You utter a supernal word of power that ousts all magic around you, bringing the weave to perfect, undisturbed equilibrium.

All spells and spell-like effects within a 20-foot radius of the caster end immediately. New spells or spell-like effects cannot be cast in this area while Mage's Disjunction remains in effect, and any such existing effects which enter the area immediately end. This property can even dispel an antimagic field, so long as the entire area of the field can be fit within this spell's area of effect.

The enchantments which give power to magic items are also affected. Magic items within the area of effect of this spell when it is cast, or which enter the area of effect before this spell ends, become disjunct from the Weave, rendering them mundane for the duration. Any attunement a creature has to a magic item ends immediately when it becomes disjunct. This disjunction persists even if the items leave the spell's area of effect. When this spell ends, any magic items which were made disjunct regain their magical properties. If they require attunement, a creature must once again attune to the items as normal.

Unattended magical items - that is, items not in the possession of a creature - risk permanent disenchantment from this spell. The first time an unattended magic item enters this spell's area of effect, roll a d20. If the result is a 1, the item is loses its magical properties permanently, becoming mundane. (At DM discretion, such a mundane item might be able to be re-enchanted by a skilled artisan). If the result is anything but a 1, the item is disjunct only until the end of the spell's duration (as described above), and it does not have to make this roll again at any time during this casting of Mage's Disjunction.

This spell poses an enormous risk to any magic users enveloped in its area of effect, including the caster. The first time a creature enters the spell's area of effect, there is a 25% chance that they will be permanently disjunct from the Weave. When this spell ends, the caster also has a 25% chance of permanent disjunction. A disjunct creature loses the Spellcasting feature and the Innate Spellcasting feature, if it has either of them, and cannot attune to magic items. A wish spell can reverse this effect, but even such mighty magic is not all-powerful. If a single creature becomes disjunct from the Weave 3 times in its lifetime, the effect is irreversable.
