The Abjuration attack is a form of arcane cryptanalysis designed to deal with the prevailing idea that even weak arcane ciphers can become very strong by increasing the number of verbal, somatic or material elements, which can ward off an arcane differential attack. The Abjuration attack works in such a way as to make the number of verbal, somatic or material elements in an arcane cipher irrelevant. Rather than looking at the data-randomizing aspects of the arcane black/white cipher the Abjuration attack works by analyzing the metamagic key schedule and exploiting weaknesses in it to break the arcane black/white cipher. The most common one is the metamagic keys repeating in a cyclical domain rotation.
