Big Hat's Projecting Prisms

You create six pillars of clear quartz in spots you can see up to 100ft away. The quartz refracts the light around it, creating an illusory duplicate of yourself around the pillar. You can choose to cast a spell from the visual perspective of any of these pillars, the illusions appearing to have cast it themselves. The pillars have an AC of 15 and an HP of 20 and can be destroyed. Creatures can discern the difference between you and the pillars by making a successful investigation check, DC equal to your spell save.
