Magic Aura

With a touch, you place an illusion on a willing creature or an object that isn't being worn or carried. A creature gains the Mask effect below, and an object gains the False Aura effect below. The effect lasts for the duration. If you cast the spell on the same target every day for 30 days, the illusion lasts until dispelled.

Mask (Creature). Choose a creature type other than the target's actual type. Spells and other magical effects that detect creature types treat the target as if it were a creature of the chosen type, such as Detect Evil and Good, Divine Sense, or the trigger of a symbol spell. Spells and other magic effects that affect specific types of creatures, such as holy water, Divine Smites, or Slaying weapons, still affect the creature as if they were their true creature type, which may reveal this spell's deception.

False Aura (Object). You change the way the target appears to spells and magical effects that detect magical auras, such as Detect Magic. You can make a nonmagical object appear magical, make a magic item appear nonmagical, or change the object's aura so that it appears to belong to a school of magic you choose.

You choose a creature type and other spells and magical effects treat the target as if it were a creature of that type or of that alignment.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the time it takes for the spell to become permanent is reduced to 20 days. When you cast this spell using a spell slot of 7th level or higher, the time it takes for the spell to become permanent is reduced to 10 days. When you cast this spell using a spell slot of 9th level or higher, the spell instantly becomes permanent until dispelled.
