Mordenkainen's disjunction was a powerful abjuration spell that reduced magic items and effects to their basic components, effectively and permanently canceling them.[1]
To Zakharan mages, always reluctant to acknowledge ajami names and accomplishments, the spell was known simply as disjunction, and counted among the spells of the universal province.[4]


The spell caused all magic effects and items to be broken down (or "disjoined") into their basic components. The spell even had a chance of overcoming the effect of an antimagic field if the caster was sufficiently powerful. In effect, magic items were stripped of their magic and reverted to mundane items and any spells in effect in range were instantly ended. The wearer of a magic item subjected to disjunction might try to ascertain their own willpower to try to prevent the item from being disjoined.[1]

Mordenkainen's disjunction was so powerful that not even artifacts were entirely immune to its dissociating magic. There was a chance, albeit small, that an artifact could also be stripped of its magic, also permanently maiming the magical capabilities of its wearer. Of course, the destruction of a powerful artifact ran the risk of calling the attention of powerful beings associated with that artifact.[1]


The spell required only verbal components.[1]


The spell was attributed to Mordenkainen of Oerth. By the mid-14th century DR it had found its way to spellbooks in Faerûn[5] and Zakhara,[note 1] but was considered a rarity.[4][6]
