By means of this spell, the spell caster can dispel any phantasmal force — with or without audible glamer — cast by a nor-illusionist; and the spell has the same chance of dispelling any illusion/phantasm spells of another illusionist as a dispel magic spell (qv.) does, ie. 50% base chance adjusted by 2% downward, or 5% upward, for each level of experience lesser/greater of the illusionist casting the dispel illusion compared to the illusionist casting the spell to be dispelled.
