Arcanist's Magic Aura

You place an illusion on a creature or object you touch so that spells from the Mystery of Divination reveal false information about it. The target can be a thinking creature or an object that isn’t being carried or worn by another creature.

When you cast the spell, choose one or both of the following effects. The effect remains active for the duration of the spell. If you cast this spell on the same creature or object every day for 30 days, placing the same effect on it each time, the illusion lasts until dispelled.

False Aura. You alter how the target appears to spells and magical effects, such as detect magic, that detect magical auras. You can make a nonmagical object appear magical, a magical object appear nonmagical, or change the object’s magical aura so that it appears to belong to a specific Mystery you choose. When you use this effect on an object, you can make the false magic apparent to any creature that handles the item. Mask. You alter how the target appears to spells and magical effects that detect creature types, such as the trigger of a symbol spell. You choose a creature type, and other spells and magical effects treat the target as if it belonged to that creature type.
