This magical tome is hefty and solidly bound, with metal corner caps and reinforcement. The elaborate front cover is adorned with a variety of mystical symbols around a magic circle bearing a prominent five-pointed star.
This tome can only be destroyed by being dropped into a Sphere of Annhilation, or by the will of a Greater God of Magic. When not attuned to, it appears to be blank and all attempts to write in it or deface its pages fail.
Attuned Abilities
Spellbook. If you are a spellcaster such as a Wizard who keeps spells in a spellbook, you may use this book as your spellbook. This tome always has more blank pages for you to add spells to, and you can cause it to turn to any spell currently scribed within it when you open it. The tome has an effect similar to an Arcane Lock that prevents creatures other than you from opening it, which reactivates after 1d10 minutes if dispelled.
If you lose attunement to this item all the pages immediately become blank, but if you attune to it again within 2d4-1 days (rolled secretly by the DM), your enscribed spells reappear.
