Sync Ring

When you attune to this ring, choose a blank book you are touching. Thereafter, whenever you write something using the hand that wears the ring, a copy of your writing magically appears in the chosen book. Magical writing, such as a spell copied from a Spell Scroll or a glyph inscribed for the Glyph of Warding spell, is transcribed literally but is nonmagical. If no blank pages are left in the book or the book is on a different plane of existence than you for more than 24 hours, your Attunement to the ring ends.
