All magical effects and magic items within the radius of the
spell, except for those that the character carries or touches,
are disjoined. That is, spells and spell-like effects are
separated into their individual components (ending the effect as
a dispel magic spell does), and permanent magic items must make
successful Will saves or be turned into normal items. An item in
a creatures possession uses its own Will save bonus or its
possessors Will save bonus, whichever is higher.
The character also has a 1% chance per caster level of
destroying an antimagic field. If the antimagic field survives
the disjunction, no items within it are disjoined.
Even artifacts are subject to disjunction, though there is
only a 1% chance per caster level of actually affecting such
powerful items. Additionally, if an artifact is destroyed, the
character must succeed at a Will save (DC 25) or permanently lose
all spellcasting abilities. (These abilities cannot be recovered
by mortal magic, not even miracle or wish.)
Note: Destroying artifacts is a dangerous business, and it is
95% likely to attract the attention of some powerful being who
has an interest in or connection with the device.
