills any victims within its range. Its range and area of effect are, however, limited. The spell works on humans, plants and animals alike. Anyone standing close to the affected area will only be knocked out, rather than killed.
- Death Orb: The user creates a black orb in their hand which, when thrown, destroys everything in its path. (Unnamed)
- Death Pillar: The user swipes both of their arms in a circular motion until the bottom of their hands meet. The hand on top has the index and middle fingers pointing upwards, while the other hand has the little (pinky) and index fingers pointing downwards. While doing this, the user is surrounded by a dark aura. This spell creates an extremely large vertical explosion which can seemingly strike a single target out of others nearby. (Unnamed)
