Volo's Floating Page

This magic captures a perfect image of any page of a book, scroll, or engraved inscription on any relatively flat surface you are gazing at during casting. The "page" can only be one side of a decorated surface, and the spell captures only what you see, not any hidden writings. A written contract or message or spell can be read and cast from this floating, faintly-glowing (enough to be read by, but not blind any being or hamper sight) image by the caster (only; everyone else sees a shimmering radiance of swirling chaos), which enables the caster to carry a copy of a scroll or one-page spell without risking the original.

However, the primary uses of this spell are to copy a message or convey it elsewhere, or to enable a caster to acquire an image that can travel where the caster can copy it out physically (into a spellbook or blank scroll). Until that's done, or the spell expires, the spell slot occupied by a captured image of a page or scroll is unavailable to the caster for other magic uses (though they can choose to "forget" this image to regain the spell slot, so it will be lost forever, just as it is if the spell expires before use can be made of the image). You can cast multiple versions of this spell if you have sufficient spell slots, and so carry illusory images of multiple pages for spellcasting or copying use.
