You place an illusion on a creature or object you touch, changing how it appears to divination spells and magical detection for 24 days. Choose: False Aura (creature/object radiates a magic aura of your choice, or none) or Mask (a creature appears to be a different creature type to effects like Detect Evil and Good). A creature that succeeds on an INT (Investigation) check vs. your spell save DC sees through the illusion.
