You alter how an item's or a spell's magical aura appears to effects like detect magic. You can hide the aura entirely, have an item register as a common item of lower level, or make a spell register as a common spell of the same or lower rank. A caster using a detect magic or read aura of higher rank than disguise magic can attempt to disbelieve the illusion using the skill matching the tradition of your spell (Arcana, Religion, Occultism, or Nature); further attempts by the same caster get the same result. You can Dismiss the spell.
